·Keep the drive away from explosive gas.
·Only qualified personnel shall wire the drive.
·Note that the control terminal of EV1000 drive is of ELV (Extra
Low Voltage) circuit, therefore, do not connect the control terminal
with other devices directly. For example, before connecting the
RS485 terminal with the PC’s RS232 terminal, an adapter with
isolating protections must be connected in between;
·Never wire the drive unless the input AC supply is totally
disconnected; otherwise, there is danger of electric shock. During
power-on, do not touch the cables, control terminals, radiator and
the pore plate on the housing of the drive.
·The drive must be properly earthed to reduce electrical accident.
·Install the cover before switching on the drive, to reduce the
danger of electric shock and explosion.
·
For drives that have been stored for longer than 2 years, increase
its input voltage gradually before supplying full rated input voltage
to it in order to avoid electric shock and explosion.
·Perform the maintenance job after confirming that the charging
LED is off or the DC Bus voltage is below 36V.
·Only trained professionals can change the components, it is
prohibited to leave wires or metal parts inside the drive to avoid
the risk of fire.
·Parameter settings of the control board that has been changed
must be revised, otherwise accidents may occur.
·The bare portions of the power cables must be bound with
insulation tapes.
·When using optional parts, it is recommended to use those
provided by Emerson Network Power, to secure safety.
Attention
!
·Don’t carry the drive by its cover. Its cover cannot sustain the

1.3 Notes For Using The Drive
Pay attention to the following issues when using EV1000
Series drive:
1.3.1 About Motor And Load
Compared to working at mains frequency, there will be some
increase in temperature, noise and vibration in the motor.
The EV1000 Series are voltage source inverters. Its output
voltage is in PWM wave. Being non-sinusoidal, there will be
some harmonics.
Low Speed Rotation with Constant Torque
When a standard motor is driven at low speed for a long time,
there will be insufficient cooling for a self-ventilated motor.
Overheating can result in insulation damaged. Special
variable frequency motor is recommended for constant
torque operation at low speed.
Motor’s over-temperature protecting threshold
The drive can protect the motor from over-temperature. If the
power rating of the drive is greater than the motor, be sure to
adjust the protection parameters to ensure the motor is
properly protected.
Operate above 50Hz
When running the motor above 50Hz, there will be increase
in vibration and noise. The rate at which the torque is
available from the motor is inversely proportionally to its
increase in running speed. Ensure that the motor can still
provide sufficient torque to the load.
Lubrication of mechanical devices
Over time, the lubricants in mechanical devices, such as
gear box, geared motor, etc. when running at low speed, will
deteriorate. Frequent maintenance is recommended.
Regenerative Energy
When lifting load, regenerative energy is produced, the drive
will trip on overvoltage when it cannot absorb the
regenerative energy of the load. Therefore, a proper braking
unit is required.

Chapter 1 Safety Information 3
EV1000 Series General Purpose Variable Speed Drive User Manual
Mechanical resonance point of load
The drive system may encounter mechanical resonance with
the load when operating within certain band of output
frequency. Skip frequencies have to be set to avoid it.
Frequent start and stop
The drive should be started and stopped via its control
terminals. It is prohibited to start and stop the drive directly
through contactors at the input side, which may damage the
drive.
Insulation of Motors
Before using the drive, the insulation of the motors must be
checked, especially, if it is used for the first time or if it has
been stored for a long time. This is to reduce the risk of the
drive from being damaged by the poor insulation of the
motor winding. Wiring diagram is shown in Figure 1-1.
Please use 500V insulation tester to measure the insulation
resistance. It should not be less than 5MΩ.
1.3.2 About Variable Speed Drive
Varistors for Surge Protection or Capacitors Used to Improve
the Power Factor
Don't connect any varistor or capacitor to the output
terminals of the drive, because the drive's output voltage
waveform is pulse wave. Tripping or damage to components
may occur as shown in Figure1-1.

U
V
W
EV1000
Drive
Figure 1-1 Capacitors at output are prohibited
Circuit breakers connected to the output of the drive
If circuit breaker or contactor needs to be connected
between the drive and the motor, be sure to operate these
circuit breakers or contactor when the drive has no output to
avoid damaging of the drive.
Using host communication function
When the parameters are modified frequently through host
communication function, improper command will result in
erasable memory damaged. If no need to save upon
power-off, please do not use 0x41 command. Please refer to
Appendix 2.
Using outside rated voltage
The drive is not suitable to be used out of the specified range
of operation voltage. If needed, please use suitable voltage
regulation device.
Protection against lightning strike
There are transient surge suppressors inside the drive that
protect it against lighting strike.
Derating due to Altitude
Derating must be considered when the drive is installed at
high altitude, greater than 1000m. This is because the
cooling effect of the drive is less effective in the thin air.
Figure1-2 that shows the relationship between the altitude
and rated current of the drive.

1.4 Disposing Unwanted Drive
When disposing the drive, pay attention to the following
factors:
The capacitors may explode when they are burnt.
Poisonous gas may be generated when the plastic parts like
front covers are burnt.
Disposing method: Please dispose the drive as industrial
waste.

3.1.1 EMC Compliance Installation
In a traction system composed of the drive and a motor, if
the drive, controllers and transducer are installed in one
cabinet, the disturbance they generate should be depressed
at the connection points, therefore, a noise filter and inrush
reactor should be installed in the cabinet, so that EMC
requirement is met inside it.
The drive is usually installed in a metal cabinet. The
instruments outside the metal cabinet is shielded and may
be disturbed lightly. The cables are the main EMI source, if
you connect the cables according to the manual, the EMI
can be suppressed effectively.
In system design phase, to reduce EMI, insulating the noise
source and using noise snubber are best choice. But the
cost is considerable. If there are a few sensitive devices on
site, just install power line filter beside them is enough. Note
that the drive and contactor are noise source, and the
automatic devices, encoder and transducer are sensible to
them.
Divide the system into several EMC areas, refer to Figure
3-4.
Note
1. After installing EMI filter and AC reactor, the drive can satisfy IEC 61800-3 standard.
2. The input/output EMI filter should be installed close to the drive as possible.
3. Refer toAppendix 3 for the specifications of optional parts.

3.1.2 Noise Suppression
The noise generated by the drive may disturb the equipment nearby. The degree of disturbance is dependent on the drive
system, immunity of the equipment, wire connections, installation clearance and earthing methods.
Table 3-1 Method of Noise Suppression
Noise emission paths Actions to reduce the noise
If the external equipment shares the same AC
supply with the drive, the drive’s noise may be
transmitted along its input power supply
cables, which may cause nuisance tripping to
other external equipment.
Install noise filter at the input side of the drive, and use an isolation transformer or line filter
to prevent the noise from disturbing the external equipment.
If the signal cables of measuring meters,
radio equipment and sensors are installed in
a cabinet together with the drive, these
equipment cables will be easily disturbed.
1) The equipment and the signal cables should be as far away as possible from the drive.
The signal cables should be shielded and the shielding layer should be grounded. The
signal cables should be placed inside a metal tube and should be located as far away as
possible from the input/output cables of the drive. If the signal cables must cross over the
power cables, they should be placed at right angle to one another.
2) Install radio noise filter and linear noise filter (ferrite common-mode choke) at the input
and output sides of the drive to suppress the emission noise of power lines.
3) Motor cables should be placed in a tube thicker than 2mm or buried in a cement
conduit. Power cables should be placed inside a metal tube and be grounded by shielding
layer (Motor cable should be a 4-core cable, where one core should be connected to the
PE of the drive and another should be connected to the motor’s enclosure) .
If the signal cables are routed in parallel with
the power cables or bundle these cables
together, the induced electro-magnetic noise
and induced ESD noise may disturb the
signal cables.
Avoide this kind of routing. Other equipment sensibleto EMI should also be located as far
away as possible from the drive. The signal cables should be placed inside a metal tube
and should be placed as far away as possible from the input/output cables of the drive.
The signal cables and power cables should be shielded cables. EMC interference will be
further reduced if they could be placed inside metal tubes. The clearance between the
metal tubes should be at least 20cm.

3.1.3 Using Surge Suppressor
The devices such as relay, contactor and electro-magnetic
braking kit, which may generate great noises, should be
installed with surge suppressors even if installed outside of
the drive cabinet.

3.1.4 Leakage Current
Leakage current may flow through the drive’s input and
output capacitors and the motor’s capacitor. The leakage
current value is dependent on the distributed capacitance
and carrier wave frequency. The leakage current includes
ground leakage current and the leakage current between
lines.
Ground leakage current
The ground leakage current not only flows into the drive
system, but also into other equipment via earthing cables. It
may cause leakage current circuit breaker and relays to be
falsely activated. The higher the drive’s carrier wave
frequency, the higher the leakage current, and also, the
longer the motor cable, the greater is the leakage current.
Suppressing methods:
Reduce the carrier wave frequency, but the motor noise may
be higher.
Motor cables should be as short as possible;
The drive and other equipment should use leakage current
circuit breaker designed for protecting the product against
high-order harmonics/surge leakage current.
Leakage current between lines
The line leakage current flowing outside through the
distributed capacitors of the drive may false trigger the
thermal relay, especially for the drive of which power rating is
less than 7.5kW. When the cable is longer than 50m, the
ratio of leakage current to motor rated current may increase
to a level that can cause the external thermal relay to trigger
unexpectedly.
Suppression methods:
Reduce the carrier wave frequency, but the motor audible
noise is higher.
Install reactor at the output side of the drive.
In order to protect the motor reliably, it is recommended to
use a temperature sensor to detect the motor’s temperature,
and use the drive’s over-load protection device (electronic
thermal relay) instead of an external thermal relay.
3.1.5 Applications Of Power Filter
Power source filter should be used in the equipment that
may generate strong EMI or the equipment that is sensitive
to EMI. The power source filter should be a low pass filter
through which only 50Hz current can flow and high
frequency current is rejected.
The power line filter ensures the equipment can satisfy the
conducting emission and conducting sensitivity in EMC
standard. It can also suppress the radiated emission of the
equipment.
It can prevent the EMI generated by the equipment from
entering power cable, and also prevent the EMI generated
by power cable from entering equipment.
Common mistakes in using power line filter
1. Too long power cable
The filter inside the cabinet should be located near to the
input power source. The length of the power cables should
be as short as possible.
2. The input and output cables of the AC supply filter are too
close
The distance between input and output cables of the filter
should be as far apart as possible, otherwise the high
frequency noise may be coupled between the cables and
bypass the filter. Thus, the filtering effect becomes
ineffective.
3. Bad earthing of filter
The filter’s enclosure must be connected properly to the
metal casing of the drive. In order to be earthed well, a
special earthing terminal on the filter’s enclosure should be
used. If you use one cable to connect the filter to the case,
the earthing is useless due to high frequency interference.
When the frequency is high, so too is the impedance of
cable, hence there is little bypass effect.
The filter should be mounted in the enclosure of equipment.
Ensure to clear away the insulation paint between the filter
case and the enclosure for good earth contact.
3.1.6 AC Line Reactor Applications
Input AC Line Reactor
A line reactor should be used if the distortion of power
network is severe or the input current harmonic level is high
even after a DC reactor has been connected to the drive. It
can also be used to improve the AC input power factor of the
drive.
Output AC Line Reactor
When the cables from the drive to motor are longer than
80m, multi-strand cables and an AC line reactor should be

12 Chapter 3 Installation and Wiring
EV1000 Series General Purpose Variable Speed Drive User Manual
used to suppress the high frequency harmonics. Thus, the
motor insulation is protected. At the same time, leakage
current and unexpected trigger are reduced.
3.2 Wiring
Danger
!
·Wiring can only be done after the Variable Speed Drive’s AC
power is disconnected, all the LEDs on the operation panel are off
and after waiting for at least 5 minutes. Then, you can remove the
panel.
·Wiring job can only be done after confirming the Charge
indicator inside the drive has extinguished and the voltage
between main circuit power terminals + and - is below DC36V.
·Wire connections can only be done by trained and authorized
personnel.
·Check the wiring carefully before connecting emergency
stopping or safety circuits.
·For the sake of safety, the drive and motor must be earthed
because there is leakage current inside the drive.
·
Check the Variable Speed Drive’s voltage level before supplying
power to it, otherwise human injuring or equipment damage may
happen.
Attention
!
·Check whether the Variable Speed Drive’s rated input voltage is
in compliant with the AC supply voltage before using.
·Dielectric strength test of the drive has been done in factory and
the user needs not do it again.
·Refer to chapter 2 on how to connect braking resistor or braking
kit.
·It is prohibited to connect the AC supply cables to the drive’s
terminals U, V and W.
·Grounding cables should be copper cables with cross-sectional
area bigger than 3.5mm2, and the grounding resistance should be
less than 10Ω.
·The drive should be connected to the AC supply via a circuit
breaker or fuse to provide input over-current protection and also for
maintenance purpose.
·The control circuits are isolated from the power circuits in the
drive by basic insulation (single insulation) only. If the control
cables are to connect to external control circuit exposing to human
contact, an extra insulating layer, rated for use at the AC supply
voltage of the load, must be applied.
·If the control circuits are to connect to other circuits classified as
Safety Extra Low Voltage (SELV) , e.g. connecting the RS485 port
of the drive to a personal computer through an adapter, an
additional isolating barrier must be included in order to maintain
the SELV classification.
Attention
!
·The control terminals of the drive is of ELV (Extra Low Voltage)
circuit. Do not touch them once energized;
·If the external device has touchable terminals of SELV (Safety
Extra Low Voltage) circuit. Remember to connect isolating
protections in between. Otherwise, the SELV circuit will be
degraded to ELV circuit;
·When connecting the drive with PC, do choose RS485/232
adapters with isolating protections that measure up to safety
requirements.
3.2.1 Overview
You should finish the power circuit and control circuit wiring.
First, remove the screws on the keypad, open the front door

1. When using analog input, you should install capacitor-filter or
common-mode inductor between VCI and GND, or between CCI

2. Analog I/O signals are sensible to interference, ensure to use
shielded cable and ground it properly. The cable length should be
as short as possible.
3) Serial Communication Port Connection
The drive can be connected to the host with RS485 port
directly.
Figure 3-12 shows the connection of the drive with the host
with RS232 port.
Figure 3-13 shows the connection of the drive to PROFIBUS
system via TDS-PA01 PROFIBUS adapter.
Using above wiring method, you can build a “single-master
single slave” system or a “single-master multi-slaves”
system. The drives in the network can be monitored, and be
controlled remotely and automatically in real time by using a
PC or PLC controller. Thus more complicated operation
control can be realized.

Precautions for communication port connection:
zThe PE terminal of each drive should be earthed at a
nearby grounding point;
zThe GND terminal of each drive should be connected
together;
zRS485 communication uses shielded cables, which is
earthed at one side. The earth wire of the shielded cable
is connected to RS485 communication module (PE) .
If the above standard wiring methods cannot meet the
requirements, you can take the actions below:
zUse isolated RS485 communication module;
zIf the noise is transmitted through the GND line to the
drive or other devices, which results in malfunction of
them, you may disconnect the GND lines.
4) Multi-function Input Terminal and FWD, REV Wiring
The multi-function input terminals use full-bridge rectifying
circuit, as the below figure shows. PLC is the common
terminal for X1~X5, FWD and REV. The PLC terminal can
sink or source current. Wire connections X1~X5, FWD and
REV is flexible and the typical wiring is shown below:
①Connection method 1
It is default to use the drive’s internal power source 24V, i.e.
PLC connected with P24.
If you want to use external power supply, make sure to
remove the wire between PLC and P24.

Note
1. Don’t short terminals P24 and COM, otherwise the control
board may be damaged.
2. Use multi-core shielded cable or multi-strand cable (above
1mm) to connect the control terminals.
3. When using a shielded cable, the shielded layer’s end that is
nearer to the drive should be connected to PE.
4. The control cables should be as far away (at least 20cm) as
possible from the main circuits and high voltage cables (including
power supply cables, motor cables, relay cables and cables of
contactor) . The cables should be vertical to each other to reduce
the disturbance to minimum.
3.2.4 Onsite Wiring Requirements
To avoid mutual EMI disturbance, the control cables, power
cable and motor cable should be installed as apart as
