1. Safety Warnings
1.1. Important Safety Information
Please read the IMPORTANT SAFETY INFORMATION below, and all Warning and Caution information elsewhere.
Danger: Indicates a risk of electric shock, which,
if not avoided, could result in damage to the
equipment and possible injury or death.
This variable speed drive product (E3 drive) is intended for
professional incorporation into complete equipment or systems
as part of a fixed installation. If installed incorrectly it may present
a safety hazard. The E3 drive uses high voltages and currents,
carries a high level of stored electrical energy, and is used to
control mechanical plant that may cause injury. Close attention
is required to system design and electrical installation to avoid
hazards in either normal operation or in the event of equipment
malfunction. Only qualified electricians are allowed to install
and maintain this product.
System design, installation, commissioning and maintenance
must be carried out only by personnel who have the necessary
training and experience. They must carefully read this safety
information and the instructions in this Guide and follow all
information regarding transport, storage, installation and use of
the E3 drive, including the specified environmental limitations.
Do not perform any flash test or voltage withstand test on the E3
drive. Any electrical measurements required should be carried
out with the E3 drive disconnected.
Electric shock hazard! Disconnect and ISOLATE the E3 drive
before attempting any work on it. High voltages are present
at the terminals and within the drive for up to 10 minutes after
disconnection of the electrical supply. Always ensure by using a
suitable multimeter that no voltage is present on any drive power
terminals prior to commencing any work.
Where supply to the drive is through a plug and socket
connector, do not disconnect until 10 minutes have elapsed after
turning off the supply.
Ensure correct earthing connections. The earth cable must
be sufficient to carry the maximum supply fault current which
normally will be limited by the fuses or MCB. Suitably rated
fuses or MCB should be fitted in the mains supply to the drive,
according to any local legislation or codes.
Ensure correct earthing connections and cable selection as per
defined by local legislation or codes. The drive may have a
leakage current of greater than 3.5mA; furthermore the earth
cable must be sufficient to carry the maximum supply fault current
which normally will be limited by the fuses or MCB. Suitably
rated fuses or MCB should be fitted in the mains supply to the
drive, according to any local legislation or codes.
Do not carry out any work on the drive control cables whilst
power is applied to the drive or to the external control circuits.
Danger: Indicates a potentially hazardous situation
other than electrical, which if not avoided, could
result in damage to property.
Within the European Union, all machinery in which this product
is used must comply with Directive 2006/42/EC, Safety of
Machinery. In particular, the machine manufacturer is responsible
for providing a main switch and ensuring the electrical equipment
complies with EN60204-1.
The level of integrity offered by the E3 drive control input
functions – for example stop/start, forward/reverse and
maximum speed is not sufficient for use in safety-critical
applications without independent channels of protection. All
applications where malfunction could cause injury or loss of
life must be subject to a risk assessment and further protection
provided where needed.
The driven motor can start at power up if the enable input signal
is present.
The STOP function does not remove potentially lethal high
voltages. ISOLATE the drive and wait 10 minutes before starting
any work on it. Never carry out any work on the Drive, Motor or
Motor cable whilst the input power is still applied.
The E3 drive can be programmed to operate the driven motor at
speeds above or below the speed achieved when connecting
the motor directly to the mains supply. Obtain confirmation from
the manufacturers of the motor and the driven machine about
suitability for operation over the intended speed range prior to
machine start up.
Do not activate the automatic fault reset function on any systems
whereby this may cause a potentially dangerous situation.
When mounting the drive, ensure that sufficient cooling is provided.
Do not carry out drilling operations with the drive in place, dust
and swarf from drilling may lead to damage.
The entry of conductive or flammable foreign bodies should be
prevented. Flammable material should not be placed close to
the drive
Relative humidity must be less than 95% (non-condensing).
Ensure that the supply voltage, frequency and no. of phases (1
or 3 phase) correspond to the rating of the E3 drive as delivered.
Never connect the mains power supply to the Output terminals
U, V, W.
Do not install any type of automatic switchgear between the
drive and the motor.
Wherever control cabling is close to power cabling, maintain
a minimum separation of 100 mm and arrange crossings
at 90 degrees. Ensure that all terminals are tightened to the
appropriate torque setting.
Do not attempt to carry out any repair of the E3 drive. In the case
of suspected fault or malfunction, contact your local Bardac
Sales Partner for further assistance.

4.3. Protective Earth (PE) Connection
Grounding Guidelines
The ground terminal of each E3 drive should be individually connected DIRECTLY to the site ground bus bar (through the filter if
installed). E3 drive ground connections should not loop from one drive to another, or to, or from any other equipment. Ground loop
impedance must confirm to local industrial safety regulations. To meet UL regulations, UL approved ring crimp terminals should be
used for all ground wiring connections.
The drive Safety Ground must be connected to system ground. Ground impedance must conform to the requirements of national and
local industrial safety regulations and/or electrical codes. The integrity of all ground connections should be checked periodically.
Protective Earth Conductor
The Cross sectional area of the PE Conductor must be at least equal to that of the incoming supply conductor.
Safety Ground
This is the safety ground for the drive that is required by code. One of these points must be connected to adjacent building steel
(girder, joist), a floor ground rod, or bus bar. Grounding points must comply with national and local industrial safety regulations and/
or electrical codes.
Motor Ground
The motor ground must be connected to one of the ground terminals on the drive.
Ground Fault Monitoring
As with all inverters, a leakage current to earth can exist. The E3 drive is designed to produce the minimum possible leakage current
whilst complying with worldwide standards. The level of current is affected by motor cable length and type, the effective switching
frequency, the earth connections used and the type of RFI filter installed. If an ELCB (Earth Leakage Circuit Breaker) is to be used, the
following conditions apply:
 A Type B Device must be used.
 The device must be suitable for protecting equipment with a DC component in the leakage current.
 Individual ELCBs should be used for each E3 drive.
Shield Termination (Cable Screen)
The safety ground terminal provides a grounding point for the motor cable shield. The motor cable shield connected to this terminal
(drive end) should also be connected to the motor frame (motor end). Use a shield terminating or EMI clamp to connect the shield to
the safety ground terminal.
4.4. Incoming Power Connection
4.4.1. Cable Selection
 For 1 phase supply, the mains power cables should be connected to L1/L, L2/N.
 For 3 phase supplies, the mains power cables should be connected to L1, L2, and L3. Phase sequence is not important.
 For compliance with CE EMC requirements, refer to section 4.12. EMC Compliant Installation on page 18.
 A fixed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed between the E3 drive
and the AC Power Source. The disconnecting device must conform to the local safety code / regulations (e.g. within Europe,
EN60204-1, Safety of machinery).
 The cables should be dimensioned according to any local codes or regulations. Maximum dimensions are given in section 10.3.
Rating Tables on page 54.
4.4.2. Fuse / Circuit Breaker Selection
 Suitable fuses to provide wiring protection of the input power cable should be installed in the incoming supply line, according
to the data in section 10.3. Rating Tables on page 54. The fuses must comply with any local codes or regulations in place.
In general, type gG (IEC 60269) or UL type J fuses are suitable; however in some cases type aR fuses may be required. The
operating time of the fuses must be below 0.5 seconds.
 Where allowed by local regulations, suitably dimensioned type B MCB circuit breakers of equivalent rating may be utilised in
place of fuses, providing that the clearing capacity is sufficient for the installation. For UL approved installation, fuses must be used,
refer to section 10.5. Additional Information for UL Compliance on page 55.
 The maximum permissible short circuit current at the E3 drive Power terminals is shown in section 10.2. Input Power Supply
Requirements on page 54.

4.4.3. Optional Input Choke
 Do not use input choke with size 4 models!
 An optional Input Choke is recommended to be installed in the supply line for drives frame size 1, 2 and 3 where any of the
following conditions occur:
o The incoming supply impedance is low or the fault level / short circuit current is high.
o The supply is prone to dips or brown outs.
o An imbalance exists on the supply (3 phase drives).
o The power supply to the drive is via a busbar and brush gear system (typically overhead Cranes).
 In all other installations, an input choke is recommended to ensure protection of the drive against power supply faults. Part numbers
are shown in the table.

4.5. Motor Connection
 The drive inherently produces fast switching of the output voltage (PWM) to the motor compared to the mains supply. For motors
which have been wound for operation with a variable speed drive additional measures are not required; however if the quality of
insulation is unknown the motor manufacturer should be consulted and preventative measures may be required.
 The motor should be connected to the E3 drive U, V, and W terminals using a suitable 3 or 4 core cable. Where a 3 core cable
is utilised, with the shield operating as an earth conductor, the shield must have a cross sectional area at least equal to the phase
conductors when they are made from the same material. Where a 4 core cable is utilised, the earth conductor must be of at least
equal cross sectional area and manufactured from the same material as the phase conductors.
 The motor earth must be connected to one of the E3 drive earth terminals.
 Maximum permitted motor cable length for all models: 100 metres shielded, 150 metres unshielded.
 Where multiple motors are connected to a single drive using parallel cables, an output choke must be installed.
4.6. Motor Terminal Box Connections
Do not install any mechanical or electro-mechanical switching devices between the drive and motor. Where a local isolator is installed
close to the motor, this should be interlocked with the drive control circuit to ensure the drive is disabled when the motor is isolated.
Most general purpose motors are wound for operation on dual voltage supplies. This is indicated on the nameplate of the motor. This
operational voltage is normally selected when installing the motor by selecting either STAR or DELTA connection. STAR always gives
the higher of the two voltage ratings.

4.7. Control Terminal Wiring
 All analog signal cables should be suitably shielded. Twisted pair cables are recommended.
 Power and Control Signal cables should be routed separately where possible, and must not be routed parallel to each other.
 Signal levels of different voltages e.g. 24 Volt DC and 110 Volt AC, should not be routed in the same cable.
 Maximum control terminal tightening torque is 0.5Nm.
 Control Cable entry conductor size: 0.05 – 2.5mm2/ 30 – 12 AWG.
