Protect Against
Accidental
Contact

AC motor controls and servo drives contain dangerous voltages which
can cause death or serious injury. During operation they can have live
"energized" un-insulated parts, moving parts, as well as hot surfaces.
Care should be taken to ensure correct and safe operation in order to
minimize risk to personnel and equipment.
All work involving this product, installation, start up as well as mainte-
nance may only be performed by qualied electrical technical person-
nel. According to this manual "qualied" means: those who are able to
recognize and acknowledge the possible dangerous conditions based
on their training and experience and those who are familiar with the
relevant standards and installation codes as well as the eld of power
transmission.
AC motor controls and servo drives must be protected against physical
damage during transport, installation, and use. Components or covers
must not be bent or deformed as this may decrease insulation distanc-
es inside the unit resulting in an unsafe condition. On receipt of the unit
visual damage should be reported immediately to the supplier. DO NOT
ATTEMPT TO POWER UP A UNIT WITH VISIBLE PHYSICAL DAMAGE.
This unit contains electrostatically sensitive components which can be
destroyed by in correct handling. For that reason, disassembly of the
unit or contact with the components should be avoided.
Before any installation and connection work can be done, the supply
voltage must be turned off and locked out. After turning off the supply
voltage, dangerous voltages may still be present within the unit as the
bus capacitors discharge. Therefore it is necessary to wait 5 minutes
before working on the unit after turning off the supply voltage.
The low voltage control terminal strip and communication ports are se-
curely isolated in accordance with EN50178. When connecting to other
systems, it is necessary to verify the insulation ratings of these sys-
tems in order to ensure the EN requirements are still met. When con-
necting the unit to a grounded delta power system, the control circuit
can no longer be classied as a "securely isolated circuit".
Before putting the motor control into operation be sure the connection
terminals are tight and all covers removed for installation have been
replaced.
The AC motor control or servo system can be adjusted to self initiate an
automatic restart in the event of a fault or error condition. The design
of the system must take this into account, such that personnel are safe
guarded against potentially dangerous circumstances.
Software functions in the AC motor control or servo system can be
used to control or regulate external systems. However, in the event of
failure of the motor control or servo system there is no guarantee these
software function(s) will continue to provide the desired level of con-
trol. As a result, when operator or machine safety is at stake, external
elements must be used to supplement or override the software function
within the AC motor control or servo system.

1.4 Mounting instructions
1.4.1 Classication
The elevator drive is classied as an "Open Type" inverter with an IP20
rating and is intended for "use in a pollution degree 2 environment."
The unit must be mounted inside of a control cabinet offering proper
environmental protection.
1.4.2 Physical Mounting
Install the inverter in a stationary location offering a rm mounting point
with low vibration.
Installation of the inverter on a moving system may require special
earth ground connections to the inverter.
For best high frequency grounding, install the inverter on a bare metal
sub-panel, i.e. zinc plated steel or galvanized steel.
Take into consideration the minimum clearance distances when
positioning the inverter (see drawing below). The F5 series inverters
are designed for vertical installation and can be aligned next to each
other. Maintain a distance of at least 2 inches in front of the unit. Make
sure cooling is sufficient.

1.4.3 Harsh Environments
For extended life, prevent dust from getting into the inverter.
When installing the unit inside a sealed enclosure, make sure the
enclosure is sized correctly for proper heat dissipation or that a cooling
system has been installed in the panel.
Protect the inverter against conductive and corrosive gases and
liquids. Water or mist should not be allowed into the inverter.
The F5 elevator drive inverter must be installed in an explosion-proof
enclosure when operating in an explosion-proof environment.

1.5.1 Safety First
CAUTION - RISK OF ELECTRIC SHOCK! Always disconnect supply volt-
age before servicing the F5 Elevator Drive.
After disconnecting the supply voltage, always wait 5 minutes before at-
tempting to change the wiring. The internal DC BUS capacitors must dis-
charge.
1.5.2 Voltage Supply
Pay attention to the supply voltage and be sure the supply voltage matches
that of the inverter. A 230V unit can be supplied with voltage in the range
180 to 260VAC +/-0%, for a 460V unit the range is 305 to 500VAC +/- 0%,
48Hz to 62 Hz.
All 240V models are suitable for use on a circuit capable of delivering not
more than ___ kA rms symmetrical amperes, 240 volts maximum when
protected by class ___ fuses rated ___ Amperes as specied in table 1.5.4.1
or when protected by a circuit breaker having an interrupt rating not less than
___ kA rms symmetrical amperes, 240V maximum, rated ___ amperes as
specied in table 1.5.4.1.
All 480V models are suitable for use on a circuit capable of delivering not
more than ___ kA rms symmetrical amperes, 480 volts maximum when
protected by class ___ fuses rated ___ Amperes as specied in table 1.5.4.2
or when protected by a circuit breaker having an interrupt rating not less than
___ kA rms symmetrical amperes, 480V maximum, rated ___ amperes as
specied in table 1.5.4.2.
1.4.4 Ambient Conditions
Maximum Surrounding Air Temperature 45°C! The operating temperature
range of the unit is -10°C to + 45°C (14°F to +113°F). Operation outside of
this temperature range can lead to shut down of the inverter.
The unit can be stored (power off) in the temperature range -25°C to 70°C
(-13°F to +158°F).
The power rating of the inverter must be derated for operation above 3,300
ft (1000 m). Reduce the rated power 1% for each additional 330 ft (100 m).
The maximum elevation for operation is 6,560 ft (2000 m).
The relative humidity shall be limited to 95% without condensation.
1.5 Electrical connections


General

14
General
Connection of the F5 series inverters to voltage systems congured as a
corner grounded delta, center tap grounded delta, open delta, or ungrounded
delta, may defeat the internal noise suppression of the inverter. Increased high
frequency disturbance in the controller and on the line may be experienced.
A balanced, neutral grounded wye connection is always recommended. The
three phase voltage imbalance must be less than 2% phase to phase. Greater
imbalance can lead to damage of the inverter's power circuit.
1.5.3 Disconnect switch
A disconnect switch or contactor should be provided as a means of turning off the
supply voltage when the unit is not in use or when it must be serviced.
Repetitive cycling on and off of the input supply voltage more than once every
two minutes can lead to damage of the inverter.
1.5.4 Fusing
Integral solid state short circuit protection does not provide branch circuit
protection. Branch circuit protection must be provided in accordance with the
Manufacturer Instructions, National Electrical Code (NFPA70 or CSA22.1) and
any additional local codes.
Branch circuit protection for the F5 must be provided using the fuses as listed in
the tables 1.5.4.1 and 1.5.4.2 below. Fast acting class J fuses are recommended.
As an example, use BUSSMANN type JKS. For installations supplied by an
isolation transformer and that have harmonic lters installed, a high speed
class J fuse must be used (only Ferraz type HSJ is approved).
The minimum voltage rating for protection devices used with 230V inverters shall
be 250VAC. The minimum voltage rating for protection devices used with 460V
inverters shall be 600VAC.

Fuses shall not be installed between the drive and the motor.
In PM motor applications where the drive input current can be lower than the
output current, it is allowed to use a protection device with a lower current rating
thus being able to optimize line side wiring and ancillary components.
If the controller / elevator drive is supplied through an individual isolation
transformer, the maximum fuse amp rating shall not be greater than 125% of the
secondary current rating of the transformer per NFPA70 and CSA 22.1. This
value may be signicantly lower than the values in the preceding tables.
1.5.5 Line Chokes
A line choke with minimum 3% impedance is required for all 230 V inverters 50hp
(size 20) and greater. A line choke with minimum 3% impedance is required for
all 480V inverters 100hp (size 23) and greater.

General
Installation of a line choke is recommended and can be used prevent nuisance
errors and protection caused by voltage spikes. Additionally, the use of a line
choke will double the operational lifetime of the DC bus capacitors in the unit.
1.5.6 Motor Thermal Protection
The F5 series inverters are UL approved as a solid state motor overload
protection device. It is necessary to adjust the current trip level in parameter LF.9
or LF.12. The function assumes the use of a non-ventilated motor. The function
meets the requirements set forth in VDE 0660 Part 104, UL508C section 42,
NFPA 70 Article 430 part C. See the description for parameter LF.9 for the trip
characteristics.
A motor winding sensor can also be used for additional safety and the highest
level of protection. Either a normally closed contact (rating: 15V / 6mA) or a
PTC (positive temperature coefficient) resistor can be connected to the T1, T2
terminals on the inverter. The thermal device should be connected as indicated
in Section 2.5.
1.5.7 Motor Cable Length
In some conventional installations and many MRL applications, the motor can
be a considerable distance (greater then 40 feet) from the elevator drive. Under
these circumstances the long cable length can cause high voltage peaks or high
dv/dt (rate of voltage rise) on the motor windings. Depending on the design of
the motor, these can lead to damage of the motor winding. Therefore, in these
installations use of a special dv/dt lter is highly recommended.
The standard approved solution is a special output choke. The choke is designed
to be used with a maximum of 16kHz switching frequency and low inductance so
it does not drastically inuence the motor's equivalent circuit model.
There are three sizes available for motors rated up to 100A. The part numbers
and current ratings are listed below.
Part Number Rated Current
15Z1F04-1005 22A
17Z1F04-1005 42A
21Z1F04-1005 100A
The use of a conventional line or motor choke on the output of the drive is not
recommend since the inductance value is high enough that it would distort the
values in the motor model and result in poor control of the motor.

1.5.8 High Voltage Connections
Always note inverter voltage, select appropriate over current protection devices,
select disconnect device, and select proper wire size before beginning the wiring
process. Wire the drive according to NFPA 70 Class 1 requirements.
The correct wire gauge for each size inverter can be selected from the charts
under Section 2.1-2.2 . The wire gauge is based on the maximum fuse rating for
the inverter. The terminal tightening torque can be found for each unit in the same
charts.
Always use UL listed and CSA approved wire. Use 60/75°C copper conductors
only for equipment rated 100 Amperes or less and use 75°C Copper Conductors
only for equipment rated grater than 100 Amperes! Use minimum 300V rated wire
with 230V systems and minimum 600V rated wire with 480V systems.
To prevent coupling high frequency noise, the following wires must be spatially
separated from each other a minimum distance of 8 inches (20 cm) when they
are laid parallel to each other :
- AC supply power and motor lines not connected to inverters
- motor lines connected to inverters
- control and data lines ( low-voltage level < 48 V )
When using EMI lters, use only the wire provided with the lter to connect the
lter to the inverter. Do not add additional wire between the lter and the inverter
as this will have a negative effect on the operation of the lter.
1.5.9 Ground Connections
When working with high frequencies ( > 1kHz ) and power semiconductors it is
recommended to make all ground connections with large exposed metal surfaces
in order to minimize the ground resistance.
The metal sub-plate the inverter is mounted on is regarded as the central ground
point for the machine or the equipment. For best results use an unpainted,
galvanized or plated sub-panel.
An additional high frequency ground wire should be connected between the
inverter and the sub-panel. Use a stranded wire equal in size to the main line
conductor or a thick ground strap. This is in addition to the ground wire required
by NFPA 70, UL 508, CSA 22.1
All ground connections should be kept as short as possible and as close as
possible to the ground system, sub-panels.
If other components in the system exhibit problems due to high frequency
disturbances, connect an additional high frequency ground wire between them
and the sub-panel.
The EMI lter should be mounted to the drive or as close as possible to the
inverter and on the same sub-panel as the inverter. Good metallic surface contact
to the sub-panel is required to provide adequate high frequency grounding of the
lter.

2. Technical Data
1.5.10 High Frequency Shielding
Use of shielded cable is recommended when high frequency emissions or easily
disturbed signals are present. Examples are as follows:
- motor wires: connect shield to ground at both the drive and motor, NOTE
the shield should never be used as the protective ground conductor required
by NFPA70 or CSA22.1. Always use a separate conductor for this.
- digital control wires: connect shield to ground at both ends.
- analog control wires: connect shield to ground only at the inverter.
The connection of meshed shields to the ground connection should not be
done through a single strand or drain wire of the shield, but with metallic clamps
to provide 360° contact around the surface of the shield to the ground point.
Connection with a single wire from the braided shield reduces the effectiveness of
the shield 70%. Metal conduit clamps work well for this. Be sure the t is tight.
Ridged metal conduit can be used as the shield of the motor wires. Always
observe the following points :
- remove all paint from the control cabinet and motor housing where the
conduit is fastened
- securely fasten all conduit ttings
- run only the motor wires through the conduit, all other wires, high voltage AC
and low voltage signal, should be pulled through a separate conduit.
- connect the control panel to the Sub-panel with a heavy ground strap.
If EMI lters are used, they should be mounted to the inverter or as close as
possible to the inverter and on the same sub-panel as the inverter. Good metallic
surface contact to the sub-panel is required to provide adequate high frequency
grounding of the lter. Always use the shielding plate provided with the lter when
connecting the lter to the inverter.
Shielding of control wires:
If digital signal wires are terminated on a terminal block in the control panel,
the shields should be rmly connected to the sub-panel on both sides of the
terminal block.
The shields of digital signal wires originating outside the control cabinet which
are not terminated on a terminal block, must be connected to the sub-panel at
the point where the cable enters the control panel and at the inverter.
If the shield is terminated to the sub-panel within 8 inches (20cm) of the
inverter, then the shield no longer needs to be connected to the inverter.
When using un-shielded signal wires, they should always be installed as a
twisted pair (signal and common).
Low voltage signal wires should cross high voltage wires at right angles.

1.5.11 Storage of the Unit
The DC bus of the KEB F5 Combivert is equipped with electrolytic capacitors.
If the electrolytic capacitors are stored de-energized, the oxide lm working as
dielectric uid reacts with the acidic electrolyte and destroys itself slowly. This
affects the dielectric strength and capacity of the unit. If the capacitors start
running with rated voltage again, the oxide lm tries to build up quickly. This
causes heat and gas and leads to the destruction of the capacitors.
In order to avoid failures, the KEB F5 Combivert must be started up according to
the following specication based on duration of storage period (powered off):
Storage Period < 1 Year
*Start up normally, without any additional precautions
Storage Period 1...2 Years
*Power on frequency inverter for one hour without modulation
Storage Period 2...3 Years
*Remove all cables from power circuit, including braking resistor and GTR7 connections
*Open control release
*Connect variable voltage supply to inverter input
*Increase voltage slowly to indicated input level and remain at for the specied time.
Voltage Class Input Voltage Minimum Time
230V 0...160V 15 min
160...220V 15 min
220...260V 1 h
480V 0...280V 15 min
280...400V 15 min
400...500V 1 h
Storage Period > 3 Years
*Input voltages same as above, however double the amount of time for each additional year.
Eventually consider changing capacitors.
