Frequency converters contain DC-link capacitors that can
remain charged even when the frequency converter is not
powered. To avoid electrical hazards, disconnect AC mains,
any permanent magnet type motors, and any remote DC-
link power supplies, including battery backups, UPS and
DC-link connections to other frequency converters. Wait for
the capacitors to fully discharge before performing any
service or repair work. The amount of wait time is listed in
the Discharge Time table. Failure to wait the specified time
after power has been removed before doing service or
repair could result in death or serious injury.
WARNING
DISCHARGE TIME!

1.4 Product Overview
A frequency converter is an electronic motor controller
that converts AC mains input into a variable AC waveform
output. The frequency and voltage of the output are
regulated to control the motor speed or torque. The
frequency converter can vary the speed of the motor in
response to system feedback, such as changing
temperature or pressure for controlling fan, compressor, or
pump motors. The frequency converter can also regulate
the motor by responding to remote commands from
external controllers.
In addition, the frequency converter monitors the system
and motor status, issues warnings or alarms for fault
conditions, starts and stops the motor, optimizes energy
efficiency, and offers many more control, monitoring, and
efficiency functions. Operation and monitoring functions
are available as status indications to an outside control
system or serial communication network.

2 Installation
2.1 Installation Site Check List
•
The frequency converter relies on the ambient air
for cooling. Observe the limitations on ambient
air temperature for optimal operation
•
Ensure that the installation location has sufficient
support strength to mount the frequency
converter
•
Keep the manual, drawings, and diagrams
accessible for detailed installation and operation
instructions. It is important that the manual is
available for equipment operators.
•
Locate equipment as near to the motor as
possible. Keep motor cables as short as possible.
Check the motor characteristics for actual
tolerances. Do not exceed
•
300 m (1000 ft) for unshielded motor
leads
•
150 m (500 ft) for shielded cable.
•
Ensure that the ingress protection rating of the
frequency converter is suitable for the installation
environment. IP55 (NEMA 12) or IP66 (NEMA 4)
enclosures may be necessary.
CAUTION
Ingress protection
IP54, IP55 and IP66 ratings can only be guaranteed if the
unit is properly closed.
•
Ensure that all cable glands and unused holes for
glands are properly sealed.
•
Ensure that the unit cover is properly closed
CAUTION
Device damage through contamination
Do not leave the frequency converter uncovered.
2.2 Frequency Converter and Motor Pre-
installation Check List
•
Compare the model number of unit on the
nameplate to what was ordered to verify the
proper equipment
•
Ensure each of the following are rated for same
voltage:
Mains (power)
Frequency converter
Motor
•
Ensure that the frequency converter output
current rating is equal to or greater than motor
full load current for peak motor performance
Motor size and frequency converter
power must match for proper overload
protection
If frequency converter rating is less than
motor, full motor output cannot be
achieved
2.3 Mechanical Installation
2.3.1 Cooling
•
To provide cooling airflow, mount the unit to a
solid flat surface or to the optional back plate
(see 2.3.4 Mounting)
•
Top and bottom clearance for air cooling must be
provided. Generally, 100-225 mm (4-10 in) is
required. See Illustration 2.1 for clearance
requirements
•
Improper mounting can result in over heating
and reduced performance
•
Derating for temperatures starting between 40 °C
(104 °F) and 50 °C (122 °F) and elevation 1000 m
(3300 ft) above sea level must be considered.

2.3.2 Cooling and Airflow (125 HP and above)
Cooling
Cooling can be obtained in different ways, by using the cooling ducts in the bottom and the top of the unit, by taking air
in and out the back of the unit or by combining the cooling possibilities.
Duct cooling
A back-channel cooling kit is available to direct the heatsink cooling air out of the panel when an IP20/chassis frequency
converters is installed in a Rittal enclosure. Use of this kit reduces the heat in the panel and smaller door fans can be
specified on the enclosure.
Back cooling
The back channel cooling air can be ventilated out of the room so that the heat from the back channel is not dissipated
into the control room. A door fan(s) is required on the enclosure to remove the heat not contained in the backchannel of
the frequency converters and any additional losses generated by other components inside the enclosure. The total required
air flow must be calculated so that the appropriate fans can be selected.
Airflow
The necessary airflow over the heat sink must be secured. The flow rate is in Table 2.2.

CAUTION
WIRING ISOLATION!
Run input power, motor wiring and control wiring in three
separate metallic conduits or use separated shielded cable
for high frequency noise isolation. Failure to isolate power,
motor and control wiring could result in less than
optimum frequency converter and associated equipment
performance.
For your safety, comply with the following requirements.
•
Electronic controls equipment is connected to
hazardous mains voltage. Extreme care should be
taken to protect against electrical hazards when
applying power to the unit.
•
Run motor cables from multiple frequency
converters separately. Induced voltage from
output motor cables run together can charge
equipment capacitors even with the equipment
turned off and locked out.
Overload and Equipment Protection
•
An electronically activated function within the
frequency converter provides overload protection
for the motor. The overload calculates the level of
increase to activate timing for the trip (controller
output stop) function. The higher the current
draw, the quicker the trip response. The overload
provides Class 20 motor protection. See
10 Warnings and Alarms for details on the trip
function.
•
Because the motor wiring carries high frequency
current, it is important that wiring for mains,
motor power, and control are run separately. Use
metallic conduit or separated shielded wire.
Failure to isolate power, motor, and control
wiring could result in less than optimum
equipment performance.
•
All frequency converters must be provided with
short-circuit and over-current protection. Input
fusing is required to provide this protection, see
Illustration 2.6. See maximum fuse ratings in
13.3 Fuse Specifications.

2.5.2 Earth (Grounding) Requirements
WARNING
GROUNDING HAZARD!
For operator safety, it is important to ground the
frequency converter properly in accordance with national
and local electrical codes as well as instructions contained
within this document. Ground currents are higher than 3.5
mA. Failure to ground the frequency converter properly
could result in death or serious injury.
NOTE
It is the responsibility of the user or certified electrical
installer to ensure correct grounding (earthing) of the
equipment in accordance with national and local electrical
codes and standards.
•
Follow all local and national electrical codes to
ground electrical equipment properly
•
Proper protective grounding for equipment with
ground currents higher than 3.5 mA must be
established, see 2.5.2.1 Leakage Current (>3.5 mA)
•
A dedicated ground wire is required for input
power, motor power and control wiring
