1.4 Product Overview
An adjustable frequency drive is an electronic motor
controller that converts AC line power input into a variable
AC waveform output. The frequency and voltage of the
output are regulated to control the motor speed or torque.
The adjustable frequency drive can vary the speed of the
motor in response to system feedback, such as position
sensors on a conveyor belt. The adjustable frequency drive
can also regulate the motor by responding to remote
commands from external controllers.
In addition, the adjustable frequency drive 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.

2.2 Pre-Installation Check List
•Before unpacking the adjustable frequency drive,
ensure the packaging is intact. If any damage has
occurred, immediately contact the shipping
company to claim the damage.
•Before unpacking the adjustable frequency drive,
locate it as close as possible to the final instal-
lation site
•Compare the model number on the nameplate to
what was ordered to verify the proper equipment
•Ensure each of the following are rated for the
same voltage:
•Line power
•Adjustable frequency drive
•Motor
•Ensure that adjustable frequency drive output
current rating is equal to or greater than motor
full load current for peak motor performance
•Motor size and adjustable frequency
drive power must match for proper
overload protection
•If adjustable frequency drive rating is
less than motor, full motor output
cannot be achieved
2.3 Mechanical Installation
2.3.1 Cooling
•Top and bottom clearance for air cooling must be
provided. Generally, 9 in [225 mm] is required.
•Improper mounting can result in overheating and
reduced performance.
•Derating for temperatures starting between 113°F
[45°C] and 122°F [50°C] and elevation 3,300 ft
[1,000 m] above sea level must be considered.
See VLT®Design Guide for detailed information.
The high power adjustable frequency drives utilize a
backchannel cooling concept that removes heatsink
cooling air, which carries approximately 90% of the heat
out of the back channel of the adjustable frequency drives.
The backchannel air can be redirected from the panel or
room using one of the kits below.
Duct cooling
A backchannel cooling kit is available to direct the heatsink
cooling air out of the panel when an IP20/chassis
adjustable frequency drives 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.
Cooling out the back (top and bottom covers)
The backchannel cooling air can be ventilated out of the
room so that the heat from the backchannel is not
dissipated into the control room.
A door fan or fans are required on the enclosure to
remove the heat not contained in the backchannel of the
adjustable frequency drives 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 heatsink must be ensured.
The flow rate is shown in Table 2.3.
The fan runs for the following reasons:
•AMA
•DC Hold
•Pre-Mag
•DC Brake
•60% of nominal current is exceeded
•Specific heatsink temperature exceeded (power
size dependent)
•Specific Power Card ambient temperature
exceeded (power size-dependent)
•Specific Control Card ambient temperature
exceeded

For your safety, comply with the following requirements
•Electronic controls equipment is connected to
hazardous AC line voltage. Extreme care should
be taken to protect against electrical hazards
when applying power to the unit.
•Run motor cables from multiple adjustable
frequency drives separately. Induced voltage from
output motor cables run together can charge
equipment capacitors even with the equipment
turned off and locked out.
•Field wiring terminals are not intended to receive
a conductor one size larger.
Overload and Equipment Protection
•An electronically activated function within the
adjustable frequency drive 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
8 Warnings and Alarms for details on the trip
function.
•Because the motor wiring carries high frequency
current, it is important that wiring for line power,
motor power, and control is run separately. Use
metallic conduit or separated shielded wire. See
Figure 2.3. Failure to isolate power, motor, and
control wiring could result in less than optimum
equipment performance.
•All adjustable frequency drives must be provided
with short-circuit and overcurrent protection.
Input fusing is required to provide this
protection, see Figure 2.4. If not factory supplied,
fuses must be provided by the installer as part of
the installation. See maximum fuse ratings in
10.3.1 Protection.

Wire Type and Ratings
•All wiring must comply with local and national
regulations regarding cross-section and ambient
temperature requirements.
•Danfoss recommends that all power connections
be made with a minimum 167°F [75°C] rated
copper wire.
2.4.2 Grounding Requirements
WARNING
GROUNDING HAZARD!
For operator safety, it is important to ground the
adjustable frequency drive properly in accordance with
national and local electrical codes as well as instructions
contained within this document. Do not use conduit
connected to the adjustable frequency drive as a
replacement for proper grounding. Ground currents are
higher than 3.5 mA. Failure to ground the adjustable
frequency drive properly could result in death or serious
injury.
NOTE!
It is the responsibility of the user or certified electrical
installer to ensure correct grounding 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 2.4.2.1 Leakage Current (>3.5 mA)
•A dedicated ground wire is required for input
power, motor power and control wiring
•Use the clamps provided with the equipment for
proper ground connections
•Do not ground one adjustable frequency drive to
another in a “daisy chain” fashion
•Keep the ground wire connections as short as
possible
•Using high-strand wire to reduce electrical noise
is recommended
•Follow the motor manufacturer wiring
requirements
2.4.2.1 Leakage Current (>3.5 mA)
Follow national and local codes regarding protective
grounding of equipment with a leakage current >3.5 mA.
Adjustable frequency drive technology implies high
frequency switching at high power. This will generate a
leakage current in the ground connection. A fault current
in the adjustable frequency drive at the output power
terminals might contain a DC component, which can
charge the filter capacitors and cause a transient ground
current. The ground leakage current depends on various
system configurations including RFI filtering, shielded
motor cables, and adjustable frequency drive power.
EN/IEC61800-5-1 (Power Drive System Product Standard)
requires special care if the leakage current exceeds 3.5 mA.
Grounding must be reinforced in one of the following
ways:
•Ground wire of at least 0.016 in2[10 mm2]
•Two separate ground wires both complying with
the dimensioning rules
See EN 60364-5-54 § 543.7 for further information.
Using RCDs
Where residual current devices (RCDs) – also known as
ground leakage circuit breakers (ELCBs) – are used, comply
with the following: residual current devices (RCDs)
