2 Installation
2.1 Safety Information
NOTICE
QUALIFIED PERSONNEL
Only qualified, Danfoss authorized personnel are allowed to install the parts described in these installation instructions.
Disassembly and reassembly of the frequency converter must be done in accordance with the service guide.
Use the standard fastener torque values from the service guide, unless the torque value is specified in these instructions.
WARNING
DISCHARGE TIME (40 MINUTES)
The frequency converter contains DC-link capacitors, which can remain charged even when the frequency converter is not pow-
ered. High voltage can be present even when the warning LED indicator lights are off. Failure to wait 40 minutes after power has
been removed before performing service or repair work can result in death or serious injury.
Stop the motor.
Disconnect AC mains and remote DC-link power supplies, including battery back-ups, UPS, and DC-link connections to other
frequency converters.
Disconnect or lock the motor.
Disconnect any brake option.
Disconnect any DC connector option.
Wait 40 minutes for the DC-link capacitors to discharge fully.
Before performing any service or repair work, measure the voltage level to verify that the capacitors are fully discharged.
WARNING
ELECTRICAL SHOCK HAZARD
The frequency converter contains dangerous voltages when connected to mains voltage. Improper installation, and installing or
servicing with power connected, can cause death, serious injury, or equipment failure.
Only use qualified electricians for the installation.
Disconnect the frequency converter from all power sources before installation or service.
Treat the frequency converter as live whenever the mains voltage is connected.
Follow the guidelines in these instructions and local electrical safety codes.
NOTICE
ELECTROSTATIC DISCHARGE
Electrostatic discharge can damage components.
Ensure electrostatic discharge before touching internal frequency converter components, for example by touching a groun-
ded, conductive surface or by wearing a grounded armband.
2.2 Installation Overview
NOTICE
APPLYING GASKETS
This kit contains self-adhesive gaskets to ensure a proper seal between metal parts.
Before affixing a gasket, check that the part matches the gasket and that no holes are covered.

2.5 Assembling the Ducts
The top and bottom ducts are telescopic ducts that collapse to simplify installation. To assemble the ducts before installation, use
the following steps. Refer to Illustration 7.
Procedure
Cut the strip of ribbed EPDM rubber seal into 4 pieces. Cut 2 strips of 1027 mm (40.4 in) for the top duct, and 2 strips of 990
mm (39.0 in) for the bottom duct.
Peel the paper off the self-adhesive seals. Place 1 strip on the outside bottom edge of the inner sleeve of each duct, and 1
strip on the upper inside edge of the outer sleeve of each duct.
