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 drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be present even when the warning 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 backups, UPS, and DC-link connections to other drives.
Disconnect or lock the permanent magnet motor.
Wait for the capacitors to discharge fully. The minimum waiting time is 40 minutes.
Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors are fully discharged.

WARNING ELECTRIC SHOCK HAZARD
AC drives contain dangerous voltages when connected to mains voltage. Installing or servicing the drive with power connected can cause death, serious injury, or equipment failure.
Only use qualified electricians for the installation. Disconnect the drive from all power sources before installation or service. Treat the drive as live whenever the mains voltage is connected. Follow the guidelines in these instructions and local electrical safety regulations.
NOTICE ELECTROSTATIC DISCHARGE
Electrostatic discharge can damage components. Follow standard ESD procedures. Ensure discharge before touching internal components, for example by touching a grounded, 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.
