2 Installation
2.1 Safety Information
NOTICE
QUALIFIED PERSONNEL
Only qualified 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 corresponding service guide.
Use the standard fastener torque values from the service guide, unless the torque value is specified in these instructions.
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 regulations.
WARNING
DISCHARGE TIME (20 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 indicator lights are off.
Failure to wait 20 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, permanent magnet type motors, and remote DC-link supplies, including battery backups, UPS, and
DC-link connections to other frequency converters.
Wait 20 minutes for the capacitors to discharge fully before performing any service or repair work.
To verify full discharge, measure the voltage level.
NOTICE
ELECTROSTATIC DISCHARGE
Electrostatic discharge can damage components.
Ensure discharge before touching internal frequency converter components, for example by touching a grounded, conduc-
tive 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.
