Only certified technicians trained by Danfoss are allowed to replace the parts described in these installation instructions.
Installation work done by non-qualified personnel can result in personal injury or equipment damage. Make sure to read and save these instructions.
WARNING
ELECTRICAL SHOCK HAZARD
VLT
®
frequency converters contain dangerous voltages when connected to mains voltage. Improper installation, and installing or servicing with power connected, can cause death, serious injury, or equipment failure.
To avoid 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.
WARNING
DISCHARGE TIME
The frequency converter contains DC-link capacitors, which can remain charged even when the unit is off. High voltage can be present even when the warning indicator lights are off. Failure to wait a minimum of 20 minutes after power is removed before performing service work can result in death or serious injury.
1.

4.
5.
Stop the motor.
Disconnect AC mains and remote DC-link supplies, including battery back-ups, UPS, and DC-link connections to other frequency converters.
Disconnect or lock PM motor.
Wait 20 minutes for the capacitors to discharge.
To verify full discharge, measure the voltage level.
NOTICE
The current sensor kit includes an extra set of fasteners in case any fasteners are missing or unusable. To make the disassembly/reassembly process easier, use these general guidelines:

5.
Follow the disassembly instructions for each component.
Place the component along with the removed fasteners together in one place.
Replace old component with the new component provided in the kit.
If any fasteners are stripped or lost, replace with similar fastener from the kit.
Follow the installation instructions for replacing and securing each component.
