WARNING
DISCHARGE TIME
The frequency converter contains DC-link capacitors,
which can remain charged even when the frequency
converter is not powered. High voltage can be present
even when the warning LED indicator lights are off.
Failure to wait the specified time 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 PM motor.
•
Wait at least 4 minutes for the capacitors to
discharge fully.
•
Before performing any service or repair work,
use an appropriate voltage measuring device to
make sure that the capacitors are fully
discharged.
CAUTION
RISK OF INJURY OR PROPERTY DAMAGE
Do not assume that a motor is wired properly after
completed service of the frequency converter.
Check for:
•
Loose connections.
•
Improper programming.
•
Added equipment.
Failure to perform these checks can result in personal
injury, property damage, or less than optimal
performance.
WARNING
REPAIR WORK
In the event of an error, alarm or warning, refer to
chapter 7 Troubleshooting. Before commencing repair
work, contact Danfoss Service.
NOTICE
PELV COMPLIANCE
All control terminals and relay terminals 01-03/04-06
comply with PELV (Protective Extra Low Voltage).
However, in grounded delta configuration above 400 V,
the frequency converter is not PELV-compliant.
