Basic troubleshooting.
Under normal operating conditions and load profiles, the

To prevent breakdown, danger, and damage, examine the
drive at regular intervals depending on the operating
conditions. Replace worn or damaged parts with original
spare parts or standard parts. For service and support, refer
to www.danfoss.com/contact/sales_and_services/.
WARNING
UNINTENDED START
When the drive is connected to AC mains, DC supply, or
load sharing, the motor can start at any time.
Unintended start during programming, service, or repair
work can result in death, serious injury, or property
damage. The motor can start with an external switch, a
fieldbus command, an input reference signal from the
LCP or LOP, via remote operation using MCT 10 Set-up
Software, or after a cleared fault condition.
To prevent unintended motor start:
•
Press [Off/Reset] on the LCP before
programming parameters.
•
Disconnect the drive from the mains.
•
Completely wire and assemble the drive, motor,
and any driven equipment before connecting
the drive to AC mains, DC supply, or load
sharing.

8.2 Heat Sink Access Panel

The drive can be ordered with an optional access panel in
the back of the unit. This access panel provides access to
the heat sink and allows the heat sink to be cleaned of any
