Operating Guide

6 Maintenance, Diagnostics and Troubleshooting

6.1 Maintenance and Service

Under normal operating conditions and load profiles, the drive is maintenance-free throughout its designed lifetime. To prevent
breakdown, danger, and damage, examine the drive for loose terminal connections, excessive dust buildup, and so on, at regular
intervals. Replace worn or damaged parts with Danfoss authorized parts. For service and support, contact the local Danfoss suppli-
er.
UNINTENDED START
When the drive is connected to the AC mains, DC supply, or load sharing, the motor may start at any time, causing risk of death,
serious injury, and equipment or property damage. The motor may start by activation of 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 condi-
tion.
-
Press [Off] on the LCP before programming parameters.
-
Disconnect the drive from the mains whenever personal safety considerations make it necessary to avoid unintended motor
start.
-
Check that the drive, motor, and any driven equipment are in operational readiness.

6.2 Cleaning

The enclosure (IP66/NEMA type 4x indoor) provides protection against dirt and water ingress. The enclosure is suitable for cleaning
methods and solvents used in food and beverage plants. Use the solvent concentration recommended by the manufacturer. Avoid
high-pressure hot water cleaning at close proximity or of long duration, because this method of cleaning can damage gaskets and
labels.

6.3 Frontal LEDs

The actual status can be read via 6 LEDs, which signal the actual status of the unit.
