10.1 Preventive Maintenance Recommendations
Generally, all technical equipment, including iC7 Series Cooling Modules, need a minimum level of preventive maintenance. Regular
maintenance is recommended to ensure trouble-free operation and long life of the cooling module. It is also recommended, as a
good service practice, to record a maintenance log with counter values, date, and time describing the maintenance and service
actions.
Danfoss recommends the following inspections and service intervals for the cooling module.
The service schedule for part replacements can vary depending on operation conditions. Under specific conditions, the combina-
tion of stressful operating and environment conditions work together to reduce the lifetime of the components significantly.
These conditions can include, for example, extreme temperature, dust, high humidity, hours of use, corrosive environment, and
loading.
For operation in stressful conditions, Danfoss offers the DrivePro
lifetime and increase the performance of the product with scheduled maintenance including customized part replacements. Drive-
Pro services are tailored to your application and operating conditions.

(2)
– Check for the unusual, for example, for signs of overheating, aging, corrosion,
and for dusty and damaged components.
According Inspect equipment, switchgear, relays, disconnects, or fuses/circuit breakers. Ex-
to manu- amine the operation and condition for possible causes of operational faults or
facturer defects. The continuity check on fuses must be performed by trained service per-
recommen- sonnel.
dations
– Inspect the installation wiring regarding the electromagnetic capability and the
separation distance between control wiring and power cables.
– Check for parallel routing of motor cables, mains wiring, and signal wiring. Paral-
lel routing must be avoided. Avoid routing cables through free air without sup-
port. Check for aging and wearing of the cable insulation.
– Check for tightness, damaged or crimped wires or ribbon wires. The connections
must be terminated correctly with solid crimped ends. The use of shielded cables
and grounded EMC plate, or a twisted pair is recommended.
– Check that the required external clearances for proper air flow for cooling are fol-
lowed. For clearances, refer to the local design regulations.
– Check that the seals of the enclosure, the covers, and the cabinet doors are in
good condition.
– Conductive dust and aggressive gases, such as sulphide, chloride, and salt mist,
can damage the electrical and mechanical components. Air filters do not remove
air-borne corrosive chemicals. Act based on findings.
– Check that the parameter settings are correct according to the motor, and I/O
configuration. Only trained service personnel can perform this action.
