Cooling Fan; Capacitors - Salicru CV10-002-S2 User Manual

6.1.2 Cooling fan

The inverter's cooling fan has a minimum life span of 25,000 operating hours. The actual life span depends on
the inverter usage and ambient temperature.
The operating hours can be found through P07.14 (accumulative hours of the inverter).
Fan failure can be predicted by the increasing noise from the fan bearings. If the inverter is operated in a critical part of a
process, fan replacement is recommended once these symptoms appear. Replacement fans are available from SALICRU.
 Read and follow the instructions in chapter Safety Precautions. Ignoring the
instructions would cause physical injury or death, or damage to the equipment.
1. Stop the inverter and disconnect it from the AC power source and wait for at least the time designated on the
inverter.
2. Lever the fan holder off the drive frame with a screwdriver and lift the hinged fan holder slightly upward from
its front edge.
3. Disconnect the fan cable.
4. Remove the fan holder from the hinges.
5. Install the new fan holder including the fan in reverse order. Keep the wind direction of the fan consistent with
that of the inverter, as shown below:
6. Restore power.

6.1.3 Capacitors

Reforming the capacitors
The DC bus capacitors must be reformed according to the operation instruction if the inverter has been stored
for a long time. The storing time is counted from the producing date other than the delivery data which has been
marked in the serial number of the inverter.
Time
Storing time less than 1 year
Storing time 1-2 years
Storing time 2-3 years
