inverter modules: capacitor
renewal

Checking and replacing the air filters

Before replacing the air filters of the cabinet, read and repeat the steps in the safety
instructions above.

Heatsinks

Heatsink fins pick up dust from the cooling air. Inverter modules run into
overtemperature warnings and faults if the heatsink is not clean. In a "normal"
environment (not dusty, not clean) the heatsink should be checked annually, in a
dusty environment more often.
Clean the heatsink as follows (when necessary):
1. Remove the cooling fan as described in
2. Blow clean, dry compressed air from bottom to top and simultaneously use a
vacuum cleaner at the air outlet to trap the dust. Note: Prevent the dust from
entering adjoining equipment.
3. Refit the cooling fan.
