Fuse Replacement

Fuses are accessed by removal of the appropriate panel, as described in the 'Panel
Removal' section. Depending on the model, supply fuses and control circuit fuses may
be mounted in their own holders, or may be on a circuit board that contains an EMC
filter. The fuses are marked with their ratings.

Take care not to disconnect the wires leading from the EMC filter without first recording
their positions: they must be reconnected to the correct terminals.
