If only one power supply module is used, mask the fault for the unused power supply as follows:
Step Task

2 Select to mask the unused power supply.
The power supplies contain two fuses, one each for line and neutral connections
(or L1, L2 where appropriate). These are contained within the body of the
connector, behind the small plastic flap.
For continued operator safety, always replace the fuses with the correct type and
rating. For 115/230 volt AC operation, use T1A (slow‐blow) 20 mm fuses.
