The fuses on this module are merely
supplementary fuses. External overcurrent
protection (suitable for branch circuits conforming
to the local regulations for electrical engineering)
is required in the supply cables of the load circuit.
Potential errors are:
- No load voltage
- Fuse defective
- Output overloaded
If an overload condition is detected, the output is
inhibited for approximately 2.4 s.
