Data sheet

FUSE Mode

Operating and environmental data

The FUSE Mode (electronic fuse in the output) protects the unit from

overload and overtemperature. The FUSE Mode acts as a fuse for the

secondary side and protects cables and slaves.

Shutdown:

• At overtemperature, overload or short-circuit, the unit switches off

the output after 2...5s.

Indicator:

• Activation of the FUSE Mode is indicated by a flashing red LED.

Reset/Restart:

• by intentionally pushing the Reset button on the unit front panel

• by turning off the mains voltage. Before restarting the unit, wait at

least twice the time the flashing red LED needed to extinguish after

the mains voltage dropped.
