Device failure after a DC fuse trips
The neighboring DC fuses may also become damaged if a DC fuse trips. Failure to replace
all fuses at the same time can cause the device to fail.
• After a DC fuse trips, always replace all DC fuses at the same time. Always use fuses of
the same type.
Note
Replacing a complete power unit
If you order a complete power unit as a replacement, make sure that only DC fuses are
used. If option L37 (DC inte
rface including precharging input circuit) is installed in your
cabinet, the DC fuses of the spare part must be replaced with the copper lugs of the existing
power unit.
