7.3 Fuses and Overcurrent Protection
WARNING
-
HIGH VOLTAGE
Always isolate your controller at source before you open the unit to inspect
it or replace fuses.
CAUTION
If any fuse has ruptured, it must be replaced with a new one with identical
characteristics.
CAUTION
The modular circuit breaker (MCB) o󰀨ers general over-current protection and
there are fuses for various sub-circuits. Of the two rear panel-mounted fuses,
one protects the cooling fans and the second protects the internal back-plane
distribution which feeds the individual cards.
The tables under each heading in the following sections show the correct
fuse type.
7.3.1 Fans
If any fan has stopped working, rst inspect the unit to see if there are any
blockages or objects fouling the impellers. If the fan is free to rotate, then
check the panel-mounted fuse at the rear of the unit.
