The control power supply on 2094-AL09 and 2094-BL02 line interface modules
is protected by one 3-pole circuit breaker (CB2).
They all have a single-phase filter placed in the control VAC supply to provide
protection/conditioning. For safety reasons, the internal wiring is arranged so
that, if the control power (CPL) circuit breaker (CB2) trips, the opening contact
will interrupt the coil voltage. Circuit breaker CB2 and fuse block FB1 are
field-replaceable.
For FB1 replacement fuse part numbers, see the table on
page 50
.
