CAUTION
✸
Ten thermal circuit breakers are located on the
front of the E1135B/C PDU. These circuit
breakers are designed to protect the loads on the
output terminal block. Under normal operation, if
an overload occurs, the rocker on the breaker will
pop to the open position. The rocker can be reset
by pushing it gently back in place. It is necessary
to wait a few minutes for the breaker to cool
before this can be done. A breaker which cannot
be reset may be permanently damaged by a
short-circuit at the load.
These breakers are not switches and must not be
opened by force. If opened by force, permanent
damage will result. Damage caused by
intentionally opening the breaker is not covered
by warranty.
The electrician should use the Full Load Amps (FLA) in
on page 10-84 for 3-phase and
on page 10-86 for single-phase systems to determine the
conductor size to the power receptacle where the SO
Cord, or service mains, will connect. Then use the
sections
Sizing The Input Wires And Circuit
on page 10-90 to determine the SO Cord
size and breaker size.
