The circuit breaker and power indicators are at the rear of the cabinet.
Circuit Breaker
The circuit breaker controls power to the entire system, including the
power regulators, blower, battery backup, and in-cabinet options. Current
overload causes the breaker to trip to the off position, so that power to the
system is turned off.
For normal operation, the circuit breaker must be in the on position, in
which the handle is pushed up. To shut the circuit breaker off, push the
handle down.
AC Power Indicators
The power indicators are located below the circuit breaker handle. When
the system is powered on, the power indicators are red. When the circuit
breaker is off, tripped, or open, the power indicators change to green.
When one phase has tripped, the power indicator for that phase will
change to green.
NOTE: The power indicators in the 202V version are different. If one phase
trips, all power indicators trip, so that all indicators are green.
Circuit Breaker Lockout
The circuit breaker lockout secures the circuit breaker in the off position.
The lockout consists of a hinged plate that is placed over the circuit
breaker handle. A padlock can be placed on the right or left side of the
lockout, so that no one can turn the power on.
Controls and Indicators 3-7
