Input Circuit Breaker
The following instructions apply to all input circuit breakers.
The main power switch is typically the input circuit breaker located on the rear
panel in the standard configuration. However, the front panel switch can be
used to power down the unit. This switch is wired in series with the rear panel
circuit breaker. To avoid shock hazard, turn off both the power supply switch
and the circuit breaker.
Removing/Replacing the input circuit breaker
1. Turn off the main system power.
2. Disconnect the power cord/cable.
3. Remove the four screws that mount the breaker plate to the rear panel.
4. Gently pull the breaker plate away from the rear panel until the circuit
breaker and the quick-disconnect terminals can be easily accessed.
5. With the wires still connected, squeeze the spring clips on the sides of
the old circuit breaker, pushing it through the front of the breaker plate
until it pops out the front of the plate.
6. Removing the wires, one by one from the old circuit breaker, attach
each one to the new circuit breaker, placing it on the correct terminal.
7. Push the new circuit breaker back into position in the breaker plate
until the spring clips on the breakers side snap into place.
8. Re-install the plate.
9. Plug in the power cord or reinstall the power cable.
10. Turn on the main system power.
