Powering Up the System
7-3
1.
At this point, the AC power cord should still be unplugged.
2.
Pull down the circuit breaker handle on the AC input box (see Figure
7-1).
3.
At the control panel, make sure the keyswitch is in the Disable posi-
tion.
The circuit breaker controls power to the system. 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.
Current overload causes the circuit breaker to trip to the off position, so
that power to the system is turned off.
