may result if you fail to observe all safety precautions.
Lethal voltages are present in the Power Supply. Perform the following steps to
eliminate electrical shock hazard. Make sure external power is turned OFF before
performing any maintenance procedures.
1. Turn the power to the IS-2200CA Power
Supply to the off position by rotating the
handle located on the front door to the
OFF position.
2. Open the front door by turning the three
quarter-turn screws.
3. The capacitors will automatically
discharge in about 30 seconds. If the
Charge Indicator is lit (see illustration to
the right), then the IS-2200CA contains
lethal voltages. DO NOT service until
the lamp is off and at least 30 seconds of
time have lapsed.
NOTE: If necessary for maintenance, remove the Safety Shields by removing the five screws
used to secure the Capacitor cover or the four screws used to secure the Circuit Breaker cover.
