MAINTENANCE AND SERVICING PROCEDURES General
WARNING! All equipment maintenance and servicing procedures involve internal
access and should be carried out only by trained personnel on a de-energized system.
Extreme caution is required when performing maintenance and servicing procedures.
Be constantly aware that this system contains high DC as well as AC voltages. Check
for voltage with both AC and DC voltmeters prior to making contact.
Special safety precautions are required for procedures involving maintenance of this
system and the batteries. Observe all safety precautions in this manual and in the
battery instruction manual before as well as during performance of all maintenance
procedures. Observe all battery safety precautions before working on or near the
batteries. Service personnel and test equipment should be standing on rubber mats.
Service personnel should wear insulating shoes for isolation from direct contact with
the floor (earth ground).
This equipment contains several circuits that are energized with dangerous voltage.
Only test equipment designed for troubleshooting should be used. This is particularly
true for oscilloscopes. Always check with an AC and DC voltmeter to ensure safety
before making contact or using tools. Even when the power is turned OFF,
dangerously high electric charges may exist within the system.
Never work alone, even if all power is removed from the equipment. A second person
should be standing by to assist and summon help in case an accident should occur.
Dual Hazardous Input Power Sources
WARNING! The system may be powered from dual hazardous input power sources
simultaneously: Commercial AC and Battery DC. Disconnect both sources of power
before servicing.
WARNING! Installation or removal of the circuit cards requires careful handling.
Before handling any circuit card, read and follow the instructions contained on the
