4.1 Safety Considerations
WARNING
Hazardous Voltage
Contact with high voltages can cause severe electrical shock, burns, or
death.
Make sure that only personnel who are trained and qualified to work on this
equipment are allowed to operate the generator set and perform
maintenance on it.
WARNING
Automated Machinery
Accidental or remote starting of the generator set can cause severe personal
injury or death.
Make sure that the generator set cannot be started accidentally or remotely
before starting work on the generator.
WARNING
Combustible Gases
Ignition of battery gases is a fire and explosion hazard which can cause
severe personal injury or death.
Do not smoke, or switch the trouble light ON or OFF near a battery. Touch a
grounded metal surface first before touching batteries to discharge static
electricity. Stop the generator set and disconnect the battery charger before
disconnecting battery cables. Using an insulated wrench, disconnect the
negative (–) cable first and reconnect it last.
CAUTION
Hazardous Voltage
Contact with high voltages can cause severe electrical shock, burns, or
death.
Isolate all external electrical supplies prior to access of the control panel.
Internal components have live exposed terminations even when the
generator set is not running.
NOTICE
Always disconnect a battery charger from its AC source before
disconnecting the battery cables. Failure to do so can result in voltage
spikes high enough to damage the DC control circuits of the generator set.
