DANGER
Grounding
The frame ground leads must be connected before any
other leads. This is to prevent the cabinets and any other
metal structures from carrying dangerous ac or dc voltage
levels.
DANGER
Protecting against electrical shocks
The cabling of the power plant, and all other required
cabling, must be carried out by qualified personnel and in
conformance with local and national electrical codes. AC
input voltages to the rectifiers are at a dangerous level.
Ensure that the circuit breakers are locked in the OFF
position in the ac service panel before working on the
power plant. Dangerous voltages may be present at the
output dc terminals even if the rectifiers are OFF. Use a
voltmeter to verify for the presence of such voltages. Do
not put the circuit breakers to ON until the entire system
has been assembled and you have been instructed to do so.
Verify, and identify with a tag, the proper polarity of the
battery leads before connecting them to the power plant.
