Installation Procedures
8
Disconnect power sources before servicing.
Barrier must be installed after adjustments,
maintenance, or servicing.
WARNING
Hazardous voltage.
Can cause severe injury or death.
(under 600 Volt)
Hazardous voltage can cause severe
injury or death.
The transfer switch is
energized; proceed with care! High voltage
can
cause
personal
injury,
damage
equipment, or lead to future failures. Remove
watch, rings, and jewelry that can cause short
circuits.

DANGER
Hazardous voltage.
Will cause severe injury or death.
(600 Volt and above)
Hazardous voltage will cause severe injury
or death.
The transfer switch is energized;
proceed with care! High voltage will cause
personal injury, damage equipment, or lead to
future failures. Remove watch, rings, and
jewelry that can cause short circuits.
Voltage Checks
6. Close the normal source circuit breaker.
7. Use an accurate voltmeter to check for
proper voltage and phase rotation
(phase-to-phase and phase-to-neutral
voltages) at the contactor’s normal-source
terminals.
8. Close the emergency-source circuit
breaker.
9. Manually start the generator set using the
engine control switch on the generator set
controller.
10.Use an accurate voltmeter to check for
proper voltage and phase rotation
(phase-to-phase and phase-to-neutral
voltages)
at
the
contactor’s
emergency-source terminals.
11. If necessary, adjust the generator voltage
regulator following the generator set
manufacturer’s instructions. Check phase
rotation; it should be the same as that of
the normal source.
12.Shut down the generator set using the
engine control switch on the generator set
controller.
