5. To crank and start the engine, set the AUTO/OFF/MANUAL
switch to MANUAL.
6. Let the engine stabilize and warm up for a few minutes.
7. Set the generator’s main circuit breaker to its ON (or CLOSED)
position. The standby power source now powers the loads.

3.4.2 TRANSFER BACK TO UTILITY POWER
SOURCE
When utility power has been restored, transfer back to that source
and shut down the generator. This can be accomplished as fol-
lows:
1. Set the generator’s main circuit breaker to its OFF (or OPEN)
position.
2. Let the engine run for a minute or two at no-load to stabilize
the internal temperatures.
3. Set the generator’s AUTO/OFF/MANUAL switch to its OFF (or
OPEN) position. The engine should shut down.
4. Check that utility power supply to the transfer switch is turned
OFF.
DANGER
Do not attempt to activate the transfer switch
manually until all power voltage supplies to the
switch have been positively turned off. Failure to
turn off all power voltage supplies may result in
extremely hazardous and possibly fatal electri-
cal shock.
5. Use the manual transfer handle inside the transfer switch to
move the main contacts back to their UTILITY position, i.e.,
loads connected to the utility power source (Figure 3.2).
6. Turn ON the utility power supply to the transfer switch using
the means provided.
7. Set the system to automatic operation as outlined in Automatic
Transfer Operation section.
3.5 SIDE COMPARTMENT (V-TWIN ONLY)
(FIGURES 3.4 & 3.5)
Local codes may require this compartment to be locked. A hasp is
provided so the owner can secure the compartment with their own
padlock. Check local codes in the area.
3.5.1 MAIN CIRCUIT BREAKER
This is a 2-pole breaker rated according to the Specifications sec-
tion.
3.5.2 EXTERIOR READY LIGHTS
Green LED ‘Ready’ light (10, 14, 17 & 20 KW) is on when util-
•
ity is present and switch is in AUTO indicating the generator is
ready and when the generator is running.
Red LED ‘Alarm’ light (10, 14, 17 & 20 KW) is on when the
•
generator is OFF or a fault is detected. (See the Protections
Systems section.)
Yellow LED ‘Maintenance’ light (17 & 20 KW) (See the
•
Protections Systems section.)
3.5.3 120 VAC GFCI OUTLET & 15 AMP BREAKER
(17 & 20 KW ONLY)
These models are equipped with an external, 15 amp, 120 volt,
GFCI convenience outlet that is located in a compartment on the
right side of generator (Figure 1.3).
When the generator is running, in the absence of utility power, this
outlet may also be used to power items outside your home such
as lights or power tools. This outlet may also be used when utility
power is present by running the generator in manual mode. This
outlet does not provide power if the generator is not running. This
outlet is protected by a 15 amp circuit breaker in the same com-
partment as the outlet. (Do not use when the generator is running
in exercise mode.)
