Before Starting, Complete The Following; Setting The Exercise Timer; Check Manual Transfer Switch Operation; Electrical Checks - Generac Power Systems PowerPact 7.5 kW Installation Manuallines

Before starting, complete the following:

1. Verify generator is OFF.
2. Set the generator main circuit breaker to OFF or
OPEN.
3. Turn off all breakers to be powered by the
generator.
4. Check the engine crankcase oil level and, if
necessary, fill to the dipstick FULL mark with the
recommended oil. Do not fill above the FULL mark.
5. Check the fuel supply. Gaseous fuel lines must
have been properly purged and leak tested in
accordance with applicable fuel-gas codes. All fuel
shutoff valves in the fuel supply lines must be
open.
During initial start up only, the generator may exceed the
normal number of start attempts and experience an
"OVERCRANK" fault. This is due to accumulated air in
the fuel system during installation. Reset the control
board by pushing the OFF button twice, and restart up to
two more times if necessary. If unit fails to start, contact
an Independent Authorized
assistance.

Setting The Exercise Timer

This generator is equipped with an exercise timer. Once
set, the generator will start and exercise every seven
days, on the day of the week and at the time of day
specified. During this exercise period, the unit runs for
approximately 12 minutes and then shuts down. Transfer
of loads to the generator output does not occur during the
exercise cycle unless utility power is lost.
NOTE: The exercise timer does not correct for Daylight
Savings Time.
NOTE: The exerciser will only work in the AUTO mode,
and will default to exercise weekly at the time the Control
Panel was last powered on, unless this procedure is
performed. The exercise function will need to be reset
every time the 12 volt battery and T1 power to the
generator are disconnected and then reconnected, and/
or when the fuse is removed and T1 power is removed
from the generator.
1. Place the generator in the AUTO mode.
2. Hold the SET EXERCISE Button for 3 seconds.
The generator will start, run an exercise cycle, and
confirm the setting. The exercise time must be
established at the time you wish the exercise to
take place.
3. The exercise time is now established. The
generator will exercise each week at this time.
To CHANGE the exercise time once it has been set, hold
the SET EXERCISE button on the generator for three (3)
seconds at the time you wish the new exercise time to
take place.

Check Manual Transfer Switch
Operation
Refer to the "Manual Transfer Operation" section of the
Owner's Manual for procedures.
DANGER
Electrocution. Do not manually transfer under load.
Disconnect transfer switch from all power sources
prior to manual transfer. Failure to do so will result
in death or serious injury, and equipment damage.

Electrical Checks

DANGER
Electrocution. High voltage is present at
transfer switch and terminals. Contact with live
terminals will result in death or serious injury.
Complete electrical checks as follows:
1. Verify generator is OFF.
2. Set generator main circuit breaker to OFF or
OPEN.
3. Turn OFF all circuit breakers/electrical loads to be
supplied by the generator.
4. Turn on the utility power supply to the transfer
switch using the means provided (such as a utility
main line circuit breaker).
5. Use an accurate AC voltmeter to check utility
power source voltage across transfer switch
terminals N1 and N2. Nominal line-to-line voltage
should be 240 volts AC. If voltage is not correct,
verify AC output and wiring from utility source to N1
and N2 lugs at transfer switch.
6. Check utility power
terminals N1 and the transfer switch neutral lug;
then across terminal N2 and neutral. Nominal line-
to-neutral voltage should be 120 volts AC (if wired
with a neutral). If voltage is not correct, verify AC
output and wiring from utility source to N1 and N2
lugs at transfer switch.
7. When certain utility supply voltage is compatible
with transfer switch and load circuit ratings, turn
OFF the utility power supply to the transfer switch.
8. On the generator panel, push the MANUAL button.
The engine should crank and start.
9. Let the engine warm up for about five minutes to
allow internal temperatures to stabilize. Then, set
the generator main circuit breaker to ON or
CLOSED.
