Post Installation Start-up and Adjustments

2.1

ACTIVATE THE GENERATOR

When battery power is applied to the generator during the installa-
tion process, the controller will light up. However, the generator still
needs to be activated before it will automatically run in the event
of a power outage.
Activating the generator is a simple one time process that is guided
by the controller screen prompts. Once the product is activated,
the controller screen will not prompt you again, even if you discon-
nect the generator battery.
After obtaining your activation code, please complete the following
steps at the generator's control panel in the Activation Chart.
2.2 BEFORE INITIAL START-UP
These units have been run and tested at the factory prior to
being shipped and do not require any type of break-in.
This unit comes filled with oil from the factory. Check the oil
level and add the appropriate amount if necessary.
Before starting, complete the following:
1. Set the generator's main circuit breaker to its OFF (or OPEN)
position.
2. Set the generator's AUTO/OFF/MANUAL switch to the OFF
position.
3. Turn OFF all breakers on the load center of the transfer box (T1
and T2).
4. Turn OFF all loads connected to the transfer switch terminals
T1 and T2.
5. 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.
6. 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 "over crank" fault (See
the "Overcrank" section). This is due to accumulated air in the fuel
system during installation. Reset the control board and restart up
to two more times, if necessary. If unit fails to start, contact the
local dealer for assistance.
Never operate the engine with the oil level
below the "Add" mark on the dipstick. Doing
this could damage the engine.

NOTE:
NOTE:
2.3 CHECK TRANSFER SWITCH
OPERATION
Refer to the "Manual Transfer Operation" section, of the owner's
manual for procedures.
 Do not attempt manual transfer switch opera-
tion until all power voltage supplies to the
transfer switch have been positively turned
off. Failure to turn off all power voltage sup-
plies will result in extremely hazardous and
possibly fatal electrical shock.
2.4

ELECTRICAL CHECKS

Complete electrical checks as follows:
1. Set the generator's main circuit breaker to its OFF (or OPEN)
position.
2. Set the generator's AUTO/OFF/MANUAL switch to the OFF
position.
3. Turn OFF all breakers on the load center of the transfer box (T1
and T2).
4. Turn on the utility power supply to the transfer switch using
the means provided (such as a utility main line circuit break-
er).
 The transfer switch is now electrically
"hot." Contact with "hot" parts will result in
extremely hazardous and possibly fatal
electrical shock. Proceed with caution.
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.
6. Check utility power source voltage across terminals N1 and
the transfer switch neutral lug; then across terminal N2 and
neutral. Nominal line-to-neutral voltage should be 120 volts
AC.
7. When certain that 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, set the Auto/Off/ Manual switch to
MANUAL. The engine should crank and start.
9. Let the engine warm up for about five minutes to allow inter-
nal temperatures to stabilize. Then, set the generator's main
circuit breaker to its ON (or closed) position.

Proceed with caution! Generator power volt-
age is now supplied to the transfer switch.
Contact with live transfer switch parts will
result in dangerous and possibly fatal electri-
cal shock.
