utility power is restored, the system reconnects utility
power to the transfer switch, lets the engine 'cool down',
shuts off the generator, and waits for the next utility
power outage.
• "OFF" position turns off a running generator and takes
the system out of the Automatic operation mode.
• "MANUAL" position starts the engine but does not
disconnect utility power from the transfer switch. It is
used for maintenance or diagnostic functions.
15 Amp Fuse
The Home Generator System DC control circuit is
protected from overload by a 15 Amp fuse mounted on the
generator's control panel (see Figure 16).The fuse is wired
in series with the battery output lead to the control panel.
TO THE INSTALLER: This system is designed so
that when Utility power is present and the 15 Amp
fuse is blown or missing, the transfer switch
UTILITY relay remains closed, thus providing utility
power to the customer.The generator will not start
if utility power drops out or the 15 Amp fuse is
blown or missing.
These functions are controlled by the CMA board. It
provides the power needed to hold the transfer switch
UTILITY relay closed for as long as there is a charge in the
starting battery AND utility power is present
REGARDLESS of the absence or presence of the 15 Amp
fuse.
Replace the fuse using ONLY an identical BUS AGC
15A fuse. One spare fuse is supplied with the unit.
BEFORE INITIAL ENGINE
START -UP
Engine Oil
The generator's engine is shipped from the factory full of
oil and should be ready to run. However, check oil level and
ensure that engine is serviced as described in the Engine
Owner's Manual.
CAUTION!
Any attempt to crank or start the engine
before it has been properly serviced with the
recommended oil will result in an engine failure that is not
covered under warranty.

Oil Considerations
Your Home Generator System is equipped with an engine
that has completed the traditional "break-in" process.The
engine should only be filled with synthetic oil (SAE 5W-30,
API SJ or later).This permits 'standby' operation in the
widest range of temperature and climate variations.
NOTE: The use of synthetic oil does not alter the
required oil change intervals recommended in the Engine
Owner's Manual.
Battery Connection
The Home Generator System is supplied with a 12 Volt DC
18 Amp-Hour battery. It is a sealed, lead-acid rechargeable
battery. It is installed in the unit and the battery cables are
connected at the factory.The unit's 15 Amp fuse, which
isolates the battery and prevents the unit from starting, has
been removed for shipping.
If it is necessary to connect the battery, proceed as follows:
1.
Set the generator's "AUTO/OFF/MANUAL" switch to
OFF.
2.
Turn OFF the main distribution panel circuit breaker
supplying utility power to the Automatic Power
Transfer System.
CAUTION!
The generator can crank and start
when the battery cable contacts the battery
terminal if the "AUTO/OFF/MANUAL" switch is not
set to its OFF position.
3.
Using supplied hardware, connect the red battery lead
to the battery positive terminal (indicated by
POSITIVE, POS, or (+).
4.
Repeat step 3 (above) to connect the negative battery
cable.You may need to clip a cable tie to place the
negative wire. Ensure hardware on both positive and
negative battery terminals is secure.
NOTE: With the battery installed and utility power available
to the Automatic Transfer Switch, the battery receives a
trickle charge whenever the engine is not running.The trickle
charge only prevents self-discharge and cannot be used to
recharge a battery that is completely discharged.
Fuel Supply System
Ensure that all fuel pipe connections are tight, secure and
without leaks.
NOTE: In the absence of local purging and leak test
standards, NFPA No. 54 may be used as a guide. (See
"Standards Index" on page 19).
