Electrician must remove (3) cap screws (see arrows) 
and slide panel down 2 inches, then pull straight out 
for complete removal. At this point, high voltage 
wiring terminals are exposed. Replace panel by 
positioning it 2” under roof, sliding it upwards until it 
stops, then replacing (3) cap screws. 
 
The high voltage access panels should only 
be removed by experienced licensed 
electricians, repair and service personnel, 
and installers. 
Electrical
shock
from
mishandled
battery.
Toxic fumes from battery or engine
exhaust may be inhaled.
Hot surfaces may cause severe burns.
Explosions from battery or dry fuel
fumes being ignited by careless smoking or
sparks from mishandled tools.
At engine end, behind bolted panel 
contains 
dangerous
high
voltage
electricity. These voltages can cause a
fatal electric shock and will cause sudden illness, 
dizziness, and incoherent actions. Only experienced 
licensed 
electricians
and
authorized
service
technicians should have access to this high voltage 
area. 
 
The 12 VDC battery is not furnished with the standby 
generator set. The generator can be installed in a 
wide range of temperatures and climate conditions. 
As climates get colder, batteries loose their ability to 
produce required power. Therefore, battery size 
must be increased. 
 
Climates that reach to a low of 30º F (-1.1 º C) can 
achieve good generator operation with a 12 VDC, 45 
amp hour battery. Climates that reach below this 
temperature line should have a 55 amp/hour 12 VDC 
battery. 
 
CAUTION: All 12 VDC batteries will loose a certain 
percent of their charge while in storage. It is very 
important to test the battery voltage before it is 
installed in generator and taken to jobsite. A fully 
charged battery must test at 12.5 – 13.0 volts DC. 
Also, the correct battery for models SPS-120 and SPP-
180 must have lug terminals to match lug battery 
cables, for a bolt-together connection. 
 
This generator is equipped with a battery tray, a 
battery hold down strap and battery cables. Place the 
selected fully charged battery with full electrolyte in 
battery tray and secure with battery hold down 
clamp. 
 
Before connecting battery cables to battery, complete 
the following steps: 
 
1) Set the generator’s toggle switch to “OFF” position. 
Remove the 20 amp fuse near the remote start/stop 
terminal block (labeled “S” & “+”) on the back panel 
of the control circuit (see these locations at “Know 
Your Systems Control Panel” on page 11). 
 
2) Turn off utility power supply to the previously 
installed automatic transfer switch. 
 
3) Battery cables are factory connected at the 
generator points. Electrician should connect the red 
battery cable (from engine starter solenoid point) to 
battery post shown with “positive”, POS, or (+) 
indicator. Connect the black battery cables (from 
frame ground) to the battery. 
DANGER
BATTERY SELECTION & INSTALLATION
WARNING
FOR LICENSED ELECTRICIAN’S USE, ONLY
When hinged door on generator end of housing is un
-locked and opened, the control panel is exposed. 
(see item 1, 8 point diagnostic display panel on page 
11). An access panel, for electrician’s use only, is 
located at top of hinged door access.
