Disconnecting Set from Vehicle Systems
Disconnect the following items from the genset. Re-
fer to Figures 5-1 and 5-2 on Page 5-3 for compo-
nent locations in typical genset installations.
Some installations may require partial removal of
the set to gain access to the battery cable, fuel line
and other connections. Read this section before
starting set removal.
1. Disconnect the vehicle negative (–) battery
cable at the battery terminal.
WARNING
Sparks and high current could
cause fire and other damage to the battery,
battery cables and vehicle if the loose ends
of cables connected to the battery touch.
Always disconnect the negative (–) battery
cable from the battery before disconnect-
ing the battery cables from the genset.
2. Remove the genset negative (–) battery cable
at the battery terminal.
3. Disconnect the genset positive (+) battery
cable from the B+ connection on the genset.
4. Disconnect the remote control wire connector
from the left side of the genset housing.
5. Disconnect the generator load wires from in-
side the genset. Remove the control assembly
mounting bracket (Figure 6-1 on Page 6-2 or
Figure 6-2 on Page 6-3). Raise the control as-
sembly and disconnect the ground and neutral
(L2) lead from the ground terminal. Disconnect
the inline load (L1) lead connection. Tag the
wires for identification when reconnecting.
6. Loosen the conduit connector elbow, and pull
the load wires and flexible conduit free of the
genset.
7. Disconnect the exhaust tail pipe from the gen-
set. Disconnect any exhaust support brackets
or hangers that restrict removal of the genset.
8. Disconnect the fuel line from the genset. Follow
the applicable instructions depending on the
fuel.
A.
Gasoline-fueled Gensets:
Disconnect
the fuel line from the genset and securely
plug the end of the fuel line to prevent leak-
age or an accumulation of explosive gaso-
line vapor.
B.
LPG-fueled Gensets:
Close the fuel shut-
off valve(s) at the LPG container(s) and
move the vehicle outside and away from
below-grade spaces where LPG could ac-
cumulate. To purge most of the LPG from
the fuel line and genset, run the genset (if
it starts) until it runs out of fuel (LPG con-
tainer valve closed). To purge some of the
remaining LPG, press the regulator primer
plunger (Figures 8-18 and 8-19 on Pages
8-22 and 8-23) while cranking the engine
for 10 seconds. Disconnect the fuel line
from the genset and plug the end of the
hose to prevent fuel from escaping if
someone inadvertently opens the shutoff
valve(s) at the LPG container(s).
WARNING
Gasoline and LPG (liqui-
fied petroleum gas) are flammable and
explosive and can cause severe per-
sonal injury or death. Do not smoke.
Keep flames, sparks, pilot lights, arc-
producing and switching equipment,
and all other sources of ignition away
from fuel tank and system, and areas
sharing ventilation. Have an ABC fire
extinguisher handy.
WARNING
LPG is flammable and ex-
plosive and can cause asphyxiation.
NFPA 58, Section 1.6 requires all per-
sons handling LPG to be trained in
proper handling and operating proce-
dures.
LPG “sinks” and can accumulate in ex-
plosive concentrations. Before discon-
necting the LPG fuel line, close the fuel
shutoff valve(s) at the LPG container(s)
and move the vehicle outside and away
from pits, basements, and other below-
grade spaces where LPG could accu-
mulate.
