Frame Ground Connection
WARNING: Be sure the system is properly grounded before applying power. Do not apply AC power
before you ensure that grounds are connected. Electrical shock can cause serious or fatal
injury. NEC requires that the frame and exposed conductive surfaces (metal parts) be
connected to an approved earth ground. Local codes may also require proper grounding of
generator systems.
It is important for safety reasons that the Generator set, transfer switch and battery charger share
a common Ground and neutral.
The NEC requires that the frame and exposed metal surfaces be at local ground reference
potential to avoid electrical shock hazard. A local ground reference may require a driven earth
ground conductor at the generator installation site. Make the ground connection as shown in
Figure 3-11. Use the appropriate size wire as required by NEC and local codes.

1. Open the enclosure access panel door 2 ( Figure 3-1).
2. Connect the ground wire to the “earth ground” terminal shown in Figure 3-11.
This ground is the local reference ground to ground the generator frame only.
Engine Oil Level
AE8, AE10, AE11, and AE25
These generators are shipped dry, which means there is no oil in the engine and no battery
installed.
1. Check the engine oil level, it should be empty.
2. See Table 3-5 and add the appropriate amount of oil to the engine crankcase.
3. Add a little at a time and check the oil level to ensure that you do not overfill the
crankcase. Stop adding oil when the oil level reaches the full line.
Coolant Level
AE25 only
1. Check the coolant level while the engine is cold, it should be full.
2. If the coolant level is low, add some coolant as recommended in the engine manual
(usually a 50/50 mixture of antifreeze and water).
