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 3-4. Use the appropriate size wire as required by NEC and local codes.
1. Open the enclosure electrical access panel door.
2. Connect the ground wire to the “earth ground connection” terminal shown in Figure 3-4.
This is the local ground reference to ground the generator enclosure and frame.
Battery Connections The generator is shipped with no battery installed.
Caution: This generator must have a battery installed for operation. The battery is used during starting
and during operation. If engine operation is attempted while the battery is removed, damage
to the engine’s electrical components may result.
WARNING: Installation and servicing of batteries is to be performed or supervised by personnel
knowledgeable of batteries and the required precautions. Keep unauthorized personnel away
from batteries.
WARNING: Do not dispose of battery or batteries in a fire. The battery is capable of exploding. If the
battery explodes, electrolyte solution will be released in all directions. Battery electrolyte
solution is caustic and can cause severe burns and blindness. If electrolyte contacts skin or
eyes, immediately flush the area with water and seek medical attention quickly.
WARNING: Do not mutilate the battery . The battery contains electrolyte solution which is caustic and
can cause severe burns and blindness. If electrolyte contacts skin or eyes, immediately flush
the area with water and seek medical attention quickly.
WARNING: A battery presents a risk of electrical shock hazard and high short circuit current. The
following precautions are to be followed when working on batteries:
1. Remove watches, rings, necklaces and all other metal objects.
2. Use tools with insulated handles.
3. Wear safety goggles, rubber gloves and boots.
WARNING: The battery electrolyte is a dilute sulfuric acid that is harmful to the skin and eyes. It is
electrically conductive and corrosive. The following precautions are to be followed when
working on batteries:
1. Wear full eye protection (safety glasses or goggles) and protective clothing.
2. Where electrolyte contacts the skin, flush the area immediately with water and wash it
off using soap and water.
3. Where electrolyte contacts the eyes, immediately flush the eye thoroughly with water
and seek medical attention quickly.
4. Spilled electrolyte is to be washed down with an acid neutralizing agent. A common
practice is to use a solution of one pound (500 grams) bicarbonate of soda to one
gallon (four liters) of water. the bicarbonate solution is to be added until evidence of
reaction (foaming) has ceased. The resulting liquid is to be flushed with water and the
area dried.
