Battery Charger Considerations
1.Mount the battery charger on the generator or as close to the generator as possible.
2.If you mount the battery charger inside the building, mount it near the main breaker box or disconnect box.
3.If you mount the battery charger outside, you must protect it from the environment and the elements.
4.Do not mount the battery charger where flammable liquids or vapors are present.
General Wiring Considerations
1.When routing the interface wiring, do not route it up against anything that could cut or chafe the wiring. do not route the wire up against any hot or potentially hot object.
2.Make sure that all the electrical components (generator set, transfer switch, battery charger, etc.) share a common hard wired ground.
3.Check with your local building inspector to determine what you must do to comply with the local regulations for grounding of this type of permanent installation.
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
Warning: Do not connect the generator output neutral to the frame or local ground. The generator output is isolated from ground. NEC and local codes require that the generator output remain isolated from local ground reference.
