ELECTRICAL HOOKUP

Once the generator is anchored in its final position, it is ready for electrical connections. The generator is supplied with two terminal blocks for connection of three distinct electrical circuits; main line output power, GFCI power input and remote start signal. Main line output power is the electrical output of the generator, GFCI input powers the battery charger and optional block heater devices and the remote start signal is the interface with an Automatic Transfer Switch that allows the generator to operate automatically upon a utility power outage.

DANGER

•Improper installation can damage your electrical system and cause property damage, serious personal injury or death. Installation MUST be performed by a licensed electrician and plumber, or gas technician and installation MUST comply with all applicable building and electrical codes. Some areas may require building permits and/or detailed sight inspections prior to approving the unit for operation.

To access the wiring connection terminal blocks, open the generator lid (A) and place the lid prop rod (B) into the slot (C) on the underside of the lid. Remove the three screws (D) from the access panel, then open the hinged access panel (E) as shown in Fig A. The access panel is removable by pulling the pins from the panel hinges. Locate the two terminal blocks (F) on the lower right corner of the engine partition panel.

MAIN LINE OUTPUT POWER

The output circuit of the generator is 4-wire, 240V, rated for the amperage as shown on the generator nameplate. Connection to the transfer switch requires two leads, commonly referred to as "hot" leads (L1 & L2), a neutral (N), and ground lead. Positions of these leads are labeled on the main line output terminal block, also shown in Fig. B. Select proper power output wire sizes according to allowable ampacities given in Table 310-16 of the latest revision of The National Electric Code(NFPA 70). To connect the wires, strip the insulation back approximately ½" from the end of the wire, insert the stripped end into the terminal block, then torque the terminal block screw to 35 in-lbs (4.0 N-m).

DANGER

•Hazardous voltage can cause severe injury or death. Electrocution is possible whenever electricity is present. Open the main circuit breaker of all power sources before servicing the equipment. Configure the installation to electrically ground the generator set, transfer switch and related equipment and electrical circuits to comply with applicable codes and standards. Never contact electrical leads or appliances when standing in water or on wet ground because these conditions increase the risk of electrocution.
