CONNECTING THE LOADS
WARNING:
All wiring must be done in accordance with National
Electric Code NFPA 70.
There are three ways the loads may be connected to the
1. Receptacle Panel -
A variety of receptacles have been provided for your
convenience . The 120V receptacles are powered when
the voltage selector switch is in the 120/240 single phase,
and 120/208V three phase position. The 240V
receptacles are only usable in the 120/240V single phase
In the 120/208V position, the 240V receptacles have
only 208V at them. Refer to the voltage output table,
located previously in this manual.
2. Full Power Load Connection Terminal Block -
For remote connections and connecting load distribution
boxes, heavy duty terminal blocks have been provided.
These terminal blocks are located on the rear of the unit
The neutral and ground are connected together
at this panel. For use with an isolates neutral, remove the
jumper strap between the neutral connection block and
the ground lug. This will isolate the neutral from the
ground and allow your a single point grounding at a
distribution panel. When using these terminal blocks,
be sure to use wire rated large enough to carry your full
load or the full rated load of the generator.
3. Full Power Cam-Lock Connections -
For ease of connecting and disconnecting loads, these
units have been equipped with Cam-Locks located
behind the right hand, rear door. See the Cam-Lock
Connections in this manual. Instructions for the Full
Power load Connection Terminal Block apply for the
Cam-Locks. If you need to run an isolated neutral system,
the jumper between the neutral and ground musts be
removed at the terminal block.
