C. The foundation surface should be flat.
D. Space is required around the generator for mounting
switching devices, making connections, and for servicing.
E. The generator mounting backet must rest evenly and firmly
on the foundation. Install shims if necessary to even out
the foundation under the mounting pads then bolt the gen-
erator firmly in place.
TRAILER MOUNTING
Mount the generator on a trailer if you plan to use it as a
portable power source. See Figure 4. When selecting or
building a trailer to mount the generator, consider the follow-
ing points:
A. The trailer construction must be strong enough to support
the generator.
B. The design of the trailer must enable the trailer to remain
stable during operation, and to resist tipping caused by
generator starting and reflected load torque.
WARNING: Personal Injury & Equipment Damage
TRAILER MAY TIP OVER AND CAUSE INJURIES IF
WHEELS ARE NOT SPACED FAR ENOUGH APART.
C. The trailer height and mounting position of the generator
on the trailer should enable aligning the drive shaft (tum-
bling bar) in a straight or nearly straight line between the
power take-off and generator input shafts. Misalignment
must be less than 15 degrees during generator operation,
even though the mechanical design of the tumbling bar
would allow greater misalignment.
D. The generator mounting area of the trailer bed should be
flat.
E. The generator mounting bracket must rest evenly and
firmly on the trailer bed. Install shims if necessary to even
out the bed under the mounting pads, then bolt the genera-
tor firmly in place.
5. Insert the brass pin (with cable) into the plug body, and
line up the retainer pin holes in the brass pin with those
in the plug body.
6. Insert the retainer pin, and tap it firmly into place. The
retainer pin will protrude approximately 3/8" when fully
seated. (See Figure 1.)
7. Repeat steps 4 through 6 for each brass pin. Make sure
to connect the neutral lead (cable), identified and color
coded in conformance with the applicable local electrical
codes, to the large diameter pin (“N”) on the plug.
WARNING: Electrical Shock
DURING THE NEXT STEP, THE LOAD DISCONNECT PLUG
SHOULD NOT BE PLUGGED INTO ITS RECEPTACLE.
ALSO, MAKE SURE THAT THE EQUIPMENT TO WHICH
THE PLUG LEADS (CABLES) ARE BEING CONNECTED IS
NOT ENERGIZED (LIVE).
8.
Strip the insulation off the free end of each of the plug
leads (cables), and connect them to the load transfer switch
(or directly to the load).

The only assembly work required after unpacking the
generator is to assemble and wire the load disconnect plug,
which is contained in the subpack carton packed in the
generator crate. This load disconnect plug is a Alpha type 4
wire locking plug. The instruction for wiring the plug are in
the box with the plug. The gauge wire required will depend
on the type of wire you buy. You will need wire of sufficient
size to carry 50 amps at 240 volt. Consult with your local
wire supplier for the proper gauge and type.
Installation
FOUNDATION MOUNTING
Mount the generator on a foundation if it is to be used as a
permanent or standby power source (see Figure 2). See
“TRAILER MOUNTING” if generator will be used as a
portable power source (see Figure 3). When planning a
foundation consider the following points:
A. The foundation location should enable aligning the drive
shaft (tumbling bar) in a straight or nearly straight line be-
tween the power take-off and the generator input shaft.
Misalignment must be less than 15 degrees during gen-
erator operation, even though the mechanical design of
the tumbling bar would allow greater misalignment.
B. The foundation must be solid enough to absorb genera-
tor starting and reflected load torque during operation.
