NOTE
Locations where power plant may be
exposed to high humidity, sand, or dust,
should be avoided whenever possible.
Moisture condenses on power plant parts
and may cause corrosion. Sand, dust,
and dirt shorten life of parts and can
cause mechanical failure.
(2)
Position
the
power
plant
on
any
reasonably level surface, then adjust position to obtain
as near level as possible.
NOTE
Do not operate power unit if front to rear
axis is more than 15 degrees from level
with up to 10 degrees displacement to
either side.

Installation Connections.
(1)
Grounding Procedure. The power unit
shall be grounded in order to prevent shock due to
defective insulation, or external electrical faults. Poor
grounding can endanger personnel, may damage
equipment,
and
can
create
interference
in
communication or electronic circuits. Install one of the
following items as a grounding device:
(a)
Drive a ground rod (fig. 1-15, sheet
7 of 7) to a depth of at least 8 feet. This is the preferred
device which is shipped with the power unit. (An
existing underground pipe may be used in an
emergency.)
(b)
Bury a 1/4 inch thick iron or steel
plate or 1/16 inch thick aluminum or copper plate, 18
inch x 18 inch in size, with a ground cable attached, to
depth of at least 4 feet.
(c)
Position a 1/4 inch thick iron or steel
plate, or 1/16 inch thick aluminum or copper plate,
approximately 18 inch x 18 inch size, on the hard
ground or bedrock beneath the trailer stand or roll the
wheel of a trailer or truck until it comes to rest on top of
the grounding plate.
