STANDBY POWER CONNECTIONS
The Ranger 9 is suitable for temporary, standby, or
emergency power using the engine manufacturer's rec-
ommended maintenance schedule.
The Ranger 9 can be permanently installed as a stand-
by power unit for 230V-3 wire, single phase 40 ampere
service.
WARNING
(Connections must be made by a licensed electri-
cian who can determine how the 115/230V power
can be adapted to the particular installation and
comply with all applicable electrical codes.) The
following information can be used as a guide by the
electrician for most applications (refer also to the
connection diagram shown )
IMPORTANT : When the Ranger 9 is connected to a
230 volt, 3-wire line, the unit should be operated with
the idler switch in the "HIGH" idle position to avoid load
sensing problems. If the machine is set for automatic
idle, the 230 volt circuit will sense loads and cause the
engine to accelerate to high idle. However, since only
one line of the circuit senses current, 115 volt power
drawn from only one line to neutral may result in the
engine not going to high idle.

RANGER 9
• Install a double pole, double throw switch between
the power company meter and the premises
disconnect.
Switch rating must be the same or greater than
the customer's premises disconnect and service
overcurrent protection.
• Take necessary steps to assure load is limited to
the capacity of the Ranger 9 by installing a 40 amp
230V double pole circuit breaker. Maximum
rated load for the 230V auxiliary is 40 amperes.
Loading above 40 amperes will reduce output
voltage below the allowable -10% of rated
voltage which may damage appliances or other
motor-driven equipment.
• Install a 50 amp 115/230V plug (NEMA type 14-50)
to the Double Pole Circuit Breaker using No. 8, 4
conductor cable of the desired length. See
Accessories Section for (The 50 amp 115/230V
plug kit.)
• Plug this cable into the 50 amp 115/230 V
receptacle on the Ranger 9 case front.
