INSTALLATION
RANGER GXT
A-8
STANDBY POWER CONNECTIONS
The RANGER GXT is suitable for temporary, standby,
or emergency power using the engine manufacturer
’ s
recommended maintenance schedule.
The RANGER GXT can be permanently installed as a
standby power unit for 240V-3 wire, single phase 42
ampere service.
(Connections must be made by a licensed electri-
cian who can determine how the 120/240V 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 in Figure 1.)
-------------------------------------------------------------------------
1. 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.
2. Take necessary steps to assure load is limited to
the capacity of the RANGER GXT by installing a
50 amp 240V double pole circuit breaker.
Maximum rated load for the 240V auxiliary is 42
amperes. Loading above 42 amperes will reduce
output voltage below the allowable -10% of rated
voltage which may damage appliances or other
motor-driven equipment.
3. Install a 50 amp 120/240V plug (NEMA type 14-50)
to the Double Pole Circuit Breaker using No. 8,
4 conductor cable of the desired length. (The
50 amp 120/240V plug is available in the
optional plug kit.)
4. Plug this cable into the 50 amp 120/240V
receptacle on the RANGER GXT case front.
WARNING
AUXILIARY POWER WHILE WELDING
Simultaneous welding and power loads are permitted
by following Table I. The permissible currents shown
assume that current is being drawn from either the
120V or 240V supply (not both at the same time).
Also, the
“ Output Control ” is set at “ 10 ” for maximum
auxiliary power.
