Auxiliary Power While Welding

A-8	INSTALLATION	A-8

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.

STANDbY POWER CONNECTIONS

The Ranger® 250 GXT is suitable for temporary, standby, or emergency power using the engine manu- facturer’s recommended maintenance schedule.

The Ranger® 250 GXT can be permanently installed as a standby power unit for 240V-3 wire, single phase 42 ampere service.

WARNING

(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® 250 GXT by installing

a50 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® 250 GXT case front.
