If 480 volt single phase load is to be run, the X lead must be one of the leads in the circuit in order for the automatic idle to function. Using a NEMA plug
All auxiliary power is protected by circuit breakers with the fol- lowing values:
Y
480 V
X | Z |
GND
(FOR ALL SINGLE AND THREE PHASE LOADS)
The 120V has 20 amp circuit breakers for each duplex recepta- cle. The 240V has 50 amp circuit breakers for each hot lead going the 240V receptacle.
The 480V 3 phase circuit breakers / switch has a 3 phase, 15 amp circuit breaker.
Ground Wire
Periodically check the ground wire at plugs, power cords and auxiliary loads to ensure that the grounding circuit is intact and connected.
MOTOR STARTING
Most 1.5 hp AC single phase motors can be started if there is no load on the motor or other load connected to the machine, since the full load current rating of a 1.5 hp motor is approxi- mately 20 amperes (10 amperes for 240 volt motors). The motor may be run at full load when plugged into only one side of the duplex receptacle. Larger motors through 2 hp can be run provided the receptacle rating as previously stated is not exceeded. This may necessitate 240V operation only.
The 480 volt 3 phase output of the RANGER 3 PHASE is capa- ble of running most 480VAC 3 phase motors up to 10HP. A 10HP motor must be started with no load on the motor and no other load connected to the machine, since the full load current of a 10HP 480VAC 3 phase motor is approximately 12.5 amps. Refer to the reconnect phase output to any load, the ground at the 3 phase receptacle is NOT the neutral of 3 phase connec- tion, and should under no circumstance be connected to the neutral of any 3 phase load.
