FIELD POWER SUPPLY 208/230/460/575-3-60. MINIMUM CIRCUIT AMPACITY AND
MAXIMUM SIZE AND TYPE OF BRANCH-CIRCUIT SHORT-CIRCUIT AND GROUND-FAULT
PROTECTION PER UNIT RATING PLATE. PROVIDE DISCONNECTING MEANS AS REQUIRED.
TYPICAL MOTORS AND COMPRESSORS SHOWN. SEE CONNECTION DIAGRAM ON MOTOR
OR COMPRESSOR FOR ACTUAL WIRING DETAIL.
IF POWER MONITOR OUTPUT CONTACTS DO NOT TRANSFER WHEN POWER IS APPLIED TO
UNIT (LED GLOWS RED DURING FAULT CONDITIONS):
1. VERIFY THAT ALL THREE PHASES ARE PRESENT AND ARE OF THE CORRECT VOLTAGE. IF
ALL THREE PHASES ARE PRESENT AND ARE OF THE CORRECT VOLTAGE, PHASE ROTATION
MAY BE INCORRECT. PERFORM STEP 2.
2. DISCONNECT POWER TO THE UNIT. VERIFY THAT POWER IS IN FACT DISCONNECTED.
SWAP ANY TWO OF THE THREE UNIT POWER SUPPLY WIRES. WHEN POWER IS REAPPLIED,
OUTPUT CONTACTS SHOULD NOW TRANSFER.
