3-1-7 Startup - Power-Reg, Ultra-Reg and Phase Stabilizer (100 - 400 kVA)
After connecting the input and output cables and before placing the unit in service, verify the output voltage
using the following procedure.
Tools Required
• Phase Rotation Meter
• Voltage
meter
DANGER!!
FATAL ELECTRIC SHOCK HAZARD!! TO PREVENT FATAL ELECTRIC
SHOCK DISCONNECT POWER FROM UNIT AND LOCK OFF BEFORE YOU
PERFORM THE FOLLOWING PROCEDURE.
PROCEDURE:
1. Verify that facility circuit breaker is OFF, locked and tagged according to OSHA requirements.
2. Check power connections.
3. Verify that there are no obstructions that restrict air flow.
4. Unlock facility circuit breaker and set to ON.
5. Check that input power is phased in clockwise rotation (A, B, C). Use phase rotation meter. And check two
hot wires for single phase Power-Reg.
6. Measure the input voltages phase to phase and be sure the readings agree with the values listed on the
label plate.
7. Measure the line-to-neutral output voltages as follows:
a. Verify that output line to neutral voltages agree with the values listed on the label plate located on the
front panel and in Appendix A.
• If output voltage readings are out of specification, refer to Section 3-1-9, Calibrate Control Logic
Board, otherwise, continue to next step.
8. Turn OFF power to connected load.
9. Turn OFF facility circuit breaker, lock and tagout according to OSHA requirements.
