400 AMP DISCONNECT USER MANUAL 9

Power Up Sequence

Use the following procedure to power up unit:

Step 1. At house service main breaker, turn power ON.

Step 2. At rear of Disconnect, verify all phase indicators are lit (Figure 6).

Figure 6: Phase Indicators Location

Step 3. At front of Disconnect, check AC voltmeters. Voltages should read as follows:

Step 4. If meter readings are nominal, switch Main Breaker to the ON position (Figure 4).

Step 5. Verify that test point readings match LED meter readings for proper voltage.

Note

: Since the test points are

after

the Main Breaker, their voltages may be slightly lower than those indicated by the digital meters when

the Disconnect is under load. This is due to the internal resistance of the breaker causing a slight voltage

drop when current flows through it.

Note: The Pilot Light indicates when Main Breaker is energized (Figure 4). Press to test LED before Main Breaker is

"ON."
