Initial Startup and Electrical Checks

7.0INITIAL STARTUP AND ELECTRICAL CHECKS

Initial Startup and the Configuration Program—The UPS ships with a default 120 VAC L-N setting. This is also the most robust setting in that it can operate with either input phase angle (120 or 180 degrees). Perform initial system checks first. If the UPS configuration needs to be modified for your application, then go to the next section to review use of the configuration program. Some config- uration changes require that the UPS be in the OFF mode while powered from the utility. Therefore, the installer must confirm that the UPS input has been properly wired. After re-configuring your UPS, the UPS may be put into service with the intended loads.

7.1Hardwire Input Connections

! WARNING

Miswiring power to the input terminal block (L1-L2-N-G) or connecting to single-phase voltages (L-N-G only) may damage the UPS.

1.Verify that the input and output circuit breakers are off. (To locate the circuit breakers, see Figure 1.)

2.During initial system checks, disconnect all loads (open load disconnects).

3.Inspect all wiring, cables and connection.

4.If external battery cabinets are used, verify that the battery interconnect cables are fully inserted into the sockets.

5.Turn on the battery cabinet circuit breaker.

6.Locate the UPS/Bypass circuit breaker on the rear of the UPS (see Figure 1).

7.Unscrew the thumbscrew and slide the bracket to the right (toward the Input Lamp) until it is past the arm of the breaker.

8.After the bracket has been moved to right, tighten the thumbscrew to secure the bracket in place.

9.Turn the UPS/Bypass circuit breaker to Bypass (On).

NOTE

When the UPS is operating in manual bypass mode of operation, indicators A, C, E, Fault and Bypass will be illuminated. These indicators, on the front panel, signify the UPS is operating in Manual Bypass mode. There will be audible alarm as well.

10.Turn on the branch circuit disconnect to apply voltage to the input terminal block (see 6.3.1 - Distribution Module Electrical Connections).

11.Using a voltmeter, verify the expected L1-N, L2-N and L1-L2 voltages.

a.The Input and Output lamps by the UPS/Bypass breaker will be illuminated.

b.If the configuration program as been used to set the L-N voltage at 100, 110, or 115, then the input phase angle is required to be 180 degrees.

c.If the configuration program as been used to set the L-N voltage to 127 VAC, then the input phase angle is required to be 120 degrees (leading or lagging).

12.After verifying proper input voltage to the UPS terminal block, turn off the branch circuit power and close all access panels to the distribution box.

13.Unscrew the thumbscrew and slide the bracket to the left (toward the Output Lamp) until it is past the arm of the breaker.

14.After the bracket has been moved to left, tighten the thumbscrew with your hand or use a slotted screwdriver to secure the bracket in place.

15.Turn the UPS/Bypass circuit breaker to the Inverter (OFF) position.

NOTE

When the UPS/Bypass circuit breaker is in the Inverter position, Indicators A, C, E, Fault and Bypass will not be illuminated and the audible alarm will clear.

16.Reapply input power.

17.Close the input circuit breaker located on the rear panel of the UPS. The green AC Input indicator should illuminate on the front panel.
