7.0 INITIAL 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.
Hardwire Input Connections (For L14-30P Plug-in Connections, skip to 7.1 - L14-30P Plug-in Con-
nections—Including the PD-001 Distribution Box.)
1. Verify that the Input and Output circuit breakers are off.
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
in the sockets. Turn on the battery cabinet circuit breaker now.
5. If you are using a distribution box that includes a manual bypass switch, place the switch in
BYPASS position.
6. Turn on the branch circuit disconnect to apply voltage to the input terminal block.
7. Using a voltmeter, verify the expected L1-N, L2-N and L1-L2 voltages.
a. If no manual bypass switch is used, there will be no output voltage at this time. If a manual
bypass switch is used, verify that the same voltages appear at the Output terminals. If a
manual bypass switch is used, the Bypass lamp will light by the switch. If no manual bypass
switch is used, there will be no output voltage at this time.
b. If the configuration program has 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 at 127 VAC, then the input
phase angle is required to be 120 degrees (leading or lagging).
8. After verifying proper input voltage to the UPS terminal block, turn off the branch circuit power,
close all access panels to the distribution box and reapply input power.
9. Close the Input circuit breaker located on the distribution box. The green AC Input indicator
should illuminate on the front panel.
10. Press the On button for 1 second. The Bypass indicator will light for several seconds before the
UPS ON indicator turns on continuously. If the batteries are determined to charged above 80%,
an automatic battery test will run for about 15 seconds.
11. Close the Output circuit breaker on the rear of the UPS. If a manual bypass switch is used, the
UPS Available indicator by the switch will light. If a manual bypass switch is used, transfer the
switch to the UPS position. The output terminal block will be powered at this time.
12. Perform a Manual Battery Test - Press the On button for one (1) second. The front Battery
indicator will light for about 15 seconds and then return to only the UPS ON and AC Input
indicators being illuminated.
13. Review all setting option provided by the configuration program. Some changes require that the
UPS be OFF. If this is the case, these should be programmed before powering the loads. The
configuration program is described in the next section.
14. Connect all loads for normal operation.

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.
