5. At the UPS, connect the ground wire to the ground (earth) terminal near the DC terminals as shown
in Figure 12. Connect the positive (+) cable to the + UPS DC terminal, and the negative (-) cable to
the - UPS DC terminal.
6. See Figure 12. At the battery cabinet, route the cables through the bottom of the conductor box.
Then, connect the ground wire to the ground (earth) terminal on the battery cabinet. Connect the
positive (+) cable to the + battery cabinet terminal, and the negative (-) cable to the - battery cabinet
DC terminal. Reattach the cover over the terminal strip.
306 Setting the Output Voltage DIP Switch
The DIP switch for setting the output voltage is on the back of the UPS, next to the communication port. The
chart below the switch shows the proper settings for each voltage. Make sure the UPS and its input breaker
are off, and if you have an optional bypass switch, make sure it is turned to “Bypass” or “Off.” Set the
DIP switches in the direction shown by the arrows for the inverter output voltage you need.
Figure 14
Note: When the UPS is in bypass
mode or the optional
maintenance bypass switch is
set to “Maintenance” or
“Bypass,” the DIP switches do
not control the output voltage.
