The Optional Power Supply (OPS) is required when either a Remote Alarm Status Panel or the Multiple Circuit
Breaker Option is to be installed.
The OPS option must be installed in Location 5. (See Figure 3 for option locations.)
!
CAUTION
To install the Optional Power Supply the UPS will need to be in Maintenance
Bypass and the battery circuit breaker(s) will need to be turned off. The Control
Power and Fan fuses must be opened.
8.1 Installation
Install the OPS option in the Npower UPS per the instructions in Section 4 and in this section. Once installed,
the OPS option needs to be connected to the CANbus. If it is the first option installed, utilize the system CANbus
cable that is coiled in the center of the option area. If another option has been previously installed and connected
to the system CANbus cable, disconnect the CANbus cable from the previously installed option at terminal P999
and reconnect the CANbus cable into terminal P999 of the Option Power Supply as shown in Figure 37 and Figure
38. Connect the jumper cable from OPS terminal P966 to the previously installed option terminal P999.
Connect one end of harness 77-814000-04, supplied in this kit, to TB2 behind the lower front UPS panel as
shown in Figure 37 and Figure 38, Detail B. Connect the other end to the bottom left side of the Option Power
Supply as shown in Figure 39
See OPS Installation Notes at the end of this section.
