In Figure 5 an Option Power Supply (OPS) and a Remote Status Panel (RAS) have been added to the CANbus.
The Option Power Supply contains an isolated CANbus repeater so the CANbus in the OPS/RAS loop is considered
to have originated at that point only to the RAS panel. The isolated output of the OPS is pre-configured with
a terminator on the included terminal block.
Notes For Figure 5
1. CANbus cable for providing power and signals for the communication option is installed in the UPS and is
coiled up in the option section.
2. Connect the CANbus cable to P999 of the option located in Location 4. See Section 8 if option D, Option
Power Supply is to be installed.
3. Always insure that the CANbus cable originating from the power supply PWA gets connected to P999 of the
bottom-most option of the group in Locations 1 through 5. (Option in Location 6 is not considered as part of
this group.)
4. Additional options can be cabled together using one of the CANbus jumper cables. The jumpers plug into
connector P966 of the lower option and into connector P999 of the next option above.
5. All user option connecting cables are to be provided by others and are to be 16 gauge 300V Min. tinned
copper stranded wire. All option connections are made in the option section. Customer wires route through
option plate.
6. Option connection cables must be run in separate conduit from CANbus power cables.
7. Use short CANbus jumper (PN 77-814000-04) to daisy chain options.
8. Use long CANbus jumper (PN 77-814000-03) to connect P966 at Location 3 and 4.
