Installing UPS ground cabling
Use the manufacturer’s documents to install and cable a UPS. If the UPS does
not contain an integral bypass switch, add one externally during initial UPS
wiring. Figure 31 is a block diagram of a UPS installation and associated
wiring.
Follow Procedure 5 to install UPS ground cabling.
Note: Because UPS installation can be complex, Nortel recommends
that installers attend vendor training programs.
