14. If removed, reinstall the safety shield panel removed in paragraph 5.1, Step 5. Secure with the retained
hardware.
15. If removed, reinstall the left front panel removed in paragraph 5.1, Step 4 and secure with the retained
hardware.
NOTE When installing external wiring to the Powerware Hot Sync CAN Bridge Card,
conduit must be installed to the UPS cabinet. When installing internal wiring to the
Powerware Hot Sync CAN Bridge Card terminals, route the wiring through the
internal opening in the X-Slot communication bay.
NOTE When installing interface wiring for the pull chain, conduit must be installed
between UPSs.
NOTE Setup of the Powerware Hot Sync CAN Bridge Card for parallel operation must be
performed by an authorized Eaton Customer Service Engineer. Contact an Eaton
service representative to schedule a date.
