Converter Input Cabling (+GND Connection)
Terminate the #6 AWG cable with pre-terminated 1/4”-5/8”C lug (with wire marker #13) to the
+GND input terminal labeled “E2” using hardware supplied with shelf.
Route the un-terminated wire end up behind the CXPS system over the top of the distribution
center.
Cut wire to size, strip cable sheath, and crimp supplied 1/4”-5/8”C lug.
Attach lug to distribution tier return bar. Use the hardware supplied with the CXPS system for
attaching lug.
Converter Input Cabling (-48V Connection)
Terminate the #6 AWG cable with pre-terminated 1/4”-5/8”C lug (with wire marker #14) to the
-48V (hot) input terminal labeled “E1” using hardware supplied with shelf.
Route the un-terminated wire end up behind the CXPS system over the top of the distribution
center.
Cut wire to size, strip cable sheath, and crimp supplied 1/4”-5/8”C lug.
Attach lug to breaker output terminal. Use the hardware supplied with the CXPS system for
attaching lug (reference Figure 12 for breaker locations).

Attach other unterminated wire end to TB11-36 “Conv Fail” on internal alarm board with Vista II
UDC (reference Figure 13 for alarm board details as well as -08 connection drawing at rear of
this manual).
5.5.2.3 Final Steps
Reattach back cover to converter shelf.
Install breakers as needed in 10-position breaker tier for required 24V distribution.
Cable from 24V loads to distribution as required.
Plug in 50A 48V feeder breaker into distribution tier.
Switch 50A feeder breaker to “ON” position to supply power to converter shelf.
Refer to Cordex Controller Software manual for custom alarming options using the two new
digital alarms (+24V distribution and converter fail).
