Installing a PFTU
Use the following procedure and any instructions provided with the Power
Failure Transfer Unit (PFTU) to install and connect PFTUs.
Procedure 13
Installing a PFTU
1 Install a PFTU according to the manufacturer’s instructions.
2 Attach the yellow PFTU label to the designation strip, indicating the top
connector as P1 and the bottom connector as P2.
3 Install two NE-A25B type 25-pair cables from connectors P1 and P2 on
the front of the PFTU to the PFTU termination area at the MDF.
4 Cross-connect wiring for PFTU operation as shown in Table 6.
5 For AC-powered systems, install the A0367916 auxiliary power supply.
a. Attach the unit to the wall using screws in the four mounting holes.
b. Connect a #24 (or larger) AWG wire from the –48 V connection on
the auxiliary power supply to the PFTU termination area on the MDF.
