Power Failure Transfer Unit Wiring
The Power Failure Transfer Unit (PFTU) is wired from the 25-pair connector to the MDF, cross
connected to the CO Line inputs from the telephone company, to the CO Line inputs of the
system, and to Power Failure SLTs. The basic connections are shown in
Figure 3-40 and the
connector configuration is given in Table 3-19 . Note that the SLT may also be connected to a
SLIB as shown in the figure.

Wall Mounting the Electronic Key Telephone
All connections to the Electronic Key Telephone are fully modular. To wall mount the
Electronic Key Telephone, it is necessary to have one Wall Mount Kit and one standard-type
jack assembly designed for normal wall hanging applications.
1. Unplug the line cord from the phone. This line cord is not be required and should be
retained as a maintenance replacement item.
2. Lift the plastic number retainer upward and expose the screw underneath. Remove the
screw and the handset tab. Replace it with the handset tab from the Wall Mount Kit.
3. Be careful to position the tab so that the protrusion faces the hookswitch. This allows the
handset to remain secure when the telephone is on the wall. Replace the screw and snap
the number retainer into place.
4. Substitute the short modular cord from the Wall Mount Assembly into the modular
connector vacated by the line cord.
5. Align the wall mount baseplate with holes on the bottom of the telephone. Snap in place.
6. Now match the two key hole slots on the baseplate with the lugs on the 630-A type jack.
Align the modular connector and slide telephone into place. Refer to Figure 3-41 .
