3.3.1 Bezel Connection
Plug the 24 VAC power plug from the transformer
into its 3-pin terminal on the back of the Power
Center PCB (see Figure 7). Mount the Bezel to the
Power Center using the screws provided. Ensure
that battery wires are kept from being pinched or
damaged.
CAUTION
DO NOT INSTALL BATTERY until ready to
power up system.
3.3.2 PDAJ-BoxCableConnectiontoPower
Center PCB
Make provision for the cable to be run between the
PDA J-box and the Power Center. Never run high
voltage and low voltage in the same conduit. Pull
cable through the knockout with the Heyco fitting
and into the low voltage compartment. Strip back
jacket 6". Strip each wire a ¼" and connect to the
red, 4-pin connector on the Power Center PCB. A
multiplex kit may be required if there are more than
two cables running to a red, 4-pin connector (see
Figure 8).
NOTE For detailed tranceiver installation, see
Section 3.7.1.
