GEH-6251 Installation Instructions
Connections
The screw terminals on the Power Supply Plate are
labeled by function for clarity. The terminal strip
pockets on the AC INPUT fuse block will accommodate
a spade lug or ring terminal with a tongue width up
to 0.45 inches. The terminal screw size is 10-32. The
terminal strip pockets on the Power Supply Assembly
will accommodate a spade lug or ring terminal with
a tongue width up to 0.320 inches. The terminal
screw size is 10-32. To make the connection, attach
an appropriate spade lug or ring terminal to the wire,
then slip the fastener beneath the terminal screw and
tighten. The Power Supply Plate also contains two
12-pin plug connectors. The connectors are keyed
so they cannot be inserted incorrectly into a mating
12-pin receptacle connector. To connect to the Power
Supply Plate plug(s), align the receptacle interlock
connector of a Distribution Cable Harness with the
plug hook connector of the Power. Supply Plate. Insert
the receptacle until the interlock and hook catch (see
Figure 6). To disconnect from the Power Supply Plate,
press down at the rear of the receptacle interlock until
the interlock clears the plug hook and withdraw the
receptacle interlock (see Figure 7).

Parts And Options
The only user-serviceable components or parts 011
the Power Supply Plate are the fuses in the AC INPUT
fuse block. The fuses listed in Table 4 are recommended
as replacements for use with the Power Supply Plate.
Failure to use the proper type of fuses can result in
damage to the Power Supply Plate. Two fuses per
Power Supply Plate are required. If you prefer to
purchase a +24Vdc Power Supply without the factory
mounted AC line fuses or a control power transformer, a
Power Supply Assembly is available. This Power Supply
Assembly always requires AC line fuse protection and
in applications where the AC input voltage is greater
than 240Vac @ 60 Hz, a control power transformer
will always be required to step the voltage down to
85-240Vac @ 60 Hz. Table 5 lists the details on the GE
Power Supply Assembly.
