GEH-6253 Installation Instructions
Connections
The screw terminals on the Power Supply Assembly
are labeled by function for clarity. The terminal strip
pocket 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 Assembly 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 Assembly plugs, align
the receptacle interlock connector of a Distribution
Cable Harness with the plug hook connector of the
Power Supply Assembly. Insert the receptacle until the
interlock and hook catch (see Figure 6). To disconnect
from the Power Supply Assembly, 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
There are no user-serviceable components or parts
within the Power Supply Assembly; however, in order
for the unit to be properly protected the 85Vac to
240Vac 60Hz INPUT must be fused. Table 3 lists the
fuses and fuse holders that are recommended for use
with the Power Supply Assembly.

Power Supply Assembly.

If the incoming AC power supply is greater than the
240 Vac @ 60 Hz maximum rating of the Power Supply
Assembly, then refer to Table 4 for a listing of GE control
power transformers that are recommended for use
with the Power Supply Assembly. The INPUT to the
Power Supply Assembly must always be protected. It
is recommended that the primary side of the control
power transformer be fused with the fuses previously
described.
If there is a preference to purchase a +24Vdc Power
Supply that has factory-mounted AC line fuses and/
or a higher AC voltage rating, Table 5 contains a listing
of GE Power Supply Plates. These Power Supply Plates
contain the Power Supply Assembly as an integral
part of the plate and are factory-wired from the Power
Supply Assembly to the control power transformer
(where required) and to the fuse holders (one set of
fuses is included).
