GEH-6254 Installation Instructions
Connections
The screw terminals on the Voltage Conditioner
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 Voltage Conditioner 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 Voltage
Conditioner Assembly plug(s), align the receptacle
interlock connector of a Distribution Cable Harness with
the plug hook connector of the Voltage Conditioner
Assembly. Insert the receptacle until the interlock and
hook catch (see Figure 5).
To disconnect from the Voltage Conditioner Assembly,
press down at the rear of the receptacle interlock until
the interlock clears the plug hook and withdraw the
receptacle interlock (see Figure 6).

PARTS AND OPTIONS
There are no user-serviceable components or parts
within the Voltage Conditioner Assembly; however, in
order for the unit to be properly protected, the fuses
and fuse holders listed in Table 3 are recommended for
use with the Voltage Conditioner Assembly (connect to
the primary side of the three potential transformers).
Table 4 contains a list of potential transformers that
are recommended for use with the Voltage Conditioner
Assembly (all units rated 120Vac on the secondary
and are rated 1-VA @ 60Hz with 0.2% on magnitude
accuracy). These potential transformers must always
be protected. It is recommended that the primary side
of the potential transformer be fused with the fuses
previously described.
If it is preferred to purchase a voltage-sensing
accessory that has factory-mounted AC line fuses and
three 1-VA @ 60Hz accuracy potential transformers,
Table 5 contains a listing of GE Voltage Conditioner
Plates. These Voltage Conditioner Plates contain the
Voltage Conditioner Assembly as an integral part
of the plate and are factory-wired from the Voltage
Conditioner Assembly to the three 1-VA potential
transformers and to the fuses holders (one set of fuses
is included).
