2000 125A Ferroresonant Rectifier J85502C-1
Issue 8 July 1999
Installation 5 - 13
The J85502C-1 rectifier has a simple 208/240 Vac conversion
procedure. No internal wiring changes are required for the
conversion. A movable tab slides up or down when the two
mounting screws of TB1 are loosened approximately two or
three turns, not enough to dismount TB1.
When you loosen the mounting screws and slide the movable tab
down so that it covers the 208 marking, the tab blocks entry to
the 208 Vac hole on the ac input side of TB1. The lower drawing
in Figure 5-2 shows the tab in this position that is correct for 240
Vac input to the rectifier.
When you slide the movable tab to the position shown in the
upper drawing of Figure 5-2, it covers the 240 marking and
blocks entry to the 240 Vac hole on the ac input side of TB1.
Now the 208 marking shows, indicating that the rectifier is set
for 208 Vac input to the rectifier.
When the tab is set to the desired position, connect the ac lead to
the unblocked screws, 208 or 240. Put on the flat washer,
lockwasher, and nut. Torque to 25 in-lbs. The “green” ac ground
wire goes to the FR GRD/AC EG point. Retighten the TB1
mounting screws when finished and replace the clear plastic
shield.
Converting DC
Output Polarity
(Optional)
This section gives conversion procedures for the dc output
polarity of the Lineage
®
2000 J85502C-1 24-volt rectifier.
Polarity is determined by the electrical placement of the output
circuit breaker and may be changed in the field. The following
steps convert the rectifier from negative output (positive
ground) to positive output (negative ground).
In Figure 5-4, rectifier wiring appears as in the left drawing
before the work is started, and appears as in the right drawing
Note
The clear plastic shield in front of TB1 must be removed by
loosening the two mounting screws.
DANGER
This procedure MUST be performed ONLY on a rectifier that
is completely disconnected from the battery and plant bus
AND with ac power disconnected at the ac service panel.
