Step Action
1. Verify the power source is unfused.
2. As instructed in the fol-
lowing paragraph, con-
nect office battery and
return (20Vdc to 60Vdc)
to the screw-down wire-
binding connectors la-
belled “A” at either top-
rear corners of the chas-
sis. For example, for a
-48V dc plant, connect -48V to -A and RTN to +A; for a +24V
plant, connect +24V to +A and RTN to -A.
Loosen the set screws for each, insert the wires, and tighten the
screws.
3. To ensure power redundancy, repeat Step 2 for Side B using a sepa-
rate power source. If you are not using a second source, connect
Side B to the same source as Side A to avoid triggering an alarm.
4. If a mating connector is used, insert the connector into the recepta-
cle and tighten the two screws until the connector is securely in
place.
5. Fuse the power source to supply power to the chassis.
