2000 25A Ferroresonant Rectifier J85502A-1
Issue 4 May 1998
Installation 5 - 9
4. If the controller is an MCS, cut leads TP0 and TP2 (pin
numbers 21 and 19) in the controller end of the cable (see
your controller manual). This signals to an MCS that the
rectifier is a 25A.
5. The next action depends on the type of plant:
• For connection to a Galaxy controller, remove the
plastic cover on the back of the bay housing the
controller. The back of the controller has positions for
up to three RIMs (Rectifier Interface Modules) in
positions A (G1 to G8), B (G9 to G16), and C (G17 to
G24). The RIM required for use with the J85502A-1
rectifier will be the MCS-compatible style, with eight
positions of 24-pin jacks and a metal retaining clip.
• For Microprocessor Controlled System (MCS) plants or
Conventional Controlled System (CCS) plants, remove
the plastic cover on the back of the bay housing the
controller. The back of the controller has sixteen 24-pin
connectors labeled Rect 1 through Rect 16.
• For Expandable Controlled System (XCS) plants, open
the front panel and thread the control cable through the
hole in the wall of the controller. There are six 16-pin
connectors labeled Rect 1 through Rect 6.
• For Evolutionary Control System (ECS) plants, open the
front panel and thread the control cable through the slot
inside the controller. On the backplane of the lower
panel on the controller there are six 40-pin connectors
labeled Rect 1 through Rect 6.
6. Plug the cable into the connector assigned to the rectifier
number determined in Step 3 above. This action will cause
a minor alarm in an MCS controller. For a Galaxy
controller, the rectifier position used must be programmed
according to instructions found in the Galaxy controller
product manual.
Warning
Remove the REG fuse associated with the rectifier from the
controller.
