2000 400A, 60Hz Ferroresonant Rectifier J85503C-3

Installation 5 - 15
backplane of the lower shelf inside the controller, the ECS-6U has
six 40-pin connectors labeled Rect 1 through Rect 6. The
ECS-12U has twelve 40-pin connectors labeled Rect 1 through
Rect 12.
Warning: Remove the REG fuse associated with the rectifier from
the controller.
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. Therefore, notify alarm personnel that the
unit is being installed.
7. If the rectifier is connected to a Lucent Technologies controller,
verify that the rectifier S2.1 switch on the 330C interface board,
CM4, is in the disable position. An MCS controller must have
version 4 software to enable an equalize feature. If the MCS has
version 4 software, cut strap ST1 on circuit module CP2 in the
controller. This allows the equalize feature to operate correctly
without causing the rectifier to shut down. The ECS-6U controller
automatically enables equalize, and the CCS controller does not
have a provision for equalize.
8. Dress and tie down the cable to provide stress relief at the
connector.
9. If rectifiers are to be operated in load share and are being used
with other than a Galaxy controller with the associated “enhanced
signals” control cable, connect a 20 gauge wire from TB3-7 on
CM4 to TB3-8 on CM4 of the adjacent rectifier. See Figure 5-6.
The wire must be UL recognized with minimum ratings of 80° C
and 150 volts ac. All load-sharing rectifiers must be “daisy-chain”
connected in this manner.
In addition to the signals provided when a Lucent Technologies
controller is used, 34 signals are readily accessible on the CM4
interface board via terminal strips TB1, TB2, and TB3. Note that
when a Lucent Technologies controller is used, no connections are
permitted from an external alarm/control bay to R+, R-, BAT and
GND located on TB1 and TB2. When a Lucent Technologies
controller and an external monitoring system are used with the
rectifier, the user provides the control cable assembly which links
the rectifier to the external monitoring system. All 34 signals
obtained from TB1, TB2, and TB3 are also present in a Lucent
Technologies controller, except the following:
