circuit card (separately ordered – See List 71). The MCA then provides alarm display messages
and an audible alarm when a surge suppression assembly activates. Order a List 71 MCA I/O
Circuit Card as required to provide MCA binary inputs for the surge suppression alarms.
3) Note that two (2) MCA customer alarm relay circuit cards are provided with the primary bay. If remote
surge suppression alarm relay contacts are required and you expect to use the alarm relays on the
factory provided cards for other uses, order a List 70 MCA relay circuit card as required.
List 38: Surge Suppression for 480VAC Input
Features
♦ Provides two (2) surge suppression assemblies for the Power Only Bay. One wired to Rectifier AC input
circuit breakers CB1, CB3, CB5, CB7, and CB9. The other to CB2, CB4, CB6, CB8, and CB10.
♦ 100kA interrupting capacity.
♦ Overcurrent fusing and thermal protection.
Restrictions
For use with List 4 and 14.
See Surge Protection in the SPECIFICATION section for additional ratings.
Ordering Notes
1) Order if additional surge suppression is required.
2) A wire harness is factory connected to Form-C relay contacts located on each surge suppression
assembly for remote monitoring. Connect the wire harness to the first two binary inputs on an MCA I/O
circuit card (separately ordered – See List 71). The MCA then provides alarm display messages and an
audible alarm when a surge suppression assembly activates. Order a List 71 MCA I/O Circuit Card as
required to provide MCA binary inputs for the surge suppression alarms.
3) Note that two (2) MCA customer alarm relay circuit cards are provided with the primary bay. If remote
surge suppression alarm relay contacts are required and you expect to use the alarm relays on the
factory provided cards for other uses, order a List 70 MCA relay circuit card as required.
List 50: Optional LMS Main CPU Circuit Card (Primary Power/Distribution and Power Only Bays)
Features
♦ Provides the LMS Monitoring System.
♦ Refer to SAG586505000 for further information.
Restrictions
The LMS Monitoring System Main CPU circuit card is mounted in the Primary Power/Distribution and Power
Only Bays.
Ordering Notes
1) Order the optional LMS Monitor if increased monitoring capabilities are required. Order the LMS Main
CPU circuit card (List 50) for the Primary Power/Distribution and Power Only Bays. Order the LMS
Expansion CPU circuit card (List 63) for Secondary Power/Distribution and Power Only Bays that are to
be equipped with LMS I/O circuit cards.
2) Order additional LMS Network cables as required per Replacement/Additional LMS Network Cables.
Note that LMS Network cables are factory provided with Lists 11, 12, 13, 14, and 15.
3) This List option only provides the LMS CPU circuit card for the Primary Power/Distribution and Power
Only Bays, additional LMS options must be ordered separately per SAG586505000.
List 63: Optional LMS Expansion CPU Circuit Card (Secondary Power/Distribution and Power Only Bays)
Features
♦ Allows LMS I/O cards to be installed in Secondary Power/Distribution and Power Only Bays.
