Connecting a 582140000 Main Power Bay to a

582121100 Power Bay and/or 582121900/582121901

Distribution Bay (MCA and LMS Interconnections)

See Figure 4-27.

Interface Notes

1) Program and connect the two systems for the Power Share feature in the 582140000

System.

2) Lockout local access to the MCA located in the 582121100 Power Bay or

582121900/582121901 Distribution Bay.

3) Ensure remote access to the MCA located in the 582121100 Power Bay or

582121900/582121901 Distribution Bay is enabled.

4) Install the RS-485 option (if not already furnished) onto the MCA located in the

582121100 Power Bay or 582121900/582121901 Distribution Bay.

If RS-485 option is already installed on the MCA located in the 582121100 Power

Bay or 582121900/582121901 Distribution Bay, disconnect the cable.

5) Connect the LMS in the 582140000 System to the MCA in the 582121100 Power Bay

or 582121900/582121901 Distribution Bay (connect cable from the LMS RS-485

connector in the 582140000 System to the RS-485 connector on the MCA Panel in

the 582121100 Power Bay or 582121900/582121901 Distribution Bay).

6) If an LMS1000 is installed in the 5821900/582121901 Distribution Bay and contains

I/O cards, replace the Main LMS CPU card with an Expansion LMS CPU Card (P/N

506153), and connect the LMS1000 to the LMS network in the 582140000 System.

7) If a DGU is installed in 582121900/582121901 Distribution Bay, then...

a) Have LMS Gateway Port Software Option installed.

b) Connect a cable from the DGU local port to the connector located on the front of

the LMS CPU card installed in the 582140000 Main Power Bay. This cable is a

straight through cable with a DB-9 (female) end and a DB-9 (male) end. This

cable connects between the DGU COM1 card, Port A, and the LMS

RS-232 port

located on the front of the LMS card assembly.

Note: DGU communication is a telnet gateway through the LMS to the DGU. It

IS NOT communication between the DGU and the LMS. Alarms in the DGU

cannot be recognized by the LMS unless they are individually hard wired.
