B.3 MPS-24A Main Power Supply
Connect the power run for the LDMs to MPS-24A TB3, Terminals 1 (+) and 2 (-). Maximum current is 1 amp. The power run to the
LDMs need not contain a Power Supervision Relay since loss of power is inherently supervised.
B.4 MPS-24B Main Power Supply
Connect the power run for the LDMs to MPS-24B, TB2, Terminals 1 (+) and 2 (-). No more than 200 mA current can be drawn from
these terminals in standby or alarm.
CAUTION: POWER-LIMITED WIRING
!
THE +24 VDC PROVIDED ON TB2 TERMINAL 3 IS POWER-LIMITED ONLY WHEN USED WITH THE MINUS RETURN
ON TB2 TERMINAL 4. DO NOT USE THE MINUS RETURN ON TB2 TERMINAL 2 WITH THE +24 VDC POWER ON TB2
TERMINAL 3.
