1.1 DC Power Supply
The MXP554 requires a 24V power supply.
Connect the 24V DC supply feed to the
24V and 0V terminals.
Use cables of sufficient size to ensure that the
power input voltage is maintained under all
supply conditions
– refer to the specification
section.
Dual terminal screws are provided so that, if
required, the DC Power can be routed on to
another peripheral unit.
Must be
earthed
Connect the incoming power
supply earth wire to the earth
stud in the back box.
Note: The power supply used MUST BE
designated a Safety Extra Low Voltage (SELV)
supply.
1.2 Fault Input
The “FAULT INPUT” terminals are normally
used to monitor the “normally closed” contacts
of the fault relay output from the power supply.
A 10KΩ series resistor should be connected to
the relay terminals.
If more than one module is powered from the
same power supply, it is only necessary to
connect the fault output monitoring to one of
the modules.
Should no fault relay be available, or if the
monitoring of an external fault signal is not
required, these two terminals should be shorted
together with a 10KΩ resistor across the
terminals of the “FLT-INPUT” terminal block.

1.3 Network Connections
Connect the 2 core twisted pair network data
cable to the A and B terminals.
Connect the data cable screen to the network
SCN terminals. Note that special screen
termination circuits are included on the circuit
card to prevent mains frequency earth-loop
currents flowing between network nodes.
The data cable screen MUST NOT be
connected to any other earth point.
