3.2 Wiring the EX-5130-IS to a Control Unit
C AUTION : Area must be declassified during installation.
Run conduit and 16 AWG (1.5 MM 2 ) wires to the enclosure from the power supply and controller. If the EX-5130-IS is
installed in a hazardous location as defined by the National Electrical Code, then ALL wiring must be in accordance
with the National code and any local governing codes.
Open the enclosure, and remove the 2 screws that retain the display overlay to the circuit board.
Use caution when removing the over lay. Do not damage the magnetic switches.
Remove the two overlay standoffs and remove the circuit board, exposing the terminal strips on the bottom of the
circuit board. Do not disconnect the circuit board wiring.
Connect the wires from the controller (power supply) to the supplied J4 plug then attach to J4 terminal.
Connect the wires from the sensor to the supplied J8 plug then attach to the J8 terminal.

It is recommended that the auxiliary
alarm be powered separately.
Use 14 – 20
AWG (2.5 – 0.5 MM

N OTE : Auxiliary alarms should be powered from an
independent power source separate form the
instrument power to avoid alarm failure due to
controller malfunction.
All wiring must be in accordance with the
National Code and any local governing codes.
