wires to the enclosure from the power supply and controller. If the
EX-5175-EC
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.
