Connect the HMI to Power
Use the 3-position connector supplied with the HMI to provide power to
the HMI. The power cable for the HMI should be 18AWG, 2-conductor
wire with a shield drain wire and protective shield (foil/braid). Cable (P/N
6030-0009) may be purchased by the foot from Maple Systems for
constructing power cables.
Always run the DC ground wire directly back to the signal return of the
power supply. Do not use the chassis ground wire as the signal return.
Caution: To prevent possible damage to the HMI, wait ten
seconds after removing power from the HMI before applying
power again.
To connect the HMI to power:
1. Route the power cable from the HMI to the power supply. The power
cable should not be any longer than necessary.
2. Install the cable wires, referencing the chart below (with colors
shown for Maple Systems Cable 6030-0009):
a. Strip the power cable shield to expose 2" of the black and red
wires.
b. Strip about ¼" of insulation from the black and red wires.
c. Connect the red wire to the positive (+) input of the HMI power
connector and the 24V DC positive (+) output of the power
supply.
d. Connect the black wire to the negative (–) input of the HMI power
connector and the 24V DC negative (–) output of the power
supply.
e. Connect the power cable shield wire to the HMI power connector
FG or ⏚ input. Connect the other side to chassis ground.

Note: The power connector on the RMI5001 uses a 3-position
terminal block with screw-down clamps. Lugs are not required.
Fusing Requirements
If the HMI does not come on within two seconds of power up, remove
power. An internal solid-state fuse will prevent damage if the polarity of
the DC power is incorrect. Check wiring to ensure proper connections
and try to power up again.
