Installing the MPC Open XP
500mA - ((max. expected temp. - 115°F) * 8mA/F)
Output wiring specifications
To size output wiring, consider the following:
•
Total loop distance from the power supply to the controller, and then to the controlled device
NOTE Include the total distance of actual wire. For 2-conductor wires, this is twice the cable length.
•
Acceptable voltage drop in the wire from the controller to the controlled device
•
Resistance (Ohms) of the chosen wire gauge
•
Maximum current (Amps) the controlled device requires to operate
To wire inputs and outputs
WARNING Do not apply line voltage (mains voltage) to the controller's ports and terminals.
The following applies to the inputs and outputs on the MPC Open XP and expanders.
1
Verify that the MPC Open XP's power and communications connections work properly.
2
Turn off the MPC Open XP's power.
