Recommended Power and Cable Configurations
Cable length, wire gauge and power conditioning devices play a major role in the performance of your MDrive.
Example A demonstrates the recommended cable configuration for DC power supply cabling under 50 feet
long. If cabling of 50 feet or longer is required, the additional length may be gained by adding an AC power
supply cable (see Examples B & C).
Correct AWG wire size is determined by the current requirement plus cable length. Please see the MDrive Sup-
ply Cable AWG Table at the end of this Appendix.
