appendix B
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.
Example B – Cabling 50 Feet or Greater, AC Power to Full Wave Bridge
Example A – Cabling Under 50 Feet, DC Power
Example C – Cabling 50 Feet or Greater, AC Power to Power Supply

wire gauge, shield type and
filtering devices used are
dependent on the customer’s
application and system.
NOTE: The length of
the DC power supply
cable to an MDrive
should not exceed 50 feet.
