Recommended Power and Cable Configurations
Cable length, wire gauge and power conditioning devices play a major role in the performance of your MForce
PoweDrive.
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 Table 2.2.1 for
recommended wire gauges.
