Wiring Tips
• Use a grounded or shielded metal conduit for
power cabling.
• Use the shortest possible cables or wires for
incoming power.
• Use the shortest possible cables or wires between
the controller and the motor.
• Route low-voltage cables away from high-power
cables or wires or other known electromagnetic
interference EMI sources. If cables must cross,
cross at a 90° angle.
• The Graco Motor Control used with BLDC motors
has an integrated line filter, so no external filter is
necessary.
