1.5 Wiring
1.5.1 Basic Wiring
The MCP has many control modes and each mode may have unique wiring requirements
to ensure safe and reliable operation. The diagram below illustrates a very basic wiring
conguration used in a small motor system where safety concerns are minimal. This is the most
basic wiring conguration possible. Any wiring of MCP controllers should include a main battery
shut off switch, even when safety concerns are minimal. Never underestimate a motorized
system in an uncontrolled condition.
In addition, the MCP is a regenerative motor controller. If the motors are moved when the
system is off, it can cause potential erratic behavior due to the regenerative voltages powering
the system. A return path to the battery should always be supplied if the system can move
when main power is disconnected or a fuse is blown by adding a power diode across the shut off
switch.
Never disconnect the negative battery lead before disconnecting the positive!
