Electrical Precautions
MOTOR CONNECTIONS - DO NOT CONNECT OR DISCONECT ANY MOTOR WIRE
CONECTORS WHILE YOUR CONTROL BOX IS TURNED ON !! During the process of a
‘hot’ connect or disconnect there is a high load put on the motor driver circuitry which is
very likely to damage the motor driver. A damaged driver means that motor does not run
correctly. Also, do not unwrap the heat-shrink surround that keeps your motor cables
connected to the motors. It is intended to help keep all connections permanently secure.
STATIC DISCHARGES – Electronic circuits are very sensitive to static and power surges, and
your Control Box is no exception. Please have your electrician follow the wiring and
grounding instructions in the wiring section to help prevent static from damaging
components of your tool. In particular, avoid doing any vacuuming around your tool before
you have grounded both the tool and your vacuum system. Large static build-ups can occur
inside a vacuum collection system and discharge accidentally through the wiring of your
ShopBot.
INDUCED CURRENTS - The stepper motors on your tool become significant little generators
if they are manually turned. They can generate sizable voltages in your control box if you
push the X or Y-axis of your tool around physically. Occasionally it may be necessary to
move the tool by hand, but try to minimize such movement and when you must do it, make
the move slowly. If you need to do a lot of manual movement, unplug the motors on the
axis you are moving - having shut down the power first as noted above.
