The replacement of printed circuit boards should be handled in a careful
manner.


There are some basic precautions that should be taken. They include the
following:

Remove all power to the drive.

Do not remove the replacement board from the anti-static bag until

necessary.

Use anti-static wrist strap, grounded in the Low Voltage Control

Section


There are no direct screw/terminal connections on any of the Low Voltage
circuit boards. All wire/terminal connections are made with plugs that
plug into the circuit boards. This means that changing boards only
requires the removal of the plugs, minimizing the chance of mistakes
when reconnecting all of the wiring.
