Figure 6.66 – Replacement of DC/DC power supply

The replacement of printed circuit boards should be handled in a
careful and deliberate 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 on
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.
