Figure 6.63 – 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.
