your bare wrist, and then perform the following steps:
1 Unlock the latch pin.
2 Pull down on the locking lever until the BIU or rectifier moves forward and disconnects from its
socket.

To install a BIU or rectifier, first attach a grounding strap from the cabinet to your bare wrist, and then

connectors.
