Replacing equipment
Note: To disconnect the power plug, you must press a latch trip on the
front and rear of the plug. You may need to use a screwdriver blade
against the latch trip on the front of the plug.
6 Tag and disconnect cables to the NT8D22 System Monitor. Loosen the
two screws on the system monitor card and remove it from the PDU.
7 Remove the six screws that position the PDU. Carefully pull the unit
straight forward and set it on the floor next to the pedestal (see
Figure 12).
The PDU cannot be completely removed from the pedestal until cables
to the field wiring terminal block are disconnected. Label wires
carefully. Improper wiring can cause system damage.
