8.2.4 Housing Removal
Note: If there is existing wiring connected in any of the four terminal blocks, unplug the terminals and
leave the wiring intact. Note that three blocks are located on the regulation board (top), and one is
located on the power board (bottom).
a. Remove two screws located at the front of the lower board to remove the lower panel and free the
case. (See Figure 8.2.)
Note: If wired, the Protector Earth Ground connector is attached to one of the screws.
b..Refer to the following caution statement before performing this step. To remove the case, carefully
separate the bottom of the housing from the heat sink casting approximately ½ inch to clear the two
mounting bosses and the power board. Gently pull outward and slide upward to disengage the tabs
securing the upper end of housing.
Caution: To avoid breaking off tabs, do not separate the bottom more than one-half inch.
The housing is now free of the base.
