3.2.1 Opening the Enclosure
The front panel of the harsh enclosure T72XW terminal is locked in place by six spring clips attached to
the body of the enclosure. In order to replace the hardware inside the indicator one need to separate the
front panel from the enclosure as follows:
1. Insert the tip of a flat-blade screwdriver into one of the two slots located on the bottom of
the front panel assembly (see Figure 3.1). While squeezing the front panel and
enclosure together, gently push the screwdriver in toward the enclosure. A “pop” sound
is made when the cover clip is released

2. Repeat Step 1 for the other slot.
3. After releasing the two clips securing the bottom of the front panel, move the panel to each side
to disengage the side clips, then lift the bottom of the front panel firmly up and out (Figure 3-2)
until it completely clears the top edge of the bottom enclosure.
4.
Squeeze the top of the front panel to the enclosure along the top edge slightly and push upward
(Figure 3-2) to unsnap the top two clips, then lift the cover to clear the two top clips. The cover will
swing down, hinged by two wire cables at the bottom.
