8 FX20/60 Supervisory Controllers Installation Instructions
Removing and Replacing the Cover
The FX20/FX60 cover is removable. You must remove
the FX20/FX60 cover to connect the battery on a new
unit, to replace the battery on an existing unit or to
install any optional communication cards. The cover
snaps onto the base with four plastic tabs (two on
each end). To remove the cover, press in the four tabs
on both ends of the unit and lift off the cover.
Note: If accessory modules are plugged into the
FX20/FX60, you may need to slide them away from
the unit to get to the cover tabs.
To replace the cover, position it so the cutout area for
the communication ports is correct, then push inward
to snap in place.
