OPTIONAL EQUIPMENT
Battery back-up units for
GasSens
detection systems (part #00-0057) are separate components
housed in a NEMA 4X wall mount enclosure. Back-up units include a 4 ampere-hour sealed lead acid
battery with a control circuit attached to the battery terminals. The battery is held in place on an aluminum
bracket fixed to the plastic enclosure.
Installation
Figure 4-1 shows the dimensions of the battery back-up unit and the mounting hole centers. Two
conduit hubs are supplied with the unit, one for use on the battery back-up enclosure and one for use on
the receiver enclosure.
When mounting the battery back-up unit, be careful to hold the module
securely when screwing the enclosure in place. The battery is heavy and could cause injury to
feet if it should fall directly on them.
The battery and attached circuit board are held in place with a
wire tie. Should you wish to remove the battery, the wire tie must be cut. When replacing the battery,
secure with a new wire tie. Replacement batteries from ATI are supplied with the proper wire tie.
