SECTION 14. INSTALLATION AND MAINTENANCE

14.11 MAINTENANCE

The CR10 Wiring Panel and power supplies
require a minimum of routine maintenance.
When not in use, the PS12LA should be stored
in a cool, dry environment with the AC charging
circuit activated.
The PS12ALK alkaline supply should not drop
below 9.6 V before replacement. When not in
use, remove the eight cells to eliminate
potential corrosion of contact points and store
in a cool dry place.
The CR10 module is sealed and contains
desiccant to protect against the vagaries of
humidity. The Wiring Panel and the
connections between the Wiring Panel and the
CR10 are still susceptible to humidity. To
prevent corrosion at these points, additional
desiccant must be placed inside the enclosure.
If only alkaline batteries are inside the
enclosure, the sensor lead entrance may be
plugged to inhibit vapor transfer into the
enclosure. Do not plug the entrance if lead acid
batteries are present. Hydrogen gas generated
by the batteries may build up to an explosive
concentration.
