Batteries (also see 'Installation')
Batteries must be tted to the Electronics Module to make sure the DRV switches
to Full Cold in the event of a primary power supply failure, they should not be
considered to be a backup power supply.
Battery life is variable depending upon usage. A battery error message appears on
the DRV display when they require replacing.
Where primary power supply failure occurs regularly or the DRV is installed within a
supply system where safety is critical, the batteries must be changed at least every
12 months as part of an annual maintenance routine.
In noncritical systems or where battery usage is low, longer replacement cycles
may be considered up to a maximum of 5 years. Inspection of critical components
and/or assemblies.
CAUTION!
RISK OF FIRE OR PRODUCT DAMAGE IF INCORRECT TYPE OF BATTERY IS FITTED.
