Internal Power (Battery Power)
All 900CDP Series Digital Meters are battery powered. The battery tray is located behind
the faceplate (see illustration page 8). Power is supplied by two alkaline "AA" batteries.
With normal use, these batteries should provide 2 – 4 years of service. The digital display
has an integral warning of low battery level (see page 6 for details).
WARNING! To reduce the risk of explosion DO NOT mix old batteries with new
batteries, or mix batteries of different manufacturers.
WARNING! Batteries may ONLY be replaced with the following:
Incorrect battery selection presents a safety hazard.
External Power
900CDP Series Digital Meters can use an external power source to operate. Regardless
of the source (AC or DC), external power MUST be routed through the Intrinsically
Safe Barrier any time the meter is installed in an explosive atmosphere. External
power sources MUST be within the rated parameters of the intrinsically Safe Barrier
and meter.
External AC Power
External AC power CANNOT be applied directly to the 900CDP meter. It must be
routed through the Intrinsically Safe Barrier regardless of meter installation location.
The 900CDP Meter is not designed for direct AC power input. See Intrinsically Safe
barrier wiring information on page 12 for additional information.
External DC Power
The 900DP meter can be powered directly by an external DC power source (such as a
Fuel Managment System) that operates within the meters parameters. The Intrinsically
Safe Barrier MUST be used anytime the meter is installed in an explosive atmosphere.
For additional information on non-barrier installations, see page 13.
