The ADFM is designed to operate from one of two independent
power sources: internal batteries or external DC power supply.
All sources may be used concurrently; the source that supplies
the highest voltage will automatically supply power to the
system.
The battery configuration consists of four 6-volt alkaline lantern
batteries with spring terminals. Recommended alkaline batteries
have 25Ah nominal capacity. These alkaline batteries have
approximately 2.5 times the power/life of the lead-acid type.
A supply voltage of 24 to 36 VDC is recommended to allow oper-
ation from the internal batteries when the external power supply
is interrupted.
The 24VDC power supply plugs directly into a standard AC
outlet and terminates in a connector compatible with the DC con-
nector on the box or canister controller, or with unterminated
wires if the system includes an accQcomm Interface Module.
This power supply is included with the ADFM system.
This two-conductor pigtail cable provides no grounding. It mates
with the DC connector on the controller. Wire colors for the power
cable are designated as follows:
Pin
(+)1
(-)4
This cable is installed at the factory as part of ADFM systems
that are mounted inside an enclosure with a 24V DIN rail
(example: Figure 2-20).
