Revised August-2017
In these circumstances, remove the battery charger module (part
W38231X0032) and use the FB103 or FB104 without internal power
batteries. Refer to Section 3.5.3, Replacing the Batteries, for instructions
on removing the battery charger module or contact Remote Automation
Solutions LifeCycle Services for assistance in removing the battery
charger module.

Determining Battery Requirements

To determine the system capacity requirements, multiply the system
current load (I ) on the batteries by the amount of reserve time
SF
required. Compute "I
Requirements. The equation is as follows:
System Requirement = I

Replacing the Batteries

The battery pack contains three D-size lead-acid batteries providing 2.5
Amp-hours of current at 6.2 volts nominal.
When installing equipment in a hazardous area, ensure that all
components are approved for use in such areas. Check the product
