The Meter Module provides a voltmeter to measure the
voltage across the batteries and an ammeter to measure the
charging current to the batteries. The meters are provided as
an assembly that mounts to the lower left-hand corner of the
cabinet.

Dry Form-C contacts rated: 2.0 amps @ 30 VDC (resistive), 0.5 amps @ 30 VAC (resistive). Any
power connected to these relay contacts must come from a power-limited supply. Fail-safe
operation ensures trouble relay functions under loss of both primary power (AC) and secondary
(battery).
