•
For capacities greater than 18 Ah, the batteries require a BATB-40 Battery Case. Connections between the
batteries in the Battery Case and the control panel must be in conduit and be no more than 20 ft (6.1 m)
from the control panel. All power wiring must exit from the left side of the FPP-RNAC-8A-4C enclosure.
•
Battery wires must be 12 AWG (2.3 mm).
•
The FPP-RNAC-8A-4C provides a regulated output voltage of 24.1 VDC (500 mV ripple maximum) when
operating from the standby batteries under all conditions, including when the batteries are nearly depleted.
•
A low battery condition is reported when the battery voltage drops below 20.4 V for the pair.
•
The FPP-RNAC-8A-4C fully charges depleted 40 Ah batteries within 48 hr.
•
A disconnected battery indicates its state within 1 min.
