4.1.1 AX-ACB Electrical Specifications
AC Branch Circuit Ratings:
120V (1.4A [1 or 2 loop] / 2.8A [4 loop]) – 240V (0.7A [1 or 2
loop] / 1.4A [4 loop]) 50/60Hz
Brown-out – 98V nominal
15A Branch Circuit
Fuse: 5A, 250VAC Ceramic, Time Delay (size 5x20mm)
(Advanced part number 620-003, Bussmann S505-5-R,
Littelfuse 0215005.XP)
AC Wiring: #14 or #12 AWG, refer to NEC
Over-current protection for this circuit must comply with
Article 760 of the National Electrical Code (NEC) and/or
local codes.
The panel must be connected to a
solid earth ground. Use #14 AWG
(2.00 mm
2
) or larger wire with 600
volt insulation rating.
4.1.2 Replacing the AX-ACB AC Board
If replacing the AX-ACB AC board, remove power (AC and battery) from the system. Remove all Molex connector
plugs and the green ground wire plug from the AX-ACB board. Remove the four (4) screws holding the AX-ACB
board to the back box (see figure 4).
Place the new AX-ACB board over the four (4) mounting standoffs and secure with the four (4) removed screws.
Replace the removed Molex connector cables and green ground wire plug, and reconnect AC and battery power.
Failure to tighten the screws will defeat the protection circuitry designed to protect the module from
damage due to lightning and static electricity.
