Primary power required for the FACP is 120 or 240 VAC, 50/60 Hz, 3.25 amps. The FACP will auto-detect the voltage used. No special switch or jumper is required to select AC power. Over- current protection for this circuit must comply with Article 760 of the National Electrical Code (NEC) and/or local codes. Use 14 AWG (2.00 mm2) or larger wire with 600 volt insulation rating. Make certain that the AC mains circuit breaker is off before wiring any connections between the mains and the control panel. Connect wiring from the AC mains to TB8 on the FACP, being care- ful to observe proper connections.
Remove the two keps nuts from the grounding stud in the backbox. Connect the incoming earth ground wire to the supplied cable with a wire nut. Position the ring terminal end over the ground- TB8 AC Power Connection ing stud. Secure with one of the keps nuts. Place the ring terminal from the other supplied ground cableover the ground stud and secure with the second keps nut. Wire the ground cable to the bot- tom position of TB11.
Ensure that the ground for AC mains is the first cable installed, closest to the backbox. This connection is vital in reducing the panel’s susceptibility to transients generated by lightning and electrostatic discharge. Apply AC power to the panel only after the system is completely installed and visually checked.
Note that AC power must be applied to the panel before installing the battery interconnect cable.
