WARNING: RISK OF EQUIPMENT DAMAGE AND PERSONAL INJURY
!
SEVERAL DIFFERENT SOURCES OF POWER CAN BE CONNECTED TO THIS PANEL. DISCONNECT ALL SOURCES OF
POWER BEFORE SERVICING. THE PANEL AND ASSOCIATED EQUIPMENT MAY BE DAMAGED BY REMOVING AND/OR
INSERTING CARDS, MODULES OR INTERCONNECTING CABLES WHILE THIS UNIT IS ENERGIZED.
2.2.1 AC Power and Earth Ground Connection
Primary power required for the FACP is either 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. Overcurrent
protection for this circuit must comply with Article 760 of the National Electrical Code (NEC) and/or
local codes. Use 14 AWG (2.00 mm
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 TB13 on the FACP, being careful to observe proper con-
nections.
Remove the two keps nuts from the grounding stud in the backbox. Connect the incoming earth ground wire to supplied cable #71073 with a
wire nut. Position the ring terminal end over the grounding stud. Secure with one of the keps nuts. Place the ring terminal from the other sup-
plied ground cable #71073 over the ground stud and secure with the second keps nut. Wire the ground cable to the bottom position of TB11.
Refer to Figure 2.1 on page 21 for location of the stud. Ensure that the ground for AC mains is the first cable installed, closest to the back-
box. 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 (refer to the following section).

2.2.2 Battery Power
The batteries must be sealed lead acid type. Before connecting the batteries to the FACP, make
certain that the interconnect cable between the batteries is not connected. Do not connect the
interconnect cable until the system is completely installed. Observe polarity when connecting
the batteries. Connect the battery cable to J9 on the main circuit board. Refer to "Power Supply
Calculations" on page 125, for calculation of the correct battery rating.
