2.2 Power
WARNING: 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 120 VAC,
60 Hz, 3.2 amps. 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 mm2) or larger wire with 600 volt
insulation rating. Make certain that the AC mains
circuit breaker is off before making any wiring
connections between the mains and the control panel. Connect the wiring from the AC
mains to TB1 on the FACP, being careful to observe proper connections.
Connect a wire from the grounding stud in the cabinet to a known solid earth ground. This
connection is vital for maintaining the control panel’s immunity to unwanted 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

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 TB2 on the main circuit board. Refer
"Power Supply Calculations" on page 127, for
calculation of the correct battery rating.
WARNING: Battery contains sulfuric acid which can cause severe burns to the skin and
eyes and can destroy fabrics. If contact is made with sulfuric acid, immediately flush the
skin or eyes with water for 15 minutes and seek immediate medical attention.

2.2.3 DC Power Output Connection
