WARNING: RISK OF ELECTRICAL SHOCK AND/OR EQUIPMENT DAMAGE
!
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.
Primary Power Source (AC) and Earth Ground Connections
AC power connections are made inside the control panel cabinet. Refer to AC Power in the section titled "Specifications" on page 13,
for power and current requirements for each FACP version. Run a pair of wires (with ground conductor) from the protected premises
main breaker box to the AC terminal block TB1 on the main power supply. As per the National Electrical Code, use 14 AWG (2.00 mm
1.6 mm O.D.) or heavier gauge wire with 600V insulation. No other equipment may be connected to this circuit. In addition, this circuit
must be provided with overcurrent protection and may not contain any power disconnect devices. An Earth Ground connection must be
made to ensure proper panel operation and lightning and transient protection. Connect the Earth Ground wire [minimum 14 AWG (2.00
mm )] to the grounding stud in the backbox and then run the wire to TB1. Do not use conduit for the Earth Ground connection since this
2
does not provide reliable protection.
Secondary Power Source (Batteries)
