2.3 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.
2.3.1 AC Power and Earth Ground Connection
Primary power required for the FACP is 120 VAC,
60 Hz, 3.0 amps for the MS-9200UDLS or 240
VAC, 50 Hz, 1.5 amps for the MS-9200UDLSE.
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
2
) 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 TB11
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 in
the building. Refer to Figure 2.1 on page 45 for location of the stud. 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).
2.3.2 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
J9 on the main circuit board. Refer "Power Supply Calculations" on page 187, 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.
2.3.3 Special Application DC Power Output Connection
All Special Application DC power outputs are power-limited (refer to "UL Power-
limited Wiring Requirements" on page 53).
