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

BATTERY

 

 

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 27 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).

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 and require a ferrite bead per FCC requirements (refer to "UL Power-limited Wiring Requirements" on page 35).

Power-limited Resettable or Nonresettable Power

0.5amperes max., 24 VDC nominal filtered, resettable or nonresettable power can be drawn from TB1 Terminals 1(+) and 2(-)

Power-limited Resettable Power

0.5amperes max., 24 VDC nominal filtered, resettable power can be drawn from TB1 Terminals 3(+) and 4(-)

JP4 is used to configure TB1, Terminals 1 & 2 for:

•Resettable Power - jumper pins 1 and 2 of JP4 as shown

•Nonresettable Power - jumper pins 2
