CAUTION:
Several different sources of power can be connected to this
panel. Disconnect all sources of input power before servicing. While
energized, the control panel and associated equipment can be damaged by
removing and/or inserting cards, modules, or interconnecting cables.
CAUTION:
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 skin or eyes with water for 15 minutes and seek
immediate medical attention.
Primary power required for the control panel is 120 VAC or 240 VAC,
50/60 Hz, 3 amps. Overcurrent protection for this circuit must comply with
Article 760 of the National Electrical Code (NEC) and/or local codes. Use
#14 AWG or larger wire with 600 volt rating.
Observe polarity when connecting batteries. Connect the battery cable to
TB1 on the power supply board. Refer to Power Supply Calculations for
information on determining the correct battery rating. AC and battery wiring
are not power limited. Maintain at least 0.25 in. between power limited and
nonpower limited wiring.
