Input for
100-240 VAC
100 to 240 VAC input
Standard AC con¿ guration
12 to 24 VDC Input Wiring Conversion
• If the power source supplied to the system will be 12 to
24 VDC instead of 100 to 240 VAC, disconnect the red
and black output wires from the power supply (Figure 3)
and connect your UL approved limited-energy DC power
supply (Figure 4), using an insulated nylon parallel splice
connector such as T&B part number 2C-12 or equivalent.
• Insert input power wiring into the pre-drilled access hole
on the left side of the electrical box using the appropriate
conduit adapters to maintain the Type 4X rating.
(Customer may have to remove the supplied conduit
connectors.)
• A switch or circuit breaker rated at 5 amps DC shall be
included in the building installation.
• Install the circuit breaker in close proximity to the
equipment and within easy reach of the operator.
• Mark the circuit breaker as the disconnecting device for
the equipment.

100 to 240 VAC Input Wiring
• Open the electrical box by loosening the four corner
screws of the front cover.
• Insert input power wiring into the pre-drilled access hole
on the left side of the electrical box using appropriate
conduit adapters to maintain the Type 4X rating. (Supplied
conduit connectors may have to be removed.)
• Install the input power wires into the proper terminals
on the power supply (Figure 2). Use only 12 to 26 AWG
copper wiring.
• Recommended torque for the terminals is 7 lb-in.
NOTE: When using alternate power supply
7300-7524 (159 000 687):
• Use 10-24 AWG copper wiring, 105 ÛC, torque 4.4 lb-in.

System Input Power
• The panel system is pre-wired with an auto switching power
supply that is rated for 100 to 240 VAC 50/60 Hz input.
• Wire with NEC Class I, 300 volt, 105 C wire.
• A switch or circuit breaker rated at 15 amps AC shall be
included in the building installation.
• Install the circuit breaker in close proximity to the
equipment and within easy reach of the operator.
• Mark the circuit breaker as the disconnecting device for
the equipment.
• Grounding: The protective ground terminal must be
bonded to protective earth in the host equipment.
WARNING
This panel system is
wired for AC voltages
that can injure or kill.
Wiring should be performed by
quali¿ ed personnel only.
Disconnect AC power before opening wiring enclosure.
