Wiring the Console
1. Check the Input Power Rating on the label affixed to the underside of the console to verify whether input
power requirements are 120 Vac or 240 Vac.
2. Pull four wires between the power panel and the console; three #14 AWG or larger color-coded wires for AC
line (hot), AC neutral and chassis ground; and one #12 AWG wire for barrier ground.
3. Depending on the console, connect the input AC power wires as shown in Figure 7 or Figure 8.

WARNING
This console contains high voltages which can be lethal. It is also connected
to low power devices that must be kept intrinsically safe.
1. Turn power Off at the circuit breaker. Do not connect the console AC
power supply wires at the breaker until all devices are installed.
2. Attach conduit from the power panel to the console's Power Area
knockouts only.
Connecting power wires to a live circuit can cause electrical shock that may
result in serious injury or death.
Routing conduit for power wires into the intrinsically safe compartment can
result in fire or explosion resulting in serious injury or death.

POWER WIRING NOTES:
1. Barrier ground must be #12 AWG or larger.
2. Check to be sure that the electrical resistance
between the console ground lug and a known
good earth ground is less than 1 ohm.
3. Connect the power supply wires in the power
panel to a separate dedicated circuit.
4. Electrical rating power input -- 120 Vac or
240 Vac, 50/60 Hz, 100 W maximum.
5. See the "Console Dimensions and Designated
Conduit Knockouts" figure for actual locations of
power conduit knockouts into the console. Power
wiring must enter only in Power Area conduit
knockouts.
