Wiring the Console
1. Pull four wires between the power panel and the console; three #14 AWG color-coded wires for AC line (L),
AC neutral (N) and chassis ground; and one #12 AWG (4 mm
2
) green and yellow wire for barrier ground.
For international applications using 240 Vac, pull four wires between the power panel and a 5 A fused,
switched, neon indication spur; three #14 AWG color-coded wires for AC line (L), AC neutral (N) and chassis
ground; and one #12 AWG (4 mm
2
) green and yellow wire for barrier ground. Pull four identical wires be-
tween the spur and the console.
2. Open the right door of the console and connect the four power/ground wires as shown in [Figure 5]. Do not
connect the power wires to breaker panel at this time.

WARNING
The console contains voltages which can be lethal. It is connected to devices
that must be intrinsically safe.
Connecting power wires to a live circuit can cause electrical shock that may
result in serious injury or death.
1. Turn power off at the circuit breaker connecting the power supply wires.
2. Attach conduit from the power panel to the console's Power Area
knockouts only (1 on top and bottom, ref. Figure 4).

POWER WIRING NOTES:
1. Barrier ground must be #12 AWG (4 mm2)
or larger diameter.
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, 2 A 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.
