Wiring the Console <br /> The console contains voltages which can be lethal. It is connected to <br /> devices that must be intrinsically safe. <br /> ® Connecting power wires to a live circuit can cause electrical shock <br /> that may result in serious injury or death. Routing conduit for power <br /> wires into the intrinsically safe compartment can result in fire or <br /> explosion resulting in serious injury or death. <br /> 1. Turn power off at the circuit breaker connecting the power supply <br /> wires. <br /> 2. Attach conduit from the power panel to the console's Power Area <br /> knockouts only(2 on top and bottom, ref. Figure 2). <br /> 1. Pull four wires between the power panel and the console;three#14 AWG or larger <br /> color-coded wires for AC line(hot),AC neutral and chassis ground; and one#12 <br /> AWG wire for barrier ground. <br /> 2. Connect the power wires to the console as shown in Figure 3. <br /> AC Line(hot) <br /> AC Neutral <br /> Chassis Ground <br /> Barrier Ground <br /> (#12 AWG or larger) <br /> tA,250V Fuse,3AG SLO BLO <br /> Rigid Conduit <br /> (enters Through <br /> a Power Area �'— - -- — — Top of <br /> knockout) Console <br /> N Lf <br /> � wsF <br /> ♦ ®® O <br /> Use ground lug <br /> closest to conduit POWER MODULE <br /> entry <br /> 4 4 <br /> POWER AREA INTRINSICALLY <br /> POWER WIRING NOTES: SAFE AREA <br /> 1.Barrier ground must be#12 AWG or larger. <br /> 2.Check to be sure that the electrical resistance between the console ground <br /> lug and a known good earth ground is less than 1 ohm. <br /> 3.Connect the power supply wires in the power panel to a separate dedicated circuit. <br /> 4.Electrical rating power input—120 Vac or 240 Vac,50/60 Hz,100 W maximum. <br /> 5.See the"Console Dimensions and Designated Conduit Knockouts"(Figure 2)for <br /> actual locations of power conduit knockouts into the console. Power wiring <br /> must enter only in Power Area conduit knockouts. <br /> Figure 3. Wiring AC Power to the Console <br /> 9 <br />
