0 0 <br /> Introduction Permissible Console Interface Module Locations <br /> Wire Gauges-Color coded <br /> ❑ Sensor-and probe-to-monitor wires should be#18,#16,or#14 AWG stranded <br /> copper wire. However,shielded cable is preferred in all applications and is <br /> mandatory on sites using non-bonded metallic or PVC conduit. <br /> ❑ Wires carrying 115 Vac from power panel to Pump Sense Module,Mechanical <br /> Dispenser Interface Module,and Wireless PLLD Controller module should be#14 <br /> AWG copper wire. <br /> ❑ Wires carrying 240 Vac from power panel to Wireless PLLD AC Interface Module <br /> should be#12 AWG copper wire. <br /> ❑ Wires carrying 120 or 240 Vac from the power panel to the console should be#14 <br /> AWG(or larger)copper wire for line,neutral and chassis ground(3); and#12 <br /> AWG copper wire for barrier ground(1). <br /> Sensor and Probe Junction Boxes <br /> Weatherproof electrical junction boxes with a gasketed cover are required on the end <br /> of each probe and sensor conduit run at the manhole or monitoring well location. <br /> Gasketing or sealing compound must be used at each entry to the junction box to <br /> ensure a waterproof junction.The interior volume of each junction box must be a <br /> minimum of 16 cubic inches. <br /> Veeder-Root recommends the following junction boxes or equivalent: <br /> ❑ Appleton Electric Co.-JBDX junction box,JBK-B cover,and JB-GK-V gasket. <br /> ❑ Crouse-Hinds Co.-GRFX-139 junction box,GU-10 cover,and GASK-643 <br /> gasket. <br /> Permissible Console Interface Module Locations <br /> Figure 1 illustrates the permissible probe and sensor interface modules and the <br /> maximum number allowed in each of the three component plug-in areas of the <br /> console:Power Area,Intrinsically Safe Area,and the Communications Area. <br /> Cables to the console's Communication Area modules enter through the large opening <br /> under that compartment and plug in directly to those modules. <br /> i <br /> 5 <br />
