It also allows a trailing-cable ground to be monitored in the presence of stray dc and it prevents inter-machine arcing caused by the voltages induced in the cables. PPI-600V Parallel Path Isolator Rev. 0 TYPICAL APPLICATION GROUND CHECK MONITOR SE134C, SE-135, SE-105 OR SE-125 CABLE GROUND G INCOMING GROUND CHECK GC INCOMING GROUND CABLE GROUND GC GC G G INCOMING GROUND-CHECK TERMINATION CHASSIS GROUND BUS OUTGOING GROUND CHECK OUTGOING GROUND OUTGOING GROUND CHECK TERMINATION PPI-600V NOTES: 1. PARALLEL PATH ISOLATOR IS NOT POLARIZED. EITHER FLANGE CAN BE CONNECTED TO CHASSIS. 2. THE OUTGOING GROUND MUST BE ISOLATED FROM THE CHASSIS GROUND BUS. IF A FLANGE-MOUNTED RECEPTACLE IS USED, VERIFY THAT THE FLANGE IS ISOLATED FROM THE GROUND PIN, AND - USE A MATING PLUG WITH A NON-METALLIC HOUSING, OR - ISOLATE THE FLANGE FROM THE CHASSIS IF THE MATING PLUG HAS A METALLIC HOUSING. 3. CABLE PLUGS AND RECEPTACLES WITH GROUNDED METAL HOUSINGS MUST BE ISOLATED FROM EARTH TO PREVENT PARALLEL GROUND PATHS. 4. FOR SYSTEMS ABOVE 600 VAC, CONNECT A V131DA40 MOV ACROSS THE PPI-600V.
