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.
