SE-105 Ground-Fault Ground-Check Monitor Rev. 9
Pub. SE-105-M, November 24, 2005.
NOTES:
1. THE 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.
