Part No: 4417341 Revision 10
NOTE:
Seal the unused cable inlets with an approved ¾" NPT threaded stopping plug.
WARNING!
Improper installation of cable glands, conduit or stopping plugs will invalidate the Ex

Grounding

The 954 SmartServo FlexLine housing should be properly grounded to the ground
reference (generally the tank).
This is a safety grounding requirement. Grounding can be performed by copper strips
across the flanges (refer to section Grounding at mechanical installation), or by a ground
wire.
With last mentioned method, use one of the external ground terminals of the 954
SmartServo FlexLine.
NOTE:
Grounding shall be performed in accordance with local regulations.
CAUTION!
Safety depends on proper grounding. Check the resistance of the ground connection
directly after installation. The measured ground resistance shall be below the maximum
prescribed by local grounding requirements.
WARNING!
When measuring the ground resistance, use a suitable explosion-proof tester.
