    Make sure the surface of the O-ring grooves of the housing are clean and the O-rings are not damaged before assembling the lids to the 954 SmartServo FlexLine housing. Make sure that the both lids (used for terminal block and board compartments) do not squeeze any cables during the assembly.

  • Page 40: External Fusing

    NOTE: If the 954 SmartServo FlexLine is installed in a hazardous area, Ex d certified conduit seals must be applied directly at the wall of the 954 SmartServo FlexLine to seal the cabling in the conduit. Depending on the wiring configuration, one to four ¾” NPT threaded cable glands (or rigid conduits) may be required with the 954 SmartServo FlexLine.

  • Page 41: Grounding

    Improper installation of cable glands, conduit or stopping plugs will invalidate the Ex approval of your 954 SmartServo FlexLine. 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.
