• Use only cable glands/plugs that comply with the requirements for the relevant type of
protection.
• Tighten the cable glands in accordance with the torques specified in Technical specifications
(Page 43).
• Close unused cable inlets for the electrical connections.
• When replacing cable glands, only use cable glands of the same type.
• After installation, check that the cables are seated firmly.
NOTICE
Torque with NPT screwed gland
Device damage. The maximum torque of the cable gland must not be exceeded.
• To avoid damage to the device, the NPT adapter must be held in place while the NPT gland
is screwed into the NPT adapter. Refer to the section "Technical specifications > Mechanical
construction (Page 45)" for the torque value.
NOTICE
Standard cable gland/torque
Device damage.
• Owing the reasons pertaining to tightness (IP enclosure rating) and the required tensile
strength, only use the cables having a diameter ≥ 8 mm for standard M20x1.5 cable gland,
or use a suitable seal insert in case of smaller diameters.
• In the NPT version, the positioner is delivered with a coupling. When inserting a counter
piece in the coupling, ensure that the maximum permissible torque of 10 Nm is not
exceeded.
