WARNING
Unsuitable cables, cable glands and/or plugs
Risk of explosion in hazardous areas.
• 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 specied in Technical specications
(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 rmly.
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 specications > 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.
NOTICE
Condensation in the device
Damage to device through formation of condensation if the temperature dierence between
transportation or storage and the mounting location exceeds 20 °C (36 °F).
