    Safety instructions and measures 1.3 Notes on possible property damage NOTICE Risk of damage to the positioner due to incorrect mounting position. Î Do not mount the positioner with the back of the device facing upward. Î Do not seal or restrict the vent opening when the device is installed on site. An incorrect electric signal will damage the positioner.

  • Page 12: Special Instructions Concerning Explosion Protection

    Safety instructions and measures 1.4 Special instructions concerning explosion protection If a part of the device on which the explosion protection is based needs to be serviced, the device must not be put back into operation until a qualified inspector has assessed it accord- ing to explosion protection requirements, has issued an inspection certificate, or given the device a mark of conformity. Inspection by a qualified inspector is not required if the manu- facturer performs a routine test on the device before putting it back into operation and the passing of the routine test is documented by attaching a mark of conformity to the device.

  • Page 13: Warnings On The Device

    Safety instructions and measures Î Use certified cable glands and blanking plugs with appropriate type of protection and IP rating ≥ 6X and suitable for the certified temperature range. Î To connect the signal circuit, use screw terminals (terminal 11/12) for electrical conduc- tors with a wire cross-section from 0.2 to 2.5 mm². The tightening torque is 0.5 to 0.6 Nm. 1.5 Warnings on the device Warning Meaning of the warning Warning against sudden loud noise The positioner mounted onto the control valve can cause the pneumatic actu- ator to vent. A loud noise may occur during venting. This can cause hearing damage.
