INSTRUCTIONSDANGER

To prevent the risk of explosion, observe not only the safety
instructions in the Operating Instructions for operation in theEx-area, but also the following:▶ Observe information on temperature class, ambient temperature, protection rating, torque and voltage.
▶ Do not use the product in areas where there is gas or dustwith a lower ignition temperature than indicated on the labelfor Ex-area.
▶ Installation, operation and maintenance must be performedby qualified technicians only.
▶ Observe the applicable safety regulations and the applicablenational safety regulations as well as the general rules oftechnology for installation and operation.
▶ Do not repair the product yourself, but replace it with anequivalent product.
▶ The product must only be repaired by the manufacturer.
▶ Do not expose the product to any mechanical or thermal
stresses which will exceed the limits that are given in theOperating Instructions.

6English

DANGER
Risk of explosion when removing a connector.
▶ Secure the M12 female connector. Observe the recommendations that are given by the manufacturer of the female
connector.
▶ Before removing a connector de-energize the product.
Risk of explosion when opening the product.
▶ Only open the product if no Ex-atmosphere is present.
▶ Before product commissioning, tightly close the product andmake sure the covers are locked. A cover is locked if you
cannot open it without the magnetic unlocking key.
Risk of explosion due to electrostatic discharge.
In the event of a sudden discharge, electrostatically charged
products or persons present a risk of explosion in the Ex-area.
▶ Make sure that no electrostatic charging can occur in theEx-area.
▶ To clean the product surface, gently wipe the surface with adamp cloth or anti-static cloth.
Risk of explosion if the product is not connected to theearth.
▶ To earth the product, observe the requirements of standard
IEC 60079-14 and local regulation.
▶ To earth the product, use the external earthing screw.
