PARTICULAR SAFETY INSTRUCTIONS DANGER!

Risk of explosion when removing the electric circular plug. ▶▶ Secure cable connections, which use circular plugs, with suitable locking clips. For example: EXCLIP, FA. Phoenix Contact, Type SAC-M12-EXCLIP-M, Art. no. 1558988 or Type SAC-M12-EXCLIP-F, Art. no. 1558991 or locking clips, FA. ESCHA locking clip M8 x 1, Art. no. 8040691 locking clip M12 x 1, Art. no. 8040501. ▶▶ Remove electric circular plug only after the power supply has been disconnected. Risk of explosion when opening the device. ▶▶ Open device only when no Ex atmosphere is present. ▶▶ During the installation and setting of the proximity switches, no Ex atmosphere may be present. ▶▶ Prior to start-up, secure the transparent cap against being opened without tools by using the enclosed locking wire. Risk of explosion due to electrostatic discharge. In the event of a sudden discharge from electrostatically charged devices or individuals, there is a risk of an explosion in the explosion-risk area. ▶▶ Ground body casing to visible stainless steel surface before start-up using the supplied clirclip (devices with visible stainless steel surface). 6

English

▶▶ Take suitable measures to ensure that no electrostatic discharges can build up in the explosion-risk area. ▶▶ Clean the device surface by gently wiping it with a damp or antistatic cloth only. DANGER! To prevent the risk of explosion, observe not only the safety instructions in the operating instructions for operation in the explosion-risk area, but also the following: ▶▶ Observe information on temperature class, ambient temperature, degree of protection and voltage on the approval sticker. ▶▶ Do not use devices in areas where there is gas or dust with a lower ignition temperature than indicated on the approval sticker. ▶▶ Installation, operation and maintenance may be performed by qualified technicians only. ▶▶ Observe the applicable safety regulations (also national safety regulations) as well as the general rules of technology for construction and operation. ▶▶ Do not repair the device yourself, but replace it with an equivalent device. ▶▶ Repairs may be performed by the manufacturer only. ▶▶ Do not expose the device to any mechanical and/or thermal loads which will exceed the limits described in the operating instructions. ▶▶ Use only cable and line entry points which have been approved for the respective application area and which have been screwed into place according to the associated installation instructions. ▶▶ The cable glands shall only be used for fixed installations.

BVS 14 ATEX E 008 X / E 052 X Particular safety instructions ▶▶ Close all unnecessary cable glands with lock screws approved for the explosions area. ▶▶ The required degree of protection (min. IP64) is only guaranteed in connection with suitable adaption sets. All pneumatic and electrical connections must be equipped with suitable connectors.
