Examination of the O-ring
The O-rings of the transmitter and the cable glands have to be checked regularly as well as after each opening of the
housing for possible damages. Porous or damaged O-rings have to be replaced. Cable glands with defective O-rings have
to be replaced.
Use original spare parts only. Store the O-ring replacement in a hermetically sealed and dark place.
Housing with increased safety
Defective O-rings have to be replaced.
Danger!
Risk of explosion when using the transmitter in explosive atmospheres
This may result in personal or material damage or dangerous situations.
→ The O-rings form part of the ignition protection and have to ensure tightness of the housing to
guarantee explosion protection.
Important!
O-rings of increased safety housings may only be replaced by qualified FLEXIM personnel.
