3 AUTHORIZED USE
Incorrect use of the electropneumatic positioner Type 8635 can
be dangerous to people, nearby equipment and the environment.
▶The electropneumatic positioner is designed to be mounted on
pneumatic actuators of process valves for the control of media.
The device was designed for the use in
- Type 8635 PE68:
Explosion group II, category 2G Ex ia, T4, T5 and T6
(see information listed on the type label for the approval).
▶The device is mounted onto a pneumatic actuator of a process
valve. The process valve and the actuator must have at least the
Ex approval of the pneumatic control unit.
▶During use observe the admissible data, the operating condi-
tions and conditions of use specified in the contract documents,
operating instructions and on the type label
- of the electropneumatic positioner Type 8635 and
- the process valve.
▶Use the device only in conjunction with third-party devices and

4 PARTICULAR SAFETY
INSTRUCTIONS
Danger!
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.
▶Clean the plastic surfaces with the body being open only by slightly
wiping them with an antistatic cloth.
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 type label for the approval.
▶Do not use devices in areas where there is gas with a lower igni-
tion temperature than indicated on the type label for the approval.
▶Installation, operation and maintenance may be performed by
qualified technicians only.
Danger!
▶Observe the applicable safety regulations (also national safety
regulations) as well as the general rules of technology for con-
struction 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.
