• At operating temperatures = 60 °C a
long contact (approx. 3s) of the skin
with the surface of the machine/valve
may cause burns (DIN EN ISO 13732-
1).
• At operating temperatures
55 °C – 60 °C a long contact (approx.
3S to 10s) of the skin with the sur-
face of the machine/valve may cause
burns (DIN EN ISO 13732-1).
CAUTION
Self-loosing components!
Components and fasteners may become
loose if not properly installed.
• Observe the information on tightening
torques in this operating manual.
• Check the tightening torque of screw
connections and tighten with the
torque wrench, if necessary.
CAUTION
Noise!
(only for pneumatic actuator)
When venting the pneumatic rotary actua-
tor, noise can be hazardous to health.
• Use silencer at vent port or take other
personal protection measures.
2.7.3 Dangers when used in
explosion-protected areas
DANGER
Danger of explosion!
An explosion can occur if the following
protective measures are not observed:
• Establish an internal electrically con-
ductive equipotential bonding be-
tween the rotary actuator and all metal
mounting parts and the pipeline and
make sure that sufficient lightning pro-
tection is available.
•
Protect the surfaces against inadmis-
sibly high temperatures due to solar
radiation. Shading covers can possi-
bly be required.
•
Protect the actuator against excessive
heating due to heat transfer with hot
media inside the pipeline. If necessary,
mounting kits or shaft extensions are
required.
• Please be aware of that the max.
surface temperature significantly de-
pends on the operating conditions.
Make sure that the actual max. sur-
face temperature is not an ignition
source.
• When selecting the pneumatic valves
and the end position feedbacks, pay
attention to the combination with
Ex-approved products.
• Avoid sparking when using the tool.
