3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any contin-
gencies and events which may arise during installation, operation
and maintenance.
Risk of injury from high pressure.
▶Before loosening lines or valves, switch o the pressure and
drain the lines.
Risk of injury due to electric shock.
▶Before reaching into the device or the system, switch o the power
supply and secure to prevent reactivation! Observe the applicable
accident prevention and safety regulations for electrical devices.
Risk of burns or risk of re.
Continuous operation or hot media may result in a hot device
surface.
▶Keep the device away from highly ammable substances and
media and do not touch with bare hands!
▶Do not obstruct heat dissipation required for operation.
Risk of injury due to cold, hot and aggressive media.
Heat sources or temperature uctuations may cause malfunctions
or leaks.
▶Avoid heat sources which may cause the permissible tempera-
ture range to be exceeded.
▶Check the media resistance before use.

Danger due to low and high temperatures.
Depending on the media temperature, the device can become
extremely cold or extremely hot.
▶Keep the device away from substances sensitive to cold and
highly ammable substances and do not touch with bare
hands.
Destruction of the coil due to overheating
▶Electrically connect coil with mounted housing only.
▶In the case of alternating voltage, pay attention to movable
core.
▶Check media resistance.
General hazardous situations.
To prevent injuries, ensure that:
▶Do not feed in any aggressive or highly ammable media.
▶Do not make any internal or external changes to the device.
▶Secure the system and device against accidental activation.
▶Installation and maintenance may only be performed by autho-
rised technicians only using the appropriate tools.
▶After an interruption in the power or pneumatic supply, ensure
that the process is restarted in a dened or controlled manner.
▶Do not mechanically load housing.
▶Observe the general rules of technology.

→Screw cable plug tightly onto the coil
(max. 1 Nm).
Only for variant with terminal connection box:
•Connect a maximum of one conductor per terminal point
•The maximum connection cable cross-section is 2.5 mm² / AWG 14

5.3 Rotating the solenoid
WARNING!
Risk of injury due to electric shock.
If there is no protective conductor function between the coil and
body, there is a risk of electric shock.
