Penetrating water and humidity!
In case of use in humid or wet environments, water or humidity may penetrate
at electrical plug-in connectors or the valve electronics. This case may lead to
malfunctions at the valve and to unexpected movements in the hydraulic system
which may result in personal injury and damage to property.
▶ Do not use the valve with IO-Link interface outside or below its intended
IP protection class.
▶ Ensure before the assembly that all seals and caps of the plug-in connections
are tight and intact.
Easily inflammable hydraulic fluid!
In connection with fire or other hot heat sources, leaking hydraulic fluid mist may
lead to fire or explosions due to defective or incompletely assembled valves and
their connections.
▶ Do not use the valve in areas with open fire and only at a sufficient distance to
hot heat sources.
Electro-magnetic processes!
The valve electronics may be damaged if they are interfered with. This can lead to
uncontrolled reactions at the valve.
▶ Exchange valves with defective electronics right away and replace them with
a new device or original spare parts.
▶ The housing of the electronics serves as shielding from electro-magnetic
interferences. Do not remove the housing of the electronics.
