with hydraulic manifolds/modules with electrically controlled valves
High electrical voltage!
With manifold blocks/modules with installation or attachment components with
a supply voltage > 50 VDC or 75 VAC, touching an electric part at the device may
lead to a fatal electric shock.
▶
Manifolds/modules may only be electrically connected by or under the supervi-
sion of a specialized electrician.
▶
Use suitable plug-in connectors and cables.
▶
Switch off the voltage supply before all maintenance, repair or installation works
and secure it against restarting.
▶
Provide for proper, safe PE connection.
▶
Only use power supply units with safe voltage separation. Safe separation can
for example be achieved by means of isolation transformers, safe optocouplers
or mains-free battery operation.
Missing equipotential bonding!
Electrostatic processes, an incorrect earthing concept or missing equipotential
bonding may lead to malfunctions or uncontrolled movements at the machine and
thus cause injuries.
▶
Provide for correct earthing and provide for proper equipotential bonding.
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 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.
▶
Only use the manifold/module within the intended IP protection class or lower.
▶
Ensure before the assembly that all seals and caps of the plug-in connections
are tight and intact.
EMC interference!
Uncontrolled machine movements due to electro-magnetic radiation of unshielded
connection lines.
▶
Observe the EMC limit values.
▶
Only use recommended electrical connection lines according to the EMC
Directive and shield the valve electronics from the source of interference,
if necessary.
▶
Provide for proper earthing.
