WARNING
Faulty installation!
If the valve is not correctly mounted, persons might be injured or the product or
system could be damaged when commissioning the valve.
▶ Only commission your system when all hydraulic connections and the valve
have been completely and properly mounted according to the specifications.
▶ Look out for defective sealing points and exchange defective seal rings
immediately.
▶ Wear personal protective equipment during the initial commissioning.
Inadmissibly high operating pressure!
In hydraulic applications with different area ratios, the hydraulic pressure is
fortified and may - in case of incorrect design - lead to an exceedance of the
maximum admissible operating pressure. Thus, the valve may burst or the closing
elements may be ejected and cause personal injury.
▶ Before commissioning the hydraulic system, ensure that the maximum
admissible pressure of the hydraulic valve in the system is not exceeded by
any means.
▶ Ensure that, in your system, the maximum admissible operating pressure is
secured by means of apressure limitation element.
Damage to persons and property!
The commissioning of the valve requires basic hydraulic and electrical knowledge.
▶ Only qualified personnel (seesection 2.4 "Qualification of personnel")
is authorized to commission the valve.
Proceed as described in the following sections to commission the valve:
▶ Have the electrical connections checked for proper condition by or under the
guidance and supervision of aspecialized electrician before the initial
commissioning or any re-commissioning.
▶ If possible, only check the hydraulic functions in acontrolled way and at low
pressure.
For the control and functional test, special test devices are available. Refer to
chapter7.6 "Required accessories".
▶ Ensure that no hydraulic fluid leaks on the valve or on the connections
during operation.
