7.7.2 Installing the valve in the system
WARNING
Faulty installation of plug screws and lines!
Improperly fastened plug screws and lines may become loose during subsequent
operation and may be ejected due to the pressure. This may cause severe injuries!
▶
Only pressurize your system after all plug screws and lines have been completely
and properly mounted according to the specification.
Faulty mounting!
Mounting of the valve with valve mounting screws of reduced stability, insufficient
mounting or fastening at blocks and plates with insufficient stability may lead to the
valve becoming loose and falling down. Consequently, hydraulic fluid may leak and
lead to personal injuries and/or damage to property. Particular caution applies to
valves with suspended installation.
▶
Completely assemble the valve according to the assembly specifications by
means of suitable assembly aids.
▶
Only assemble the valve at blocks or plates suitable for the weight of the valve.
▶
Observe the tightening torques, screw stability and the minimum length of the
valve mounting screws.
Explosion hazard!
If the valve is used as a device of category 1 in zone 0, the following requirement
must be met. In case of non-compliance, explosion protection is no longer ensured!
▶
The valve cap is made of die-cast aluminum. For the use as a device of category
1 in zone 0, the valve cap must be protected in a way that ensures that even
in case of rare operating failures, no explosive sparks from friction, impact or
grinding can occur.
CAUTION
Insufficient installation space!
Insufficient installation space may lead to jamming or abrasions in case of work at
the valve.
▶
Provide for sufficient installation space.
▶
Ensure that there is enough space so that the valve itself does not have to be
disassembled to remove the mating connector from the valve, if required.
▶
Ensure that there is sufficient clearance area for overpressure protection
at the
valve cap at the connector.
Leaking hydraulic fluid!
Hydraulic fluid may leak during assembly and disassembly of the valve.
Consequently, persons may slip or fall.
▶
After the disassembly, provide the bores containing the hydraulic fluid with
suitable closing elements.
▶
Immediately remove hydraulic fluid that has leaked out.
