Basic guidelines
5265349259-2
Installation (recommendations)
For hydraulic applications: Vertical with the pressure connection pointing upwards
For pneumatic applications: Vertical with the pressure connection pointing downwards
In order to prevent mechanical damage when dealing with critical applications involving heavy vibra-
tions or blows, for example, we recommend securing the unit with an elastomer clamp and decoupling
the hydraulic ports via a Minimess hose.
Screw in the device using a suitable open-end wrench (wrench size see ▶Sec. 10.2 "Dimensions") at
the hexagon of the pressure connection.
Please observe the recommended tightening torque (▶Sec. 10.1 "Technical data")
NOTICE
u Do not install the device by gripping the housing, as this would damage the housing or the entire unit.
Electrical connection
When using hose mounting the housing has to be grounded separately.
In order to reduce the effect of electromagnetic interference:
– Make line connections as short as possible.
– Use shielded lines (e.g. LIYCY 4 x 0.5 mm²)
– The cable shield must be fitted by qualified personnel subject to the environmental conditions and
with the aim of suppressing interference.
NOTICE
u Keep the unit well away from the electrical supply lines of power equipment, as well as from any
electrical or electronic equipment causing interference.
5.2
Mounting the device
723605387-2
1. Installing the sensor directly into the hydraulic system via the threaded connection.
2. Connecting the sensor according to instructions (▶Sec. 10.3 "Terminal connections")
3. Make sure the block is grounded via the hydraulic system.
The sensor itself does not have to be grounded, except when using hose mounting.
