4 Assembly
The installation of the EDS 3400 is carried out on the fluid side.
The EDS 3400 is mounted via the pressure port as close as possible to
the accumulator (Example: to the left of the diaphragm accumulator via
a safety and shut-off block SAF).
Please also observe the following installation recommendations.
For torque value, see Chapter 18 - Technical data.
Installation recommendation
Safety and shut-off
block SAF
It is recommended to mount the p
0
onto a safety and shut-off
block (SAF) which is usually located close to the hydro
accumulator.
Bladder
accumulator vent
hole
If using bladder accumulators, the vent hole at the oil valve can
also be used. When mounting the p
0
-Guard on the vent hole of
the bladder accumulator, the function of the vent screw is no
longer usable.
Control block
If using accumulator stations (parallel arrangement of the hydro
accumulators), the p
0
-Guard should be mounted onto a central
strip or to a central control block.
To ensure optimal positioning, the unit can be rotated by 340° about its long axis, and the
display and key pad can be rotated by 270°.
The electrical connection must be carried out by a qualified electrician according to the
relevant regulations of the country concerned (VDE 0100 in Germany). The pressure switch
housing must be earthed correctly at the same time. When fitted into a hydraulic block,
earthing the block via the hydraulic system is sufficient.
