Verify the mounting surface for the valve. Uneve-
ness of 0.01 mm/100 mm, surface finish of 6.3
µm are tolerable values.
Keep clean valve mounting surface and work
environment!
Remove protection plate from the valve mounting
surface
Check the proper position of the valve ports and
the O-rings.
Mounting bolts:

Insufficient condition of the valve mounting
surface migth create malfunction! Incorrect
mounting resp.bolt torque may result in abrupt
leakage of pressure fluid on the valve ports.
Operation Limits
The valve may be operated within the determined
limits only. Please refer to the “technical data“ sec-
tion as well as to the “characteristic curves“ in the
catalog.
Follow the environmental conditions! Unal-
lowable temperatures, shock load, aggresive
chemicals exposure, radiation exposure, il-
legal electromagnetic emissions may result
in operating trouble and may lead to failure!
Follow the operating limits listed in the
“specifications“ table!
Pressure Fluids
The following rules applies for the operation with
various pressure fluids:
This information serves for orientation and
does not substitute user tests among the
particular operating conditions. Particularly
no liabiliy for media compatibility may be
derived out of it.
Mineral oil: usable without restriction.
HFC: choose the right seal option.
For operation with the following pressure fluids
please consult Parker:
For detailed information concerning pressure
fluids note VDMA-document 24317 as well as
DIN 51524 & 51502.
Special gaskets may be available depending on
the utilized fluid.

Electrical Connection
The electrical connection of the valve takes place
by one common cable, which is coupled to the
integrated electronic driver by a central connector
assembly.
The connection Code 0 as well as Code 7 requires
a 6 + PE female connector EN 175201-804.
The female connector has to be ordered
separately under article nr. 5004072.
A female connector with metal housing is
required! Plastic made models may create
function problems due to insufficient EMC-
characteristics.
The connecting cable has to comply to the follow-
ing specification:
Cable type control cable, flexible,
7 conductors, overall braid
shield
Cross section min. AWG16
Outer dimension 8...12 mm
Cable length max. 50 m
For cable lengths > 50 m consult Parker.
The connection cable is coupled to the female
connector by solder joints.
Skinning lengths for the connecting cable:
The connection Code 5 requires a 11 + PE female
connector EN 175201-804.
The female connector has to be ordered
separately under article nr. 5004711.
A female connector with metal housing is
required! Plastic made models may create
function problems due to insufficient EMC-
characteristics.
The connecting cable has to comply to the follow-
ing specification:
Cable type control cable, flexible,
8 conductors, overall braid
shield
Cross section min. AWG16
Outer dimension 12...15 mm
Cable length max. 50 m
For cable lengths > 50 m consult Parker.
The connection cable is coupled to the female
connector by crimp contacts.
Skinning lengths for the connecting cable:
For the workmanlike termination of the crimp
contacts the tool # 932 507-001 – supplier:
Hirschmann – is required.
Do not disconnect cable socket under tension!
The shielding has to be assembled according the
outline below:

Electrical Interfacing
Supply Voltage
The supply voltage for the valve has to cover the
range of 22...30 V. The residual ripple may not
exceed 5% eff.
The applied power supply must comply to the
relevant regulations (DIN EN 61558) and must
carry a CE-mark. The operating voltage for
the valve must be free of inductive surges. Do
not exceed the max. value of 30V! Non-ob-
servance of this rule may result in permanent
damaging of the valve.
The increased inrush current of the valve
should be considered when selecting the
power supply. A stabilized power supply with
overcurrent limiting feature should not be
used. Due to the inrush current of the valve
the current limit circuit may respond prema-
turely and create problems during energizing
of the supply voltage.
The operation of the valve is blocked if the
supply voltage polarity is interchanged.
Each valve requires a separate pre-fuse of 4
Amp time lag.Non-observance of this instruc-
tion may create irreparable damage of valve
resp. incorporated system parts.
The backshell nut of the cable gland has to be
tighten with a suitable tool.The target value for the
tightening torque is 4 Nm. Tighten the cap nut with
a torque of approx.5 Nm after attaching the female
connector on the socket outlet.
Incomplete tightening of backshell nut resp.
cap nut may result in automatic release of the
connection as well as degradation of the
water tightness.
Follow the “instructions for use“ for installation
of female connectors made by other kind of
brands!
The cable connection to the female connector
has to take place by qualified personnel! A
short between individual conductors resp. to
the connector housing , bad soldering as well
as improper shield connection may result in
malfunction and breakdown of the valve.
The mounting surface of the valve has to be
carefully tied to the earth grounded machine
frame. The earth ground wire from the valve
connecting cable as well as the cable shield
have to be tied to the protective earth terminal
within the control unit. It is necessary to use
a low ohmic potential connection between
control unit and machine frame to prevent
earth loops (cross section AWG 6).
