INSTALLATION

5.1 Safety instructions

DANGER!
Danger – high pressure in the equipment.
▶ Before loosening the lines and valves, turn off the pressure and
vent the lines.
WARNING!
Risk of injury from improper installation.
▶ Installation may be carried out by authorised technicians only and
with the appropriate tools!
Risk of injury from unintentional activation of the system and an
uncontrolled restart.
▶ Secure system from unintentional activation.
▶ Following installation, ensure a controlled restart.
The add-on dimension must not fall short of 4.5 mm!
→
Insert the sealing gasket into the valve.
→
Correctly allocate the fluid connection configuration 1, 2 and 3 to
the valve and the manifold.
→
Screw valve onto the manifold.

5.2 Fluid Installation

DANGER!
Danger – high pressure in the equipment.
▶ Before loosening the lines and valves, turn off the pressure and
vent the lines.
Installation position: any, actuator preferably upwards.
Procedure:
→
Before installation, clean any possible dirt off the pipelines and
flange connections.
→
Install a dirt trap to prevent malfunctions (Mesh size:
5 µm).
WARNING!
Danger through spillage of medium.
Leaking connections if seal seated incorrectly.
▶ Ensure that the supplied sealing gasket is seated correctly.

5.3 Electrical Installation

NOTE!
Without proper power reduction electronics, the valve type 6650
is not suitable for continuous operation! Please refer to the
chapter titled "4.5 Electrical data".
In the block structure all valves must be poled identically. The
mark (+) on the valve and the numerals 1 and 2 on the plug-in
connector are used as orientation. Example: On all units the
plug-in connector with numeral 2 points to the mark (+).
