NOTE!
Electrostatic sensitive components / modules!
The power reduction electronics, which is available as an
accessory, contains electronic components which react
sensitively to electrostatic discharge (ESD). Contact with
electrostatically charged persons or objects is hazardous
to these components. In the worst case scenario, they
will be destroyed immediately or will fail after start-up.
• Observe the requirements in accordance with EN
61340-5-1 and 5-2 to minimize or avoid the possibility
of damage caused by a sudden electrostatic discharge!
• Do not touch live electronic components!

6.5.1. Continuos operation with power
reduction electronics
For the continuous operation of valve type 6650, a power
reduction electronics is required. It is recommended to use
the electronics, which is available as an accessory (see
data sheet).
NOTE!
Malfunction due to overheating!
• If required, use suitable power reduction electronics.
• For a switch-on time >50 s (for single mounting >60 s)
always use a power reduction electronics!
• The electronics 670178, available as an accessory,
are suitable for a nominal voltage of 24 V only.
The following graphs provide a guideline for estimating
whether a power reduction electronics is required. If the
gap between the individual units is <10 mm, use the graph
for the block structure. A power reduction electronics is not
required if the intersection point of switch-on and switchoff time is in the upper area of the corresponding graph.

7. INSTALLATION
7.1. 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!

7.2. 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 pipe-
lines 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!
The add-on dimension must not fall short of 4.5 mm!

7.3. Electrical Installation
NOTE!
Without proper power reduction electronics, the valve
type 6650 is not suitable for continuous operation!
Please refer to the chapter titled "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 (+).
plug-in connector
1 = brown
2 = white
If the power reduction electronics are used, observe
the following polarity: brown + / white -
A type-specific plug-in connector with or without integrated
power reduction electronics is available as an accessory

The valve is maintenance-free under normal operating
conditions.
If the exterior is very dirty, it is recommended to clean it
with suitable cleaning agents. If required, determine the
suitability of the cleaning agent by conducting a test.
WARNING!
Discharge of medium and malfunction if the connection clamps are removed!
• The connection clamps between coil and fluid housing
must not be removed.

If operating with power reduction electronics,
ensure that the power supply flank is quick enough.
If malfunctions occur, check
→ the line connections
→ the operating pressure
→ the power supply and valve control
If the valve still does not switch, please contact your
Bürkert Service.
