6.2 Mounting/dismounting of the cables
Note
To ensure a reliable contact, only connect one conductor per terminal.
Only insert cables into the terminal opening.
Pushing a screwdriver into the opening may damage the terminal.

7 Earth valve terminal
Note
Observe the following points to avoid malfunctions from electromagnetic inter­
ference:
Use a large-cross-section earth conductor that is as short as possible.
The earth conductor should ideally be a braided conductor, alternatively a
cable with a cross section of at least 2.5 mm², preferably 4 mm², and a maxim­
um length of 20 cm. A different cable may be required depending on the
installation situation.
Connect the earth terminal with low resistance and low impedance to the
earth potential.

8 Address assignment of the valves
Addresses are allocated in ascending order without gaps, from left to right. Depen­
ding on the integrated electrical interlinking module, a valve position occupies the
following number of addresses:
Electrical interlinking module Number of
valve positions Number of
occupied
addresses per
valve position

If one valve occupies both addresses of a valve position:
– Solenoid coil 14 occupies the less significant address.
– Solenoid coil 12 occupies the higher-value address.
Address assignment does not depend on it is equipped with blanking
plates or valve plates.
