Assembly
W
The S4 sliding switch is used to assign the valve groups (4 or
8 valves) (see "Selecting the valve supply" on page 67). This
enables e.g. a separate switch-off.
W
Both valve supply voltages (X10 pin 2, pin 4) must be
protected by an external fuse (3A, F).
The power supply cable must fulfill the following requirements:
W
Cable socket: 4-pin, A-coded without center hole
W
Cable cross-section: ≥0.5 mm

Dangerous voltages due to incorrect power pack
A power pack without safe isolation may lead to dangerous
voltages in the event of a malfunction. This may result in
injury from electric shocks or damage to the system.
O
Only use the following power supply for the bus coupler:
24 V DC PELV circuits in accordance with DIN EN 60204-
1/IEC 60204-1.
The PELV power source must be a safety isolation
transformer in accordance with IEC 61558-1 or
IEC 61558-2-6, or a power source offering the same
degree of safety as a safety isolation transformer.
Make sure that the power supply of the power pack is
always less than 300 V AC (outer cable – neutral wire).
