Groups of valves can be supplied with power via the U
The S4, S5, and S6 sliding switches are used to assign the valve groups
(4 or 8 valves) (see "Assigning the valve supply" on page 58). It is therefore
possible to switch off the valves before or after an emergency OFF.
The power supply cable must fulfill the following requirements:
Cable socket: 4-pin, A-coded without center hole
Cable cross section: > 0.5 mm
Length: Max. 20 m

A standard power pack can supply all system components with 24 V.
Dangerous voltages
A power pack without safe isolation may lead to dangerous voltages in the event
of a malfunction. Injuries from electric shock and system damage may be the
consequences.
Only use a power pack with safe isolation according to EN60747, VDE 0551
classification! The corresponding electrical circuits are thus SELV/PELV
circuits in accordance with IEC 60364-4-41.
To connect the bus coupler load supply:
1. Set up the correct pin assignment (see tab. 7 on page 53) on the plug connections
if you do not use pre-assembled cables.
2. Connect the bus coupler operating voltages using the socket coupling
(see "Spare parts and accessories" on page 75).
3. Check the operating voltage specifications using the electrical characteristics
and comply with them (see chapter "Technical Data" on page 74).
4. Provide power according to tab. 8, page 54. Select the cable cross-section
according to the cable length and occurring currents.
