W
Observe the safety notes found in the operating instructions
of the complete valve system.
W
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).
W
Switch off the operating voltage before connecting or
disconnecting plugs.
W
The warranty only applies to the delivered configuration.
The warranty will not apply if the system is incorrectly
assembled.
W
Make sure the relevant system component is not under
pressure or connected to voltage on assembly or
disassembly. Ensure that the system is protected from
reconnection during assembly work.
W
Connect the modules and the valve system to functional
earth (FE):
– Connection according to DIN EN 60204-1/IEC 60204-1
W
Installation may only be performed in a voltage-free and
pressure-free state and only by a qualified technician. In
order to avoid accidents caused by dangerous movements
of the actuators, electrical commissioning is to be carried
out only in a pressure-free state.
W
Do not put the system into operation before it is completely
assembled as well as correctly wired and configured, and
after it has been tested.
W
The device is subject to the restrictions of the IP69K
protection class. Before commissioning, make sure that all
the connection seals and plugs are leak-tight to prevent
fluids and foreign particles from penetrating the device.
