Electrical installation
See 9. “Wiring diagrams” on page 103.
Warning!
Risk involving electric current.
Only authorized and qualified electricians are permitted to install
the unit and open the housing. The unit may only be taken into
operation when the housing is closed, and must be connected to
protective earth. Modifications to the unit that go beyond those
described in this manual are not permissible.
Comply with local regulations when installing the unit (e. g. GUV).
Warning!
The unit is not equipped with a mains switch and is in operation as
soon as the supply voltage is applied. An external switch or circuit
breaker is therefore necessary.
Provide a mains fuse locally (6 A). The conductor cross section of
the mains cable must be at least 0.75 mm (AWG 18).
When connecting system components (e.g. devices, motors,
pumps) as well as when entering operating data, the system
components must be switched off in order to prevent uncontrolled
activation or any incorrect function.
Attention!
To ensure safe and correct commissioning, knowledge of the
operation, connected electrical load, measurement signals, cable
assignment and fuse protection of the connected devices and
machines and the relevant safety regulations is required.
Commissioning of the unit may therefore only be performed by
qualified and authorized electricians.
Incorrectly connected devices can be damaged, possibly
irreparably, or cause faults in other equipment when they are
switched on or in operation. Ensure that the measuring and control
cables are not mixed up or are able to make contact with one
another. Never connect or disconnect any cables to which voltage
is applied!
