6 Connecting the system power supply
The Touch Operator Panel is classified to protection class 3. The system power supply must be connected to
an SELV (safety extra-low voltage) 24 V DC supply (see Section 17). The power supply is not isolated. The
0 V terminal is located directly on the housing potential. The power supply must be fuse protected
(2.5 A slow), (see Section 17). This can be accessed without having to open the device. The unit is protected
against reverse polarity, and the operation of the unit depends on correct polarity.
Observe the relevant regulations for the connection of the units.
Carry out the connection as follows:
– The cross-section of the supply cable must be between 0.75 mm² and 2.5 mm² .
– A lead or wire can be used for the connection.
– The power supply must be provided with the correct current rating (see Section 17), selectivity and
breaking capacity in accordance with the specified disconnection characteristics (see Section 17).
– A functional ground is not compulsory for correct operation. The GND is connected directly to the housing
potential.
The connector (socket strip with screw terminals) is supplied with the device.
