If the X1 terminals are already being used by the optional hard disk, the power supply must be connected in an Ex-certified terminal box outside of the HMI..
If there is no internal hard disk and other devices are to be supplied with 24 VDC, the optional X12 terminal block can be used to distribute the supply voltage.
24VDC at X12 terminal block:
HMI 24VDC power supply
ReaderBox X1
|
Because Ex-e and Ex-i signal circuits must not be connected at the same time, any free terminals may only have Ex-e signal circuits connected !

The data cable X2 is multi-core cables. Any unused wires are not assigned in the ReaderBox.
The unused wires of X2 must be isolated according to applicable regulations. This may be by means of double isolation and mechanical fixing by shrink sleeving or vulcanisation. The shrink sleeving or the vulcanisation must be suitable for at least 500 V and be within the temperature parameters of the device. The shrink sleeving / vulcanisation must not be light blue. When the data cables are shortened, this must also be kept in mind.
