3.2.1 Supply voltage
The reader ID ISC.M02.M8-B has to supplied by a limited power supply (e.g. NEC Class 2/LPS
power supply) according IEC EN 60950, only.
If switching power supplies are used with the module, be sure that there is adequate filtering.
Noise from the power supply can result in a reduction of the read/write range of the module.
The cable length from the power supply should be as short as possible, and should in any case not
exceed 1 m.
Note:

A wrong polarity of the DC voltage will destroy the reader

Supply voltages outside the specifications may destroy the device.
