NOTE:
The reader has to supplied by a limited power supply (e.g. NEC Class 2/LPS power sup-
ply) according EN 62368-1 chapter Q.1, only
Use only regulated power supply’s.
The connection cable (VCC; IN1/2) should be as short as possible and must not exceed
3 m to reduce the influence of noise.
Connection cables >0,5 m should be twisted paired and shielded.
Hf-connection cables (U.FL) >0,5 m should be wrapped around the connection cable to
avoid ground loops.
Reversing the polarity of the supply voltage may destroy the device.
Supply voltages outside the specifications may destroy the device.
If switching power supplies are used with the module, be sure that there is adequate fil-
tering.
Noise from the power supply can result in a reduction of the read/write range of the
module.
