3.4 Supply voltage
The reader has to supplied by a limited power supply (e.g. NEC Class 2/LPS power supply) ac-
cording IEC EN 60950, only.
The supply voltage of 24 V is connected to Terminal X6.
Vcc – supply voltage + 24 V

Note:
Reversing the supply voltage polarity may destroy the device.
To meet national requirements for radio frequency devices the power supply line must
be fitted with one of the supplied EMC ring cores 28 mm x 20 mm. The power supply
line must be wound around the ring core for at least 5 turns. The distance between the
Reader termination and the ring core should be maximum 10 cm.
