Power Supply Characteristics - SMA /SLA
Use an AC/DC power supply LPS type, Limited Power Source (as per IEC EN 60950-1 Ed2) or ES1 type, PS1 (as per IEC EN 62368-1) for main supply and for
an eventual V+/V-.

Recommendations - SMA / SLA
▪ Install the module/reader away from computer transmission cables or from power sources (ex: RJ45, sector…).
The disruptions that they can cause can vary according to their radiation power and their proximity.
▪ Use a filtered and regulated power supply.
▪ Antennas connected to different modules/readers may interfere with each other. Move them away from each other.
▪ A power supply which provides 1.5 A min under +12Vdc is recommended.
If the IN/OUT are powered by the module, use a 2A min under +12Vdc power supply.
▪ Users must not remain within a range of less than, 34 cm / 13.39 in from an antenna for an extended period of time as per EN50364 applicable to this
type of device.
▪ Apart from the hatch the module housings must not be opened.
▪ Before any service operation you must de-energize reader.
▪ Check that the hatch seal is correctly positioned before closing.
▪ Do not remove the caps of unused
cable glands:
▪ Do not remove the caps from the unused
RF connectors:
▪ Install the module/reader with the word UP
facing upwards so that the connectors are down:
Host Connection Access - SMA / SLA
In order to access the module/reader connectors, open only the hatch provided for this purpose by unscrewing the 4 captive screws without removing them from
the hatch.
