6. Power supply
Access point power supply connector contains power supply inputs and two
digital inputs / outputs. Voltage level of power supply and digital inputs / outputs
corresponds with power supply voltage 24 V DC.

Connection to chassis
Access point can be powered only by DC power supply with nominal voltage.
Power supply voltage is connected to power supply terminals Vcc and GND of
X1 connector. Terminal SB is used for turning access point on and off, terminal
PE is used for connection to chassis.
Power supply (terminals Vcc, GND and SB) is galvanically separated from
internal electronics. Galvanic separation must not be used for dangerous
voltages separation.
When installing, it is recommended to connect the PE terminal in single point of
switchboard with chassis of equipment where the access point is installed.
The power supply conductors cross-section must be at least 0.75 mm

GND / not connected Device is OFF
After disconnecting the SB pin from supply voltage is launched the procedure
for system switching off. Access point is switched off immediately after
completion of operating system run
– it takes no more than 1 minute.
The PE terminal is internally connected with access point casing and with metal
caps of all connectors.
