Device chassis
Router 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 router 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 isolation must not be used for dangerous voltages
isolation.
When installing, it is recommended to connect the PE terminal in single point of
switchboard with chassis of equipment where the router is installed.
The power supply conductor
’s cross-section must be at least 0.75 mm

After disconnecting the SB pin from supply voltage is launched the procedure
for system switching off. Router is switched off immediately after completion of
operating system run
– it takes no more than 1 minute.
The PE terminal is internally connected with router casing and with metal caps
of all connectors.
