Power Connection

When connected to a standard Ethernet connection, NG Series Industrial Wireless Gateways require an

external power supply connection using the supplied A-coded M12 field wireable connector or optional

M12 power cable accessory.

! WARNING

HAZARDOUS ENVIRONMENT

RISK OF EXPLOSIVE ATMOSPHERE.

The power over ethernet function may not be utilized in a hazardous

atmosphere. Only a suitable DC power supply may be utilized to power the

equipment in a hazardous area.

The power connection also serves as an optional secondary power supply connection when using a PoE

plant network connection. If needed, use the supplied A-coded M12 field wirable connector or optional

M12 power cable accessory to connect to an external power supply to establish a redundant power supply

connection.

The secondary supply allows for continued operation should the primary supply fail. Switching between

the primary and secondary supply will cause the gateway to reboot and results in temporary loss of

wireless connectivity.

The A-coded M12 connection uses these wiring connections:

The power cable and connector can be used as an alternative to the magnetic interface to reset the

gateway TCP/IP IPv4 address or restore the gateway to factory default settings.

Using an appropriate tool, the M12 power connector must be tightened to a torque of 0.6Nm.
