3.3 Power source

The Atlas-840 router is powered through one or two internal AC/DC sources, depending on the model. The Atlas-

a backup.
There is no on/off switch or fuse. The power supply information is printed on the rear side of the device.
Warning
Safety regulations require that the location where the equipment is installed must incorporate a discon-

less than 10 A.
To avoid electric shocks, residual current circulation, and other unwanted effects that also affect communications, the

provided), and connect it to the grounding point on the rear panel of the Atlas-840
using a 3.5 mm screw and washer. Then connect the other end of the wire to the
