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
following is recommended:
M20 Edge Router
Ensure the rack on which the M20 is to be mounted is properly grounded in com-
pliance with ETSI ETS 300 253. Verify that there is a good electrical connection to
the grounding point on the rack (no paint or isolation surface treatment).
Attach an eye ring (not provided) to a #18 AWG minimum grounding wire (not
provided), and connect it to the grounding point on the rear panel of the M20 using
a 3.5 mm screw and washer. Then connect the other end of the wire to the rack
ground.
