Caution: Before services gateway installation begins, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the services gateway.

Warning: The services gateway is a pluggable type A equipment installed in restricted access location. It has a separate protective earthing terminal [Metric -M6 and English - ¼-20 screw) ground lugs] provided on the chassis. This separate protective earth terminal must be permanently connected to earth.
