Installing the ERU
Electrical code compliance
The ERU must be grounded in accordance with Section 810 of the National
Electrical Code (NEC), Section 10 of the Canadian Electrical Code (CEC), or
the electrical code of the country in which you are installing the ERU. The
following illustration, which is not to scale, depicts the grounding requirements.
Grounding options A to C are described on page 48.

CAUTION:
It is extremely important to ground the ERU and the coaxial
cable to a single point in the central building ground. A nearby lightning strike can
easily damage the ERU, the SOMAport, and any attached equipment. Connecting
both wires to the same point in the central building ground meets code
requirements and provides the best protection for your equipment.
