Overview

The CAMPPTR1 must be properly installed to ensure maximum protection. The function of the CAMPTR1 is to allow a surge to be routed and to clamp the protected equipment inputs to a minimum voltage. There are three points to remember when installing.

First, provide a low impedance connection between the CAMPTR1 and protected equipment This is best done by keeping the PROTECTED Connection as short as possible.

Second, the system should use a single ground point. Connect the grounding wire of the CAMPTR1 to a single ground point. A single ground point is a proper building ground or earth ground to which equipment grounds are connected. Ideally, the protected equipment should be isolated from the ground. If the CAMPTR1 and the protected equipment are both grounded you will provide a parallel path to the ground and a portion of the surge current can flow through that path.

Finally, the UNPROTECTED cable should not be crossed with the PROTECTED cable. Crossing cables could provide a path for surge currents to bypass the CAMPTR1 protection circuits.
