INSTALLATION
The CAMUTP24 must be properly installed to insure maximum protec-
tion. The function of the CAMUTP24 is to allow a surge to be routed to ground
and to clamp the protected equipment inputs to a minimum voltage.
There are three key points to remember when installing the CAMUTP24.
First provide a low impedance connection between the CAMUTP24 and your
protected equipment. This is best done by keeping the PROTECTED cable
connections as short as possible.
Second the system should use a single ground point. Connect the
grounding stud of the CAMUTP24 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 ground. If
the CAMUTP24 and the protected equipment are both grounded you will provide
a parallel path to ground and a portion of the surge current can flow though that
path.
Finally, the UNPROTECTED cables should not be crossed with the
PROTECTED cables. Crossing cables could provide a path for surge currents
to bypass the CAMUTP24 protection circuits.
