4. 0 Important Safety Precautions
The LISN must be securely fastened to the earth ground before making any connections to
external power
.
Proper grounding of the LISN not only ensures correct conducted emissions
measurements,
it also prevents potential high leakage current from presenting a hazard to test
personnel. To help establish proper grounding the bottom surface of the LISN is unpainted. In
addition, the bottom plate has holes for securely bolting the LISN to the ground plane.
Only connect power plugs with a protective earth contact into LISN power input port / AE. The
protective action must not be negated by the use of a cheater plug or an extension cord without
a protective conductor.
Caution
The LI-1100 LISNs uses forced air system to keep the air core inductors cool during the test.
Always use the supplied DC adapter to power the internal fan during the test. Do not obstruct
the airflow vents. Use the LISNs in a ventilated area. Failure to observe these precautions may
damage the LISN. Overheated LISN may also provide incorrect measurement data. In addition
the heat may start a fire or injure test personnel. If the fan stops working discontinue using the
LISN and contact Com-Power for further assistance.
