ETS-Lindgren 4825-2 LISN - Manual (Page 14)

The Model 4825/2 is provided with resistors to
help bleed off high voltage transients, but it is
advisable to connect the input and output
connectors to their proper power lines and
loads before connecting the monitor port to the
measurement instrumentation; otherwise,
power surges or transients can damage the test
instrumentation mixers or attenuators.
The Model 4825/2 Line Impedance Stabilization Network (LISN) is designed for
use in Installation Category II and Pollution Degree II per lEC-1010 and IEC-664.
When installing in a cabinet, make sure that the convection around the product is
not restricted. The ambient temperature outside the cabinet must be less than
the maximum operating temperature of the Model 4825/2 by 4 ° C for every
100 watts dissipated in the cabinet. If the total power dissipated in the cabinet is
greater than 800 watts, then forced convection must be used.
