ETS-Lindgren 3725-2M LISN - Manual (Page 13)

4.0 Installation and Application
Before connecting any components, follow the
safety information in the ETS-Lindgren
Product Information Bulletin included with your
shipment.
Overcurrent protection is not provided in the
Model 3725/2M. The unit must be connected to
a power mains which has appropriately rated
mains protection installed.
Due to the high leakage current to ground
inherent in this type of equipment, it is
necessary to ground the Model 3725/2M to an
appropriate earthing point of the power mains
prior to applying power. This earthing point
should be determined by an electrician
authorized to do such work by appropriate code
or law. Any interruption of the protective
conductor inside or outside of the product is
likely to make the product dangerous.
Intentional interruption is prohibited.
The Model 3725/2M 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.
