4.0 Installation
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 3850/2. The unit must be connected to a
power mains with properly rated mains
protection.
The Model 3850/2 is provided with a protective
earthing connection. The unit should only be
connected to a mains source which utilizes a
protective earth conductor. Due to the high
leakage current to ground inherent in this type
of equipment, it is necessary to properly
connect the Model 3850/2 to an appropriate
earthing point on the power mains prior to
energizing. This earthing point should be
determined by an electrician authorized to
perform such work by appropriate code or law.
Any interruption of the protective conductor
inside or outside of the unit is likely to make the
Model 3850/2 dangerous. Intentional
interruption is prohibited.
The Model 3850/2 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.
