Maintenance | 9
2.0 Maintenance
Before Servicing contact ETS-Lindgren.
Servicing (or modifying) the unit yourself
may void your warranty. If you attempt to
service the unit yourself, disconnect all
electrical power before starting. There are
voltages at many points in the instrument
which could, if contacted, cause personal
injury. Only trained service personnel
should perform adjustments and/or
service procedures upon this instrument.
Before performing any maintenance,
follow the safety information in the
ETS-Lindgren Product Information
Bulletin included with your shipment.
Inside the Model 3810/2 are LETHAL
voltages with which you could come into
contact. Capacitors inside the unit may
still be CHARGED even when the unit is
disconnected from power.
Only trained service personnel should
perform adjustments and/or service
procedures.
WARRANTY

10 | Maintenance
For the steps to return a system or system component to ETS-Lindgren for
service, see the Product Information Bulletin included with your shipment.
Clean the exterior of the cabinet using a
damp cloth and mild cleaner. Always
unplug the unit before cleaning.
Maintenance of the Model 3810/2 is
limited to external components such as
cables or connectors.
If you have any questions concerning
maintenance, contact ETS-Lindgren
Customer Service.
To prevent electrical shock, do not
remove cover.

Installation and Application | 13
4.0 Installation and Application
The Model 3810/2 is provided with a protective
earthing ground integral to the power cord. The
mains plug should only be connected to an
outlet which incorporates a protective earth
contact. Due to the high leakage current to
ground inherent in this type of equipment, it is
necessary to install a supplemental protective
earthing wire from the protective earth terminal
on the rear panel to an appropriate earthing
point on the power mains. 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 3810/2 dangerous.
Intentional interruption is prohibited. The
supplemental ground wire is supplied with the
unit.
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 3810/2. The unit must be connected to a
power mains which has appropriately rated
mains protection installed.

14 | Installation and Application
The Model 3810/2 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 3810/2 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.
The Model 3810/2 is nominally designed for a 10 ampere current capacity.
Maximum line-to-line voltage must not exceed the voltage rating of the power
outlet provided on the front panel. See Specifications on page
The Model 3810/2 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.
11 for the
applicable maximum value.

Installation and Application | 15
The Model 3810/2 is provided with an RF bonding stud on both the front and rear
panels. The unit should be bonded to a ground plane in normal operation.
Connect the Model 3810/2 to the spectrum analyzer or EMI receiver through the
BNC connector.
Select the line to be monitored by the two-position selector switch. The line not
selected is internally terminated into 50 ohms. Switching between the two lines
will not generate transients.
Remove the BNC connection before disconnecting power.

EARTH LINE CHOKE SWITCH
The safety ground isolation choke selector switch switches the 1.6 mH earth line
choke IN and OUT of the safety ground circuit. The ground choke is designed
and manufactured with sufficient capacity to conduct the maximum current rating
of the Model 3810/2 and at no time is the safety ground of the unit compromised.
The earth line choke avoids a double RF ground connection (safety ground and
measurement ground) in the conducted emissions test setup.
AC RECEPTACLE
Connect the Equipment Under Test (EUT) to the panel-mounted AC receptacle.
The style of receptacle is determined by the model specified. Following are the
standard output receptacle types:
•NEMA (Type 5-15R)
•Schuko (Type CEE 7/7)
•British Standard (BS 1363)
•Australian (AS 3112)
ARTIFICIAL HAND
In conformance with EN55014 and BS800, the artificial hand connection is used
to test handheld equipment that is provided without earth connections.

Installation and Application | 17
The input power connection is made through the IEC-320 type power inlet. This
three-wire input power connector is rated at 10 amperes maximum. In case of
emergency, power can be removed from the unit by removing the power
connection at the Model 3810/2 input. Alternately, a properly rated circuit breaker
or switch which removes mains power from the unit can be installed in proximity
to the unit.

5.0 Data
Graphs of the calibration data for each measurement port of the Model 3810/2
Line Impedance Stabilization Network (LISN) are included with the unit. The
graphs provide individual plots of both impedance and insertion loss data.
Impedance is plotted in a semi-log format where frequency is displayed on the
horizontal from 9 kHz to 30 MHz. The vertical has a range of 0 ohms to
100 ohms and represents the measured impedance of the unit. The insertion loss
is also plotted with frequency on the horizontal from 9 kHz to 30 MHz. The
vertical of the graph has a range of -9 dB to 1 dB and represents the measured
insertion loss of the Model 3810/2.
ACertificate of Calibration Conformance is provided with each Model 3810/2.
