CAUTION
The 17” CRT monitor weighs 42 pounds. One person alone should not attempt the cabinet preparation and system installation. Obtain assistance. Failure to comply could result
in personal injury and/or equipment damage.
Cabinet preparation
1. Note the location at the top of the cabinet where the rack mount kit will be installed.
2. Mark the location in the cabinet.
System installation
Refer to Figure 1.
1. Assemble the two sides of the rack mount frame to the base with the screws supplied.
2. Assemble the front panel to the sides and base using the screws supplied.
3. Insert the left and right handles through the front of the rack kit and secure to the sides of the rack kit with supplied
screws.
4. Install the cage nuts into the four marked locations on the cabinet.
5. Install the assembled rack mount frame into the cabinet and secure with the four M6 screws supplied.
6. At the rear of the cabinet, slide the monitor into the rack mount frame as far to the front as it will go.
7. Using one of the supplied support bars with clamps installed, place it under the front of the monitor and lift the monitor screen to position it as parallel to the glass front of the rack mount frame as possible. Adjust the support bar
clamps as required to hold the monitor, then tighten in place. Secure the bar using the supplied screws and washers.
Use another support bar with clamps to raise and secure the rear of the monitor.
8. The top and rear support bars can now be installed to completely secure the monitor.
WARNING
The Model 4200-SCS must be separately connected to a safety earth ground to maintain
protection against possible shock hazard. Failure to connect the unit to a safety earth
ground may result in personal injury or death due to an electric shock.

Operation
Exercise extreme caution when a shock hazard may be present. Lethal voltage may be present on cable connector jacks or test
fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than
30V RMS, 42.4V peak, or 60VDC are present.
unknown circuit before measuring
For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the circuit under
test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or disconnecting cables or jumpers, installing or removing switching cards, or making internal changes, such as installing or removing jumpers.
Do not touch any object that could provide a current path to either the common side of the circuit under test or to the power line
(earth) ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding
the voltage being measured.

A good safety practice is to expect that hazardous voltage is present in any

Do not exceed the maximum signal levels of the instruments and accessories, as defined in the specifications and operating information, and as shown on the instrument or test fixture panels, or switching card.
Chassis connections must only be used as shield connections for measuring circuits, NOT as safety earth ground connections.
If using a test fixture, keep the lid closed while power is applied to the device under test. Safe operation requires the use of a lid
interlock.
Instrumentation and accessories shall not be connected to humans.
Maintenance and service
Inspect the connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before each use. Before performing
any maintenance, disconnect the line cord and all test cables.
Cleaning
Keep the connections free of contaminants (such as dirt, oil, etc.) in order to maintain maximum insulation resistance. If the
connections become contaminated, clean them thoroughly with methanol and allow them to dry completely before use.
