6-14. TEST PRECAUTIONS AND NOTES
Connect the test setups only when directed and with the power supply turned off. The large
current capacity of the test power supply can cause personal injury. Verify the test setup
before turning the power supply on.
High voltage is present in the test adapter (115 V ac). Use caution when troubleshooting to
avoid personal injury.
Static electricity and stray voltages can damage the rt modules. Use an antistatic pad on
the work surface and wear a grounded wrist strap when removing or installing the rt front
The principles of operation section, functional block diagrams, and the test adapter sche-
matic in FO-16 can be used to fault isolate any unusual problems that may not be covered in
the troubleshooting procedures.
If a problem cannot be found in the test adapter, check the test cables using the schematics
in figure 65 and the DMM.
