CHAPTER 4
TROUBLESHOOTING
WARNING
Proper grounding is an important safety feature, and must be a primary consideration in all electrical and
electronic equipment installations. Ensure that all grounding connections are secure and that all grounding
cables are kept out of vehicle and personnel paths.
WARNING
Use extreme care when working around electrical equipment to avoid the possibility of severe or fatal
electrical shock. Remove all jewelry (i.e. rings, necklaces, etc.) before working with the Unit.
WARNING
Ensure that all power connections are properly insulated, clean, and mechanically secure to prevent
personnel injury when the Unit is powered up and operated. When the power cable is installed, carefully
inspect all connectors and wiring for worn or broken parts. Make any necessary repairs before powering up
the Unit. If any cable or connector damage is discovered while the Unit is operating, the Unit should be
powered down and the damage repaired immediately.
WARNING
Even with covers removed, lethal voltages may still be present inside the Unit. Failure to exercise caution
could result in fatal or serious injury to personnel.
WARNING
AC line voltage is present in this equipment. Use extreme caution and ensure that at least two people are
present while performing inspection, test, and maintenance procedures. Failure to comply may result in fatal
or serious injury to personnel.
WARNING
Ensure that power is removed during the performance of equipment replacement and cleaning procedures.
Do not open equipment enclosures when cleaning. Use of damp cleaning materials can cause shock,
resulting in fatal or serious injury to personnel.
