Safety Considerations
Preventive Maintenance
Note: Preventive maintenance is limited to cleaning the unit and connectors.
Cleaning
Front Panel
Clean the front panel face and meters with a soft cloth dampened with a mild detergent solution. Do not use an
excessive amount of water that would enter the unit and damage electrical components.
Line Section
Clean the line section connectors and elements with a dry cleaning solvent. Use a clean cloth to clean the mating
surfaces of the larger line sections and a cotton swab stick for the smaller connectors, elements, and line section ele-
ment socket. Clean all mating surfaces thoroughly, especially the bottom shoulder of the element socket and the
spring contact finger.
WARNING
Become thoroughly familiar with modern methods of resuscitation before working
near high voltage sources.
WARNING
Shock hazard. Always turn off AC power before removing any equipment panels.
WARNING
Disconnect this unit from AC power source before any disassembly for cleaning, repair
or replacement procedures. The potential for electrical shock exists.
WARNING
When using dry cleaning solvents, provide adequate ventilation and observe normal
safety precautions. Many dry cleaning agents emit toxic fumes that may be harmful to
your health if inhaled.
CAUTION
Do not bend this contact finger when cleaning. The position of this contact is some what
critical. If it is out too far the element will not enter the socket and if it is in too far, it will not
make contact with the button on the element. For contact adjustments, refer to "Adjusting
the Element Wiper Contact" on page 18.
