10. Maintenance
When maintenance is to be performed on the RCI-4100 system, care must be taken to ensure that the
level of safety is not reduced. Such a reduction in the level of safety can easily be done by the
careless use of tools or test equipment, either directly or by damage to safety components, wiring or
clearances. Therefore it is essential that maintenance be performed by competent personnel only.

procedures.
