4. Maintenance
CAUTION:
Disconnect AC & DC power before performing any maintenance.
The unit is basically free from any maintenance except for keeping it clean and dirt-
free. If the unit is mounted in a dirty environment it may well be necessary to vacuum
it occasionally to keep it free from lint and dirt particles. The equipment is not
designed to be mounted in an area of highly corrosive fumes or conductive particles.
Conductive dirt particles in the atmosphere will definitely cause malfunction of the unit.
4.1 Adjustments
The equipment is properly adjusted and fully tested by the factory. However, if
any adjustments need to be made, it is probably due to component changes in
the field over a long period of time. Under those circumstances it is important
that the user contact the factory for further instructions. The attached table can
be used as a basic trouble shooting guide. It is important to note however that
this equipment is fairly sophisticated and service should not be attempted by
inexperienced personnel. It is important that accurate DC and AC meters be
available to properly measure DC operating battery voltage and AC input and
output voltage.
4.2 Troubleshooting
Table 4.1 presents a basic trouble shooting guide. Replacement of fuses must
only be accomplished after removing the input power to the unit and pressing
the battery OFF button.
