MAINTENANCE
5.1 Introduction
This chapter contains preventive maintenance information for the DC Asterion Series
power supplies.
WARNING!
All maintenance that requires removal of the cover of the unit should only
be done by properly trained and qualified personnel. Hazardous voltages
exist inside the unit. Disconnect the supply from the AC mains input before
performing any maintenance. Service, fuse verification, and connecting of
wiring to the chassis must be accomplished at least 5 minutes after AC
input power has been removed with an external disconnect switch. Do not
touch any circuits and/or terminals that are energized.
5.2 Preventive Maintenance
WARNING!
The OFF position of the front panel power switch does not remove AC
input from internal circuits or input terminal blocks. Disconnect external
AC input before servicing unit.
CAUTION!
For safe and continued operation of the DC Asterion Series, always
operate the unit in a temperature and humidity controlled, indoor area.
Exposure to conductive contaminants or corrosive compounds/gases that
could be ingested into the chassis could result in internal damage. Keep
the rear and sides of the unit free of obstructions to ensure proper
ventilation.
No routine maintenance on the DC Asterion Series is required, aside from periodic
cleaning of the unit and inspection, as required by the environmental operating conditions:
