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 Asterion DC Multioutput ASA
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 Asterion DC Multioutput ASA Series is required, aside
from periodic cleaning of the unit and inspection, as required by the environmental
operating conditions:
•
Once a unit is removed from service, vacuum all air vents, including the front panel
grill.
