7-2 Maintenance OT01-PCR-LA/2
7.1 Maintenance
• There is a possibility of electric shock, which could result in physical injury
or death. Always turn OFF the POWER switch, then turn OFF the switch
on the switchboard.
7.1.1 Cleaning the Panel Surface
If the panel becomes soiled, wet a piece of soft cloth with a water-diluted neutral
detergent, and wipe the panel gently.
• Do not use volatile solvents such as thinner or benzine, as they may dis-
color the unit surface coating, erase printed characters, or make the face
of the display unit opaque.
7.1.2 Cleaning the Air-intake Filters in the PCR-LA Power
Supplies
The inside of the louver on the front panel of a PCR-LA power supply is equipped
with air-intake
fi lters. Clean these fi lters periodically before they become extremely
clogged. For more information on the cleaning procedure, see the PCR-LA AC
Power Supply Operation Manual.
• If an air-intake fi lter becomes clogged, the internal cooling effects of a
PCR-LA power supply are degraded, which may cause a problem or
shorten the life of the power supply.
7.1.3 Inspecting the Power Connection Cables
Check the power connection cables for external damage. In addition, check to con-
fi rm that no connection terminal screw has become loose.
