Periodic Maintenance
For standard models (without air filter), NO routine maintenance of the power supply is required
except for periodic cleaning.
To clean the device:

The solution should be applied onto a soft cloth, and not directly to the surface of the unit.
CAUTION
Do not use aromatic hydrocarbons or chlorinated solvents for cleaning. Use low pressure
compressed air to blow dust from the unit.
3. For units with optional air filter assembled, refer to Air Filter Kit Manual for maintenance
instructions.

cover.
Cover removal is allowed only by TDK-Lambda qualified service personnel.
