1-8. Replacement of AC.DC/DC Convertor
CAUTIONS To avoid electric hazards, the power to the unit should be turned off during replacement. Before beginning replacement, be sure not only to turn off the power switch but to disconnect the cables from the TRIAX or DC IN connector. The power block will go very hot during operation. If you remove the side panel and touch the power block, there is some danger to get burned. When you open the side panel for replacement, please allow for at least 10 minutes after powering off until the inside cools off. n Every electrical part used in the AC.DC/DC convertor cannot be replaced. If there is any defective part, replace the convertor block itself.

3. Remove the three screws and pull out the AC.DC/DC convertor. 4. Disconnect the three connectors.
