Connection Method

Take care of wiring this power supply. Incorrect wiring will damage this product.

5. Block Diagram

· 

Be sure that all power lines are disconnected when wiring connections for input, output and connector 
terminals.

· 

Route input line and output line separately to avoid noise interference.

· 

Connect protective earth grounding to the          terminal of this power supply.

· 

Use the recommended connectors described in section “3-2. Appropriate Connectors. Housing and Terminal 
Pins for use in this power supply”.

· 

Connector accessories are not included in the delivery package.
