Replace the Lexan shield to the isolation panel
Verify that SW1 is set correctly (115V AC). At the end of the step, replace all Lexan shields and secure the compartment door after installing the isolation panel. Send the circuit board to the automation company for maintenance, or dispose of the old circuit board according to your company's procedures and local regulations! Note: SW1 must be set to the appropriate control power. Setting SW1 to the wrong setting will cause damage to the isolation panel and other components.
