12.3 How to Turn ON/OFF Whole System

A switching system, once put into service, is seldom stopped. However, there may be a case when a switching system must be stopped due to module expansion work, etc. In preparation for such a case, this section explains the procedure for stopping the system and turning ON the power supply.
