1: QP: Quasi-peak value, Mean : Average value
2: The MELSEC-ST series is an open type device (device incorporated in another device) and must be installed in a conductive control
panel.
The corresponding test is performed while the MELSEC-ST series is installed inside a control panel.
3: Use an external power supply introduced in Section 11.1.4. Mount the external power supply and MELSEC-ST series modules to the
same DIN rail.
Wiring connected between the following modules is treated as internal wiring and it is tested as an integrated system.
Between external SYS. power supply and bus refreshing module (ST1PSD)
Between external AUX. power supply and bus refreshing module (ST1PSD)
Between external AUX. power supply and power feeding module (ST1PDD)
