*1 When applying for safety standards are 100 to 240 VAC, 50/60 Hz.
*2 The rated input voltage and rated frequency when applying for safety standards are 100 to 240 VAC, 50/60 Hz.
*3 To return, turn OFF the input power supply and after leaving it off for 1 minute or more, plug in the input power supply again. The E/F Series is a Zener diode clamp type. It will not restart after the protection circuit operation.
*4 For the MS2-H100, this is applicable only when the load ratio is 70% or lower.
*5 The applicable standards do not apply for parallel and serial operations.
