*1. Do not use an inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but
       the rise in the internal temperature of the Power Supply may result in ignition or burning.
*2. Refer to Data sheet for details on adjusting the output voltage for parallel operation. If set to less than −10%, the
       undervoltage detection function may operate. Ensure that the output capacity and output current after adjustment do
       not exceed the rated output capacity and rated output current respectively. Adjusting V.ADV may cause the output
       voltage to exceed the voltage range. When adjusting the output voltage, confirm the actual output voltage from the
       Power Supply and be sure that the load is not damaged.
*3. Class 2 approval does not apply to parallel operation.
*4. The output current is specified at power output terminals.
*5. Refer to the Engineering Data on Data sheet for details.
*6. To reset the protection, turn OFF the input power for one minute or longer and then turn it back again.
*7. Be sure to mount End Plates (PFP-M) on both ends of the Power Supply.
*8. The range for compliance with EC Directives and safety standards (UL, EN, etc.) is 100 to 240 VAC (85 to 264 VAC).
*9. The noise level depends on the wiring method and other factors. Insert one clamp filter (the ZCAT2436-1330A from
       TDK) as a noise countermeasure on the input line and ground line combined.
