Note:
1. Parallel operation should be composed with the same products, while the connection sho-
uld be as shown as “Parallel operation C;
2. In parallel operation C, current capacity cannot be increased, while it should be used for
backup only. Moreover, diode that is to be added during parallel operation should be selected
after considering it’s voltage drop, output voltage and current capacity.
