NOTE:
The following procedure must be carried out when the UPS is connected to the
generator:
■
First switch on the generator after it is running stably, connect the output power of the
generator to the UPS input terminal, and then switch on the UPS. After switching on the
UPS, please connect the load one by one.
■
It is recommended that the generator power is twice the rated power of the UPS.
