For all standard model UPS, it is advised to charge the batteries over 8 hours
before using. Once the AC mains power energizes the UPS, it will automatically
charge the batteries. Without prior charging, UPS output remains as usual but with
shorter back-up time than normal.
When connected to motor, display equipment, laser printer etc, UPS power
selection should be based on the startup power of the load which is usually twice
as rated power.
Wiring by a qualified electrician is required. Ensure input cables and output cables
are connected correctly and firmly.
If install a leakage current protective switch, please install it on output cable.
For 1-3K series long backup model units, you may need to prepare wires for
terminals based on the following table.

3.3 Installation and output connection
Normally, output connection of 1~3kVA series is configured with power outlets or
terminal blocks, users can plug the load cable into the UPS power outlets to energize
the load. Make sure the mains cable and breakers in the building are enough for the
rated capacity of UPS to avoid the hazards of electric shock or fire.
3.4 External batteries connection (long backup model)
For different UPS model, users are instructed to configure different battery voltage
as below table. More or less units are forbidden, or else something abnormal or
faulty will appear.
