batteries), 96VDC for 2KS/ 3KS (8 pcs of 12V batteries).

cord of the UPS to supply utility power to the UPS to make the
UPS operate in utility power mode.
(4) Connect the plug of the external battery cord to the external
battery socket on the rear panel of the UPS to complete the
connection procedure and the UPS will start to charge the battery
pack.
(5) The red wire is connected to the "+" terminal of the battery. The
black wire is connected to the "-" terminal of the battery. (Note: the
green/yellow wire is grounded for protection purpose.)
The Caution!
The output sockets of the UPS system may still be electrically live
even if the power supply system has been disconnected or the
Bypass switch is on “OFF” position.
