2.4 Product installation instructions
2.4.1 Installation attentions
1. Put UPS in a well-ventilated place and ensure the heat emission holes and fan
peripherals of the chassis meet the ventilation conditions at a distance of
150mm above and keep away from water, combustible gases and corrosives.
2. Turn off the devices which need uninterrupted power supply (such as host
computer), disconnect the power cord from the utility power socket and connect
it to the output socket of UPS connect the devices which do not need to be
connected with UPS to the common utility power socket.
3. Put UPS input plug into the utility power socket (ensure the zero wire and live
wire are correct and the ground wire is good).
4. The ambient temperature of UPS shall be kept between 0
℃
and 40
℃
.

Warning:
In order to ensure the safety of equipment and personnel, theinstallation must be
carried out by professionals.
1. First connect the battery bank with accompanied battery connecting wires (note
the red wire shall be connected to the anode, and the black wire shall be
connected to the cathode).
2. Confirm the connection of the battery bank. Measure the identification of the
battery input socket and the positive and negative of battery wire terminals of
UPS with a multimeter. The voltage shall be consistent with UPS’s input DC
voltage.
3. Be sure to check whether the installation is correct or not after it is completed.
