3.0 Installation
3.1 Unpacking and inspection
1. Unpack the UPS and check that it has not been damaged during transportation. If damage has
occurred or parts are missing, inform Secure Power Ltd immediately.
2. Check the annex (please consult Appendix Table 1).
3.2 Notes
1. Place the UPS in a clean, well ventilated and stable environment. Avoid locations with vibration,
dust, humidity and keep away from flammable gas, liquid and corrosive elements.
2. The ambient temperature around UPS should be in the range of 0℃～40℃. If UPS operates above
40℃, it is required that the rated value of the largest load decreases by 12％while the temperature
increases every 5℃. The operating temperature must not exceed 50℃.
3.3 UPS input connection
Connect the UPS to the mains by input power cable which is equipped with the UPS.

Warning:
►Before installing the battery, make sure that UPS and breaker are turned off. Remove all any
metallic objects such as rings, watches and so on before connecting.
►No anti-connection or short circuit between the battery anode and cathode forever. Red cable
connect with battery anode “+” and black cable connect with cathode “-”.
►Use a screwdriver with insulating handle and DO NOT lay the tools or metallic goods on the battery.
Notice:
►When using an external battery, it is best to use external battery cable which matches the
equipment.
►When connecting the load to the UPS, first turn off load and then connect the power cable, then
turn on loads one-by-one.
►Inductance loads such as motor, fluorescent lamps and photocopiers should not be connected to
the UPS, as damage may occur.
►Plug UPS into a socket with over-current protection, connected with a ground wire.
►The UPS is likely to have output voltage no matter whether the power input cable is plugged into
the mains input socket. If you wish the UPS to have no output, first break off the switch and then
cancel the mains.
►When connect to a laser printer, select the capacity of UPS according to the UPS start power
because the start up power is higher.

4.1.2 The function of LED indicators
Warning red LED is on: UPS is fault. For example: Overload beyond the allowed time, inverter fault,
BUS fault, over temperature fault etc.
Bypass yellow LED is on: UPS is alarming. For example: Bypass mode supply power and etc.
Battery yellow LED is on: UPS is alarming. For example: Battery mode supply power and etc.
Inverter green LED is on: UPS is normally powered by mains or ECO mode or battery mode.
After starting the UPS, the four LED’s will light and go out one-by-one. It circulates several times until
starting the UPS is successful.
NOTE: As to the LED indication in different modes, please refer to the LED display panel and warning
table.
