●
Do not short the positive and negative of battery electrode. Otherwise, it may cause electric shock or fire.
●
To avoid the risk of being shocked, please do not attempt to open the case of the UPS.
●
A battery can present a risk of electric shock and high short circuit current.
●
Do not plug household appliance such as hair dryers to UPS.
3. Installation
3.1 Unpacking and inspection
1) Unpack the packaging and check the package contents. The shipping package contains:
●
A UPS
●
A user manual
●
A communication cable
2) Inspect the appearance of the UPS to see if there is any damage during transportation. Do not turn on the unit and notify the carrier and
dealer immediately if there is any damage or lacking of some parts.
3.2 Input and output power wiring and protective earth ground installation
3.2.1 Notes for installation
1) The UPS must be installed in a location with good ventilation, far away from water, inflammable gas and corrosive agents.
2) The UPS should not be tilted. The air inlet port at the lower part of the front panel and the fan outlet port on the rear panel should not be
blocked so as to ensure good ventilation (Allow at least 0.5m of space on each side).
3) In case if the UPS is unpacked, installed and used at very low temperatures, condensation of water drops may appear. It is necessary to
wait until the UPS is fully dried inside out before proceeding to installation and use. Otherwise, there may be a risk of electric shock.
3.2.2 Installation
Installation and wiring must be performed in accordance with the local electric code and the following instructions by professional personnel.
For safety, please cut off the mains power breaker before installation. The battery breaker also needs to be cut off if it is a long backup time
model.
1) Open the terminal block cover located on the rear panel of the UPS (please refer to the appearance diagram).
2) For 6KVA UPS, it is recommended to select the UL1015 10AWG (6mm
2
) wire or other insulated wire which complies with AWG Standard for
the UPS input and output wirings.
3) For 10KVA UPS, it is recommended to select the UL1015 8AWG (10 mm
2
) wire or other insulated wire which complies with AWG Standard
for the UPS input and output wirings.
Note: Do not use the wall receptacle as the input power source for the UPS, as its rated current is less than the UPS’s maximum input current.
Otherwise the receptacle may be burned and destroyed. (Please refer to section 1.4)
4) Connect the input and output wires to the corresponding input and output terminals according to the following diagram.
Note: You must make sure that the input and output wires and the input and output terminals are connected tightly.
5) The protective earth ground wire refers to the wire connection between the equipment which consumes electro-equipment and the
ground wire. The wire diameter of protective earth ground wire should be at least as above mentioned for each model and green wire or
green wire with yellow ribbon wire is used.
6) After having completed the installation, make sure the wiring is correct.
7) Please install the leak current protective breaker at the output power distribution panel of the UPS if necessary.
8) To connect the load with the UPS, please turn off all the loads first, then perform the connection and finally turn on the loads one by one.
9) No matter the UPS is connected to the utility power or not, the output of the UPS may have electricity. The parts inside the unit may still
have hazardous voltage after turning off the UPS. To make the UPS have no output, power off the UPS, and then disconnect the utility
power supply.
10) Suggest charging the batteries for 8 hours before use. After connection, turn the input breaker in the “ON” position, the UPS will charge
the batteries automatically. You can also use the UPS immediately without charging the batteries first, but the backup time may be less
than the standard value.
11) If it is necessary to connect the inductance load such as a monitor or a laser printer to the UPS, the start-up power should be used for
calculating the capacity of the UPS, as its start-up power consumption is too big when it is started.
