4) After having completed the installation, make sure the wiring is correct.
5) Please install the leak current protective breaker at the output power
distribution panel of the UPS if necessary.
6) 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.
7) 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.
8) It is suggested to charge batteries for 8 hours before use. After connection,
turn the input breaker to the “ON” position, and then UPS will charge 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.
9) 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.
3.6 Operating procedure for connecting the long backup time
model UPS with the external battery
1) The nominal DC voltage of external battery pack is 240VDC. Each battery
pack consists of 20 pieces of 12V maintenance free batteries in series.
To achieve longer backup time, it is possible to connect multi-battery packs, but
the principle of “same voltage, same type” should be strictly followed.
2) The connector of the external battery cable is used to plug into the external
battery socket of the UPS, the other end of the external battery cable is connected
to the external battery pack(s). The procedure of installing battery bank should be
complied with strictly. Otherwise you may encounter the hazardous of electric
shock.
(1) A DC breaker must be connected between the battery pack and the UPS.
The capacity of breaker must be not less than the data specified in the general
specification.
(2) Set the battery pack breaker in “OFF” position and connect the 20 pieces
of batteries in series.
(3) You must connect the external battery cable to the battery first. If you
connect the cable to the UPS first, you may encounter the hazardous of electric
shock.
(4) Please prepare the external battery cable that should be able to carry the
current of >32A for 6KVA, and >50A for 10KVA, the cross section area should be
greater than 10mm²(6AWG) for all model. And battery wire color is recommended
as following:
(5)The positive pole of the battery is connected to the UPS in parallel with
red wires; the negative pole of the battery is connected to the UPS in parallel with
black wires; the green and yellow ribbon wire is connected to the ground of the
battery cabinet.
3) To complete the connection by plugging the connector of the external battery
cable into the external battery socket of the UPS. Do not attempt to connect any
loads to the UPS now. You should connect the input power wire to the right
position first, and then set the breaker of the battery pack in the “ON”position.
After that set the input breaker in the “ON”position, the UPS begins to charge the
battery packs at the time.
