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 M1/M2/N input breaker (for tower 3/1
10k-20K), turn the input switch (for tower 3/1 10K-31C model) 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.

Important notes:
If the UPS is used in single mode, JP1 and JP2 must
be connected. If the UPS is used in parallel mode, the Jumper between
JP1 and JP2 must be removed.
