5) The protective earth ground wire refers to the wire connection between the equipment which
consumes electric equipment and the ground wire. The wire diameterof protective earth ground
wire should be at least as above mentioned for each model and green wire or green wire with
yellow ribbonwire 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 distributionpanelof 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 havehazardous voltage after turning off the UPS.
To make the UPS have nooutput, 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
inputbre
aker 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, JPI and JP2 must be connected
by 10AWG(6mm2). If the UPS is used in parallel mode, the Jumper between JP1 and
JP2 mustbe removed .
3.5 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 theprinciple of “same voltage, same type”
