1. Installation sequence is as follows:
1.1 First, determine the installation location of the UPS and battery cabinet upon arrival at the site.
1.2. Install the battery connection Wires.
A. Determine the location of the battery switch, the positive and negative directions of the batteries in the battery cabinet, and install the air switch and terminal connectors on the battery cabinet.
B. Connect the positive terminal of the battery to the air switch.
C. Wrap the battery cables from the next layer to the upper layer with tape to prevent accidental short circuits, and ensure the bolts are securely tightened.
D. Clearly distinguish the final exposed positive and negative terminals to prevent incorrect connections; the positive terminal connects from the air switch to the terminal block, and the negative terminal connects directly from the battery's negative terminal to the terminal block.
E. Ensure there are no unrelated items in the battery cabinet.
F. Before connecting the battery cables from the battery cabinet to the host, measure the battery voltage with a multimeter, which should be 103.36V, and check if the positive and negative leads are correctly connected.
If there is a battery box, connect the batteries in series and link them to the host as required.

2. UPS Battery Wiring Example
A. For a 10KW UPS, 6-square copper wires are recommended; for those below 10KW, 4-square copper wires are preferable.
B. The most important aspect of installing a UPS power supply is connecting the batteries. The key to connecting the batteries is to link the positive terminal to the negative terminal, connecting each battery in series, and then leading out two power cables, one positive and one negative, to connect to the air switch.
C. The battery power cables can be made into a plug to connect to the UPS host, which can also have other sockets made on it.
D. The host input will have two forms: one is city power input, and the other is battery input. City power input involves connecting to a 220V or 380V power source, with the live wire connected to L and the neutral wire connected to N.
E. Battery input to the host involves connecting positive to positive and negative to negative. Be sure not to reverse the connections.
F. The output terminal is where the device's power can be connected, which is the final power source we need. The host automatically stabilizes the voltage, preventing voltage surges that could damage the equipment.
