Connect the cable B(1 cable)between different floors and bound one end of the cable with insulation tape，the other end of the cable should be connected to negative pole of the battery at the rear part of the floor;
e.When selecting the temperature compensation function, fix the temperature sensor TMP12Z(one of the accessories of battery cabinet) on the board where the battery circuit breaker is installed, bound the signal cables and lead the cables to the place where the wiring is convenient;
f.Place the 8 batteries on the second floor, connect the connection cables D (7 cables) between the batteries. The connection cables of the first floor will be connected to the positive pole of the first battery in the left side of second floor. One end of the connection cable B(1 cable) is bound with insulation tape, the other end is connected to the negative pole of the battery in the left rear part;
g.The wiring and layout of batteries in third and fourth floors are the same with that in second floor;
h.After connecting and installing the batteries in third and fourth floors, connect one end of the cable A (1 cable) to output switch, and another end to the negative pole of the battery in left rear part;
i.Install the cover board, front and back doors.
j.Connect the cables between the UPS and battery switch and the temperature detection cables that should be shielded cables and should be bound together with power source cables.
k.There are two kinds of installation methods if the UPS needs to be equipped with large capacity batteries ： The first one is to connect multi strings of batteries of same capacity (lower than 100Ah) in parallel, and use the above methods to install the batteries. The output cables of each battery cabinet are connected to the battery terminals of UPS. The method is used if the required backup time is shorter than 2 hours；The second method is to select high capacity 2V battery. The battery cabinet and connection copper bars are
