14 Chapter 2 Installation

In this formula: A is the sectional area of the lead (mm2), ΣI is the total current (A) flowing through the lead, L is the length (m) of the lead loop, △U is the permitted voltage drop on the lead, while K is the conductivity. Kcopper=57. For safety, the voltage drop on the cables connecting battery and load cannot exceed 3.2V.

The sectional area of the lightning protection earth cable should not be less than 6mm2, and that of the DC operation earth cable, usually between 35-50mm2, is determined by user. Take the greatest sectional area among the above 3 earth cables as that of the cable connecting the user earth bar.

3.Purchase materials according to the materials list and inspect the materials, for example, check the heat durability, moisture resistance, flame resistance, and voltage resistance of the cable.

4.The auxiliary materials for power supply installation include expansive bolts, binding strips, and insulating tape.

2.1.5Unpacking

To ensure smooth installation, the power equipment must be carefully inspected when it is unpacked.

When inspecting the equipment, first open the packing case with packing list put in it, take out the packing list, and conduct inspection against the packing label, including the customer name, customer address, machine No., total amount, case No., contract No., etc.

Unpacking and inspection: after opening the packing case, check the goods one by one according to the goods list on the packing label. The checking should include:

1.The number and serial number marked on the packing cases according to the actual number of the packing cases.

2.The correctness of the equipment packing according to the packing list.

3.The number and model of the accessories according to the accessory list.

4.The completeness of the equipment set according to the system configuration.

5.The condition of the goods through visual inspection. For example, check if the

cabinet is damaged, if the cabinet has regained moisture; shake gently the rectifiers and monitoring module to see if the parts and connections have been loosened during delivery.
