.
Load fuse with capacity of above 160A should use M12 or M16 OT terminals for connection. Load fuse with capacity
of 160A or below should use M8 OT terminals for connection. Load MCBs use H shaped tubular terminals for
connection.
3. Purchase materials according to the construction materials list and inspect the materials. For example, check the
heat durability, moisture resistance, flame resistance, and pressure resistance of the cable.
4. For the materials that need to be processed by other factories, the materials and the processing drawings should
be provided in advance for processing.

2.4 Unpacking Inspection
Explanation on packing
One suit of power system is packed up separately in many packing boxes and delivered in suit. There is a printed
packing label on the surface of each packing box. In the box which is pasted a 16K red label on the surface, there is
the packing list of the power system marked with
“packing list storage case”. To inspect the equipment, you should:
1. Open the packing box and take out the packing list.
2. Check against the packing label when delivering the equipments.
3. Check the goods one by one according to the packing label after they arrive at the site.
4. Check the goods according to the packing list and equipment configuration and technical requirements.
Unpacking inspection
To ensure smooth installation, the equipment must be carefully inspected when it is unpacked. The checking should
include:
1. The number and serial number of the packing boxes according to the system packing box number.
2. The correctness of the equipment packing according to the packing list.
3. The number and type of the accessories according to the accessory list.
4. The completeness of the equipment configuration according to the system configuration.
5. The conditions of the goods through visual inspection. For example, check if the cabinet and box are damaged, if
the cabinet and box have regained moisture; shake gently the rectifiers and controller to check if the parts and
connections have been loosened during transportation.
