• A professional instructor is required in the whole hoisting process.
• All the used slings must have the load-bearing capacity of at least 10t.
• The crane should have sufficient arm length and radius of gyration.
• All the connection point must be firmly connected.
• The length of the slings can be adjusted appropriately according to on-site conditions.
• Transport the inverter in a level, smooth, and steady way.
• Transport the inverter by connecting the four top corner fittings.
• Some accessories may be required to ensure the safety during hoisting.
The following figure illustrates the hoisting operations. Circle A indicates the work areas of
the crane. Anybody standing inside the circle B is prohibited for safety considerations.
5.2.2 Hoisting
During the whole hoisting process, observe the following rules:
• Hoist the inverter in a vertical manner. Do not drag or drop the inverter on any surface.
• When the inverter has been hoisted for about 300mm away from the ground, stop to
check if all the connections are still firm. After confirmation, continue hoisting the inverter.
• When transported to the final location, the inverter should be put down slowly and
steadily.
• The final location should be firm, level, and well-drained. The inverter is supported by
four bottom fittings on the ground.
The inverter should be hoisted by using four top corner fittings as shown in the following
figure.
