• The foundation should be built in compliance with the foundation drawing provided, or approved, by SUNGROW. The tolerance for the upper surface of the foundation is ±5mm. • The foundation should provide sufficient and effective support for the equipment.
Page 24: Installation Space Requirements
2 Mechanical Installation Quick Installation Manual • Build a cement foundation with sufficient cross-sectional area and height. The founda- tion height should be determined by the constructor based on the on-site geological conditions. • Take cable laying into consideration when building the foundation. In the process of foundation building, remove the muck immediately after exca- vation, to avoid affecting the hoist and transport of the equipment.
