5.3.2 Foundation Requirements
Pay attention to the high weight of the inverter. Check thoroughly the conditions
on the installation site (mainly the geographical and environmental conditions)
before designing and constructing the foundation.
Improper foundation construction may affect the placement of the inverter, open &
close of the door, and future maintenance. Therefore, the foundation must be designed
and constructed according to the related standard. The dimensions and weight of the
inverter, the cable route, and the future maintenance should be considered at all times.
The following conditions must be met:
• The bottom of the foundation should be firm enough.
• The foundation must be suitable for the weight of the inverter.
• The foundation should be higher than the ground on site to prevent the rain from
damaging the base or penetrating into the inverter.
• Sufficient cross-sectional area and depth of the foundation should be maintained.
The depth is designed according to local soil conditions.
• Cable route should be taken into account.
• According to the cable design of inverter and for easy electrical connection,
establish cable trenches on the bottom of the inverter, i.e. reserve the cable
trenches inside the foundation and pre-bury the wire pipes.
• The dirt dug out should be cleared immediately.
