6.2.2 Drilling Mounting Holes in the Foundation
1. Mark the positions of the mounting holes on the foundation corresponding to the mounting brackets.
2. Drill mounting holes at the marked positions.
6.3 Preparation for Mounting on a Base
Requirements:
☐ Foundation pit and subgrade must be prepared for the installation of the base (see Technical Information "Installation
Requirements ‒ Important Information on Transportation and Installation for Sunny Central 500CP XT ⁄ 630CP XT ⁄
720CP XT ⁄ 760CP XT ⁄ 800CP XT ⁄ 850CP XT ⁄ 900CP XT").
☐ The base must be installed.
Procedure:
1. Lead the AC, DC and data cables through the opening into the base. Route the data cables separately from AC and
DC cables.
2. Seal the opening, e.g. with expanding foam. This will prevent animals from penetrating the Sunny Central.
3. Fill up the excavation pit and level off to ground level.
