attached to the floor following the same steps as in the previous section. Electrical attachments to both the main
cabinet and sidecar should follow the instructions outlined in section 4.9.
4.8.3 Floor Stand Installation Instructions
−Inspect concrete prior to installation; floor stand cannot be bolted on cracked or damaged concrete.
−Bolt the floor stand to the floor using HILTI HIT-RE 500 + HAS 1/2 x 6 1/2 adhesive anchor system. Ensure
