5 Installing the Cabinet on an Underground Base
5.3 Laying the Underground Base
NOTICE
The underground base is heavy. This process requires multiple-person collaboration. Protect the underground base from
•
damage. Any crack or exposure of glass fiber on the post or panel caused by tool collisions is not allowed.
The pre-buried cables (or pipes) must rise slightly above the ground.
•
After the cables (or pipes) are pre-buried, use sealing materials to seal the cables (or pipes) outlet to prevent water
•
intrusion.
•
Gently place the underground base on the
concrete in the foundation pit, and use a spirit
level to level the underground base.
Pre-bury cables (pipes) at the cable hole position on the underground base with the help of the line-drawing template
for the cabinet (type II).

Lay 75-mm-deep concrete (with the same

underground base. Use a spirit level to level the
underground base.
