– Ground lug: Use ground lugs made of hot-dip zinc-coated at steel sheet with a
cross-sectional area of 40 mm x 4 mm, and leave 300 mm of each ground lug out
of the concrete platform (same as the height between the foundation and the
ground).
– Before the installation, remove the tinfoil from the ground lugs.

4.2.5 Securing the ESS
Step 1 Open the door of the control unit cabin to get the angle steels in the carton.
Secure the ESS using four angle steels.
● There are four mounting holes where angle steel brackets contact the base.
Mark all mounting holes.
● Each angle steel bracket must be secured by two mounting holes. It is
recommended that the outer two mounting holes be used. If steel bars in a
concrete base block the drill bit or when the position deviation occurs during
the
rst drilling, use the inner mounting holes.
● Ensure that the expansion bolts are tightened when securing the angle steel to
the base.
