If you mount the charging station on a conductive metal
surface, such as a metal pole, you must make a connection
to the earth using an extension wire for the earth (ground)
and the screw at the lower right.
Change the position of the grounding wire from A to B to
ensure grounding.
– Insert the plastic support (this is the IP rubber supplied in
the unit's accessory pack) into the fixing hole (position
"B").
– Secure the grounding cable using an M6 x 30 screw,
which is in the artwork pack. This screw also secures the
unit to a conductive metal surface (where applicable).
Tighten the cable glands before closing the charging sta-
tion cover (See chapter 6.5, "Using the cable glands" on
page 12).
