4.4.5. Grounding of the Dual Depot Charge Box

PE must be connected to each of the Dual Depot Charge Boxes by 35 mm
2
cable as
described in the IEC 61851-23.

Grounding scheme is dependent on the layout of the specific installation site and
contracted electrical company should define detailed design of grounding installation.
Local legal requirements must be met. Following options of providing PE to the Dual
Depot Charge Box are proposed:

PE may be connected from locally available ground connection in the vicinity
of the Dual Depot Charge Box

PE may be routed from Power Cabinet or distribution board via cable conduits.
In that scenario each Dual Depot Charge Box should have dedicated PE cable.

There are two 35 mm
2
glands in Dual Depot Charge Box used for guiding PE cables
to PE connection points inside the box. Daisy-chaining of ground signal through Dual
Depot Charge Boxes is
not allowed.

If the Dual Depot Charge Box is installed on the pedestal or any other metal
construction which must be grounded, there are two 16 mm
2
glands available to
connect PE of the Dual Depot Charge Box enclosure to the metal frame.
