The second option is to daisy-chain the electrical connection through each of the Dual Depot
Charge Boxes, as shown in the one line diagram below.

Grounding of the Dual Depot Charge Box can be connected the Power Cabinet’s or to
another available ground connection, such as buried ground electrode. This should be taken
into consideration while preparing civil works.
3.9. Civil installation
NOTICE
The instruction presented in this section assumes that the cable
connections between the Power Cabinet and the Dual Depot Charge Box
are located below the ground.
Depending on the location - e.g. If the HVC-R 100/150 E-Bus Charger is
located indoors, the cables can be led above the ground level. In this
case the presence of cables trays is required to protect the cables.
The most suitable option should be chosen by the Contractor performing
the works, as this matter is not resolved in this Installation Guide.
DC power cables, PE wire and data cables must be routed between the Power Cabinet and
the Dual Depot Charge Box. Therefore, two flexible cable conduits with an outer diameter of
maximum 120 mm must be installed between the foundation of the Power Cabinet and the
foundation of the Dual Depot Charge Box.
The DC power cables must be installed inside separate cable conduits with respect to the PE
wire, AC auxiliary power and data cables. The maximum length of the cables between the
Power Cabinet and the Dual Depot Charge Box is 100 m. Both conduits must be at least 600
mm deep in the ground and must be in one-piece.
The AC power cable from the distribution boards can also be installed in a cable conduit (not
mandatory).
