4.6.6 Terminate Earthing electrodes
Terminate the earth electrodes to the IPU earth Busbar, as
shown in section 4.6.5 Terminate the IPU AC link. If metal
foundation plates are used, terminate to each IPU chassis or
earth busbar.
4.6.7 Terminate low power and data cables
All low-power, field wiring (excluding communications) to the
user unit is to be terminated into terminal block X1 (Figure 12).
Note:
IMI earth reference field wiring terminal is not depicted
in in the following image.

Terminate the IPU unit DC link
1.
Identify
the
DC
output
cables
for
the
rectifier
pack
of
the
power
unit.
Note:
These
are
contained
within
conduit
B,
as
shown
in VersiCharge 175 kW Fast Charger Piping and Cabling.
2.
Measure,
cut,
and
crimp
with
M10
cable
lugs
to
the
DC
mounting points.
Note:
Pull
approximately
2
meters
of
cable
to
allow
termination to the DC terminals.

3.
Measure,
cut,
and
terminate
the
UU
Earth
with
an
M10
cable
lug
to
a
spare
mounting
point
on
the
gear
tray
earth bar.

4.6.5 Terminate the IPU AC link
1. Identify the AC input cables.
Note:
These are contained within conduit A, as shown in
VersiCharge 175 kW Fast Charger Piping and Cabling.
2. Measure, cut, and crimp with M10 cable lugs to
mounting points L1, L2, L3 on load break switch Q0,
located on the bottom-left of the main gear tray.

3. Measure, cut, and crimp the protective Earth with an M10
cable lug to a spare mounting point on the gear tray
earth bar.

CAUTION!
• For EMC compliance, it is important that a local Earthing
electrode is used to bond the chassis of the IPU directly
to ground. This may be in the form of an earth stake, or
if available, can be bonded to pre-existing buried earth
structures.
• To ensure that laws and regulations are adhered to,
prior to installation of the unit a professional review of
local lightning protection requirements must be
performed. As a result, it may be necessary to install
additional earthing electrodes for outdoor installations.
