Electrical Connection - ZAPTEC Pro Installationsanleitung

Connecting the wires
Connect the cables in the junction box in accordance with
the electrical system at the location. See the illustration
below. The terminal blocks must be tightened to a torque
of 5 Nm.
If you install the system on a three-phase IT network,
we recommend using a 5-wire cable – in case a TN-
transformer is installed in the future. This will mean that

DO NOT DO THIS!
The Backplate rated for
63A connection but not
63A feedthrough!
This is only ok if
installation fuse is
<=40A (like in HOME
installations)
Zaptec Pro installations: DO THIS!
Bottom or top entry of cable
is both OK.

Electrical connection

There are four possible connection variants, depending on whether three-phase
or single-phase is used, and whether a TN network, TT network or IT network
(Norway only) is used, as shown under or on the label on the back plate.

the neutral connection can be
made in the fuse box rather than
on each individual charging
point, which will make it easier
to carry out future upgrades.
3. Koble ledningene i koblingsboksen i henhold til det elektriske
systemet på stedet. Vises i illustrasjonen under. Sukkerbitene
trekkes til med et moment på 5 Nm.
Hvis du installerer på 3-fas IT-nett, anbefaler vi at det benyttes 4
leder kabel i tilfelle det installeres en transformator senere for
bedre ladeytelse. Da kan den nøytrale koblingen gjøres i sikringss-
kapet heller enn på hver enkelt ladestasjon, slik at det blir enklere å
gjøre fremtidige oppgraderinger.
