The electrical connection
u
Check and make sure that the lead is tension-free and meas-
ures have been taken to secure against being switched on.
u
Check and comply with all the requirements necessary for
the connection and mentioned previously in these instruc-
tions.
u
Take the cable gland grommets from the supplied material.
u
Slide the cable bushing over the lead.
NOTE
Ensure that the insertion aid for the grommet is on the
back of the charging station when in the final installed
state, however, do not position it in the housing lead-
through yet.
u
If a data line is also to be connected, use the second sup-
plied cable gland grommet and repeat the above-mentioned
step.
u
Remove the sheathing of the lead.
u
If a rigid lead is used, bend the individual wires paying at-
tention to the minimum bend radiuses so that it is possible
to connect them to the terminals without significant mech-
anical stress.
u
Remove the insulation from the individual wires as shown in
the illustration. (Note: Avoid damage to the conductor).

Charging cable connections
u
Using the slot-head screwdriver (3.5 mm), connect the indi-
vidual cable ends according to the specification in the illus-
tration (Fig. 8) on the left terminal block with the "IN" label.
NOTE
Make sure to connect them using the correct connec-
tion sequence for a right rotating field.
u
To do this, insert the screwdriver in the designated upper
opening of the spring relief for the terminal block and open
the clamping spring.
u
Now insert the individual wire into the designated connec-
tion opening of the terminal block (lower opening).
u
Then remove the screwdriver again and perform a tension
test to ensure that the individual wires are clamped properly
and fully and no exposed copper areas are visible.
NOTE
If multiple charging stations are connected to a com-
mon main power supply point, there is a risk of over-
load.
A phase rotation must be provided and adapted to
the connection configuration of the charging station.
See online configuration manual: https://webasto-char-
ging.com/documentation.
u
Insert the data line into the designated connection in the
connection area. See chapter 3.2.4, "Control cable (Control
Pilot)" on page 6 and Fig. 3.
u
Remove any soiling such as insulation trimmings out of the
connection area.
u
Check again for firm attachment of all wires in the corres-
ponding terminal.
u
Next position the cable bushing in the housing lead-
through.
NOTE
Make sure there are no air gaps between the housing
and the cable bushing.
