the use of this manual.
The installation must be performed by qualied
personnel that have read this manual and opera-
te in accordance with the guidelines IEC 60364.
Otherwise it may result in injury or dangerous si-
tuations when dealing with electricity.
NOTICE
Work may not be performed when it is raining or
the air humidity is higher than 95%.
NOTICE
A charging station should always be installed on
a dedicated circuit.
NOTICE
Danger to life through improper installation!
Non-observance of the following installation and
environmental requirements can lead to dange-
rous situations when dealing with electricity.
! DANGER!
The electrical system must be dead (disconnec-
ted from the power supply) during all installation
and maintenance work.
! DANGER!
3.2 Requirements for assembly and
installation
Cables should be laid based on maximum char-
ging rate of the charging station under conti-
nuous load (no diversity). The cable diameters
in this manual are indicative. The technician is
responsible for determining the correct cable dia-
meter and compliance with applicable standards.
NOTICE
Make sure that the following requirements for the
installation of the ICU Compact are fullled:
• The cable route from the main distribution to the
ICU Compact must be secured with a miniature
circuit breaker (MCB) with characteristic B or a
screw or blade fuse gG against overvoltage and
short circuit
• The cable route must be secured against acci-
dental contact 30 mA by a type A or B-residual-
current circuit breaker
• The cable route and the charging station are
part of a TN-S system; the device is grounded
via the main distributor
• The cable route must be laid in accordance with
applicable standards
• The cable tray is made of copper cable with
a maximum conductor temperature of at least
90 °C
Installation requirements may be dependent on
the location.
