pressure cleaner because the plug-in connection
is not sealed against pressurized water.
In case of malfunctions or failure of the charging sys‐
tem
●
Disconnect the charging system from the power
supply by switching off the respective circuit
breaker in the building. Leave a sign with the
name of the person authorized to switch on the
circuit breaker.
● Call in a qualified electrician immediately.
Electrical devices
● The housing of the charging system must always
be kept closed.
1.5 Installation and tests
Information for selecting protective devices for basic
and fault protection against touching directly or indi‐
rectly
● Electrical circuit breakers
The charging system must be protected with circuit
breakers in compliance with the respective national
regulations. This depends, for example, on the re‐
quired tripping time, internal network resistance, con‐
ductor cross-section, conductor lengths, and the pre‐
set rating of the charging system.
The short-circuit protection of the conductor must have
a characteristic that permits 8-10-fold of the I
nom
value
and must not exceed a maximum nominal current of
16 A, depending on the preset rating of the charging
system.
● Residual-current circuit breaker
For reasons of personal safety, national regulations
may stipulate an upstream RCD with an I
∆N
of
30 mA AC. Choose a suitable RCD that complies with
the national regulations. Heed also the notes from the
section
DC residual current detection
.
● DC residual-current detection
The charging system is equipped with 6 mA DC resid‐
ual-current detection. The charging system switches
itself off if there is a residual current that is greater than
or equal to 6 mA DC. Details of this are given in the
Diagnostics
section.
Information on initial inspections after installation and
repeat inspections
National regulations may stipulate inspections of the
charging system before start-up and at regular inter‐
vals. Perform these inspections in accordance with the
Safety instructions
