4.2.2. Connecting the mains cables
The HYC_50 charging stations can be used in TT and TN-S, TN-C and TN-C-S type supply
networks.
Attention
The necessary protective measures against electric shock and other
country-specific requirements must be taken into account and
implemented before commissioning the charging pole.
This product is designed for type A environments (interfering emissions),
the immunity is equivalent to type A environments.
Depending on the mains voltage and the configuration of the HYC_50, a
protective earth current of up to 300 mA may flow. This must be taken
into account when designing the protective earthing and protective
measures.
This product can cause a DC current > 6 mA in the protective conductor.
Where a residual current-operated protective device (RCD) is used for
protection against electrical shock, only an RCD of Type B or B+ is
allowed on the supply side of this product.
An I
N
= 300 mA is recommended.
Any optionally connectable external signals may only be designed and
connected as SELV signals.
After the HYC_50 has been mechanically installed (see Chapter 4.1), the mains cables can
be screwed to the isolator at the input.
