6 Electrical connection
Electrical connection may only be performed by authorized personnel trained in EMC and with the
device and wiring isolated.
Danger!
For use and operation as per the
Warning!
requirements, a power supply for use in class 2 circuits must
be used.
Attention!
The Electronic-Key adapter is only allowed to be connected if it is electrically isolated.
Otherwise the Electronic-Key adapter may be damaged.
Attention!
If connected incorrectly, the Electronic-Key adapter may be damaged.
Observe electrical characteristics and the pin assignment (see section 4.2 Technical data of Electronic-
Key adapter).
Attention!
All the electrical connections must either be isolated from the mains supply by a safety transformer
according to IEC/EN 61558-2-6 with limited output voltage in the event of a fault, or by other equivalent
isolation measures.
Attention!
When installing connections, the operating organization must ensure compliance with the EMC safety
requirements in accordance with EN 55011 and EN 61000-6-2.
Attention!
The equipotential bonding system of the machine installation must comply with EN 60204-1, section 8,
Equipotential bonding.
Attention!
Do not lay connection cables in the immediate vicinity of sources of interference.
6.1 Ethernet connection
The interface for the Electronic-Key adapter is compatible with the standards ISO/IEC 61754-24 and IEC 61158.
The Electronic-Key adapter is operated in full-duplex mode with 10 MBit/s or 100 MBit/s.
Information!
f Only a screened 100 BaseTX cable, twisted pair, Cat5 or higher, is permitted for use as the
connection cable. The maximum cable length is 100 m.
f It may be necessary to provide additional screening in conditions with a high level of EMC
interference.
