6 Electrical connection

Danger!
Electrical connection may be performed only by authorized personnel trained in EMC and with the
device and wiring isolated.
Warning!
For use and operation as per the
2 circuits" must be used.
Attention!
The Electronic-Key adapter is allowed to be connected only 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 terminal assignment (see chapter 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 connecting, the operating organization must ensure compliance with the EMC protection
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 connecting 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!
 Only a screened 100 BaseTX cable, twisted pair, Cat 5 or higher, is permitted for use as the
connecting cable. The maximum cable length is 100 m.
 It may be necessary to provide additional shielding in conditions with a high level of EMC
interference.
 A separate switch may be required for the Ethernet TCP/IP connection.
