7 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 read station is only allowed to be connected if it is electrically isolated. Otherwise the read station
may be damaged.
Attention!
If connected incorrectly, the read station may be damaged. Observe the electrical characteristics (see
section 5.4 Technical data) and terminal assignment.
In order to avoid overvoltages at the inputs and outputs, inductive loads must be connected with
freewheeling diodes or other protective devices, for example.
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.
Pin 0V of the supply voltage is electrically connected to the housing in the compact version.
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.
