Electric shock due to wrong power pack
A power pack without safe isolation may lead to dangerous voltages,
which may result in injury from electric shock or system damage.
O
Only use the following power supply for the bus coupler:
24 V DC PELV circuits in accordance with DIN EN 60204-1/
IEC 60204-1.
The PELV power source must be a safety isolation transformer
in accordance with IEC 61558-1 or IEC 61558-2-6, or a power
source offering the same degree of safety as a safety isolation
transformer.
Make sure that the power supply of the power pack is always
less than 300 V AC (outer cable – neutral wire).
To connect the bus coupler power supply:
1. If you do not use pre-assembled wiring, connect the plugs
according to Table 6 on page 65.
2. Connect the power supply to the POWER X10 connection (3) on the
bus coupler.

3. Check the operating voltage specifications using the electrical
characteristics and comply with them (see "Technical Data" on
page 78).
4. Ensure that the maximum power can be supplied according to
Table 7, page 66. Select the cable cross-section according to cable
length and maximum current.
