Dangerous voltages
A power pack without safe isolation may lead to dangerous
voltages in the case of a fault. This may damage the system
and cause injuries arising from electric shock.
O
Only use a power pack with safe isolation according to
EN 60747, classification VDE 0551! This ensures that the
electric circuits comply with SELV/PELV electric circuits
in accordance with IEC 60364-4-41.
To connect the bus coupler load supply:
1. Set up the correct pin assignments (see Table 2 on page 50)
on the plug connections if you do not use pre-assembled
cables.
2. Connect the bus coupler operating voltages using the plug
connector (see "Spare parts and accessories" on page 84).
3. Check the operating voltage specifications using the
electrical characteristics and comply with them (see chapter
"Technical Data" on page 83).
4. Provide power according to Table 5, on page 64.
Select the cable cross-section according to the cable length
and occurring currents.
