Assembly
Unsafe power pack isolation
A standard power pack can supply all system components
with 24 V. An unsafe power pack isolation can 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 05551! 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 on the plug connections
(see Table 5 on page 95) if you do not use a pre-assembled
plug connector.
2. Connect the bus coupler operating voltages using the plug
connector (see "Spare parts and accessories" on page 137).
3. Check the operating voltage specifications using the
electrical characteristics and comply with them (see chapter
"Technical Data" on page 135).
4. Provide power according to Table 6, on page 95.
Select the cable cross-section according to the cable length
and occurring currents.
