4.3.2 Wiring the power supply and IM 650
Power cables
Use flexible cables to wire the power supply.
If you use only one cable per connection, an end sleeve is not required.
Connecting comb
Use the connecting comb to wire the PS 307 power supply module with the IM 650. The
connecting comb comes with the power supply module.
Further 24 V connections
On the PS 307 power supply, 24 V connections are still available, by means of the connecting
comb, for connecting the supply of the ET 200PA SMART modules.
