1. Terminal connection schemes
Power supply + KNX powering
LM5p-PMC has 3 power supply inputs:
- 1. Power supply to power LM5 + KNX line
- 2. Power supply to power LM5 + KNX line (backup)
- 3. Power supply to power LM5 itself (backup)
All three power supplies should be on one phase except if you are using galvanically isolated
power supplies (for example, transformer-based). If they are galvanically isolated you can
connect to three different phases each of them. If there is no necessity to power KNX line, you
can use 3. power supply only.
