## Facts

- Alignment lasers AE-LASER-BEAM (Φ12) and AE-LASER-BEAM/10 (Φ10) should be powered from a dedicated 5 V supply after a failure.
- If the machine has no 5 V rail, add AE-POWER/5/3 (220 V in, DC 5 V 3 A).
- Connect the beam module to the 5 V PSU; feed that PSU L/N from the same L/N as the 24 V supply.
