Frequently Asked Questions
Q: Does the module support user‑replaceable fuses A: No. The fuse is built‑in and not user‑replaceable.
Q: What happens during a brief input voltage interruption A: Interruptions of 10 ms or shorter are tolerated without output drop.
Q: Is the RUN relay output suitable for external alarms A: Yes. It can drive 24 VDC, 0.5 A loads such as small relays or signal lamps.
Field Installation Guidelines
Use properly sized 0.75–2 mm² conductors and approved RAV terminals. Maintain separation between power wiring and low‑level signal cables. Ensure stable 24 VDC supply to avoid triggering over‑current or over‑voltage protection. Confirm LED indication before commissioning downstream modules.
