FAQ
Quick answers. Detailed wiring, safety, and commissioning procedures are supplied by the OEM or your distributor on request.
Which document should I trust for compliance and wiring?
This page and the PDF datasheet are marketing/engineering summaries. For terminal layouts, safety warnings, and step-by-step commissioning, ask sales for the current OEM manual package for your region.
How do I maximise battery life?
Battery endurance depends on reporting interval, signal quality, and sensor load. Follow the manual’s guidance on antenna placement and upload cadence tuning.
Where do I get warranty support?
Warranty and after-sales terms are provided with your order and in OEM documentation — use Contact Information for the policy that applies in your territory.
