Compliance & installation notes

• Certifications referenced by resellers: CE / FCC / CB — confirm applicable marks for your market and the specific variant before sale or installation.
• Power supply and variant differ by part number: verify whether your SKU includes internal PSU (O‑STD) or requires external 12 VDC panel supply (P). Refer to the official datasheet for exact mounting, wiring and environmental limits.
• Installation should be performed by a qualified technician. Observe local regulations and recommended earthing practices. For battery use, follow battery manufacturer instructions and local battery disposal rules.
