Installation & usage tips
- Isolate mains power before wiring — always follow local electrical rules and use a qualified electrician where required.
- Strip cables to the correct length and tighten the screw terminals securely to avoid loose connections or arcing.
- Fit the transformer in a dry, ventilated location away from direct rain — the unit is for protected indoor/outdoor use (mount under eaves or in an IP-rated enclosure if exposed).
- Check the load of the connected device(s) — keep total current draw at or below 1.25A to avoid overheating and blowing the internal fuse.
Safety & care
- Do not open the molded enclosure — there are no user-serviceable parts inside.
- Replace the integrated fuse only with the correct rating as specified by the installer or supplier.
- If the unit becomes hot, emits unusual smells or trips repeatedly, disconnect immediately and have it inspected or replaced.
- Observe local wiring regulations and use appropriate cable sizes and protective devices (MCB/RCD) where required.
