Installation and Compatibility

Confirm voltage rating, protection thresholds, transfer delay and the manufacturer's wiring diagram before installation. Compatibility with generator, inverter or UPS supplies must be assessed for the specific equipment.

Installation must be performed by a qualified electrician with suitable protection, earthing and cable sizing. An ATS transfers between available sources; it does not generate backup power or guarantee uninterrupted supply.
