Please carefully read these instructions before installing and operating the Infresco unit. Positioning and Mounting 1. Positioning: Ensure the Infresco unit is positioned with the three fixed cable glands facing downward to prevent water ingress. 2. Mounting: Securely fix the unit using the four mounting holes accessible from the front. Use round cables to avoid water ingress. Wiring It is recommended that the installation and maintenance of this equipment be performed by suitably qualified/trained personnel, referencing the current edition of the I.E.E. wiring regulations (BS7671). These regulations contain important requirements regarding the Warning! Isolate the mains supply before commencing any work on the unit. Failure to do so could result in serious injury or fatality. Cable Glands: The unit is fitted with three cable glands. Only one cable should be fitted per gland to maintain the unit’s IP rating. For connecting four lamps, refer to the ‘Wiring Diagram’ on the next page for an alternative configuration using two junction boxes. Mains Supply Connection: Connect the mains supply to the terminal block marked ‘LINE’. o Live (L) to ‘L’ terminal o Neutral (N) to ‘N’ terminal o Earth (E) to ‘E’ terminal Lamp Connection: Connect the lamps to the terminal block marked ‘LOAD’. o Live (L) to ‘L’ terminal o Neutral (N) to ‘N’ terminal o Earth (E) to ‘E’ terminal Earth Continuity: Ensure all earth wires are connected to maintain earth continuity to the lamp fittings. Final Check: Verify all wiring connections and ensure the cable glands are tightened.
