Mounting the Unit 1. Secure the Infresco-S 4kW using the four mounting holes accessible from the front of the unit. 2. Remove the lid to access these mounting holes. 3. To facilitate installation, use the provided mounting template on the next page to locate all four mounting hole centres. IMPORTANT: Position the unit with the cable glands facing down. Wiring 1. Safety Warning: Ensure all earth wires are connected to maintain earth continuity to the lamp fittings. Isolate the mains supply before wiring this unit. 2. The unit is fitted with two cable glands. Only one cable should be fitted per gland to maintain the unit’s IP rating. When fitting two lamps, refer to the wiring diagram for an alternative wiring configuration using a junction box. 3. Mains Supply Connection:

  • Connect the supply LIVE to the ‘L’ terminal.
  • Connect the supply NEUTRAL to the ‘N’ terminal.
  • Connect the supply EARTH to the ‘E’ terminal. 4. Lamp Connection:
  • Connect the load LIVE to the ‘L’ terminal.
  • Connect the load NEUTRAL to the ‘N’ terminal.
  • Connect the load EARTH to the ‘E’ terminal. If two lamps are to be fitted, they must be wired in parallel. 5. Check all wiring, particularly the line and load connections, and ensure the cable glands are tightened. Fusing 1. It is recommended to use fast-acting semiconductor-type fusing (or MCB) in line with the LIVE supply for device and circuit protection. 2. Refer to the SRA Datasheet X10255 for further information on fusing requirements. By following these steps carefully, you can ensure the safe and efficient installation of your Infresco- S 4kW controller. MOUNTING TEMPLATE

The rear of the enclosure contains the PCB; this will need to be removed before attempting to fit the additional cable gland. Remove the four fixing screws and remove the PCB. The ‘knock-out’ can then be removed and the additional gland fitted as shown above. This should be done very carefully - ensure the gland is tightened up using a spanner. Refit the PCB and secure with the screws. Remove the link that is fitted into the INPUT/COM terminals and wire in the switch wires. Once the additional gland has been fitted the units should be mounted as shown above. This is the only time the unit should be mounted in this way. If the additional switch is not being used, then the unit must be fitted with the gland facing down. Once the unit is wired, the lid should be refitted as shown.
