The solar system and actuators (pumps, valve, etc…) may be connected to earth thru the
Earth terminals of the SR controller.
The installation shall comply with applicable safety regulations (including EN60730 standard)
and local installation guidelines, especially the SR device is to be connected via a
disconnection device i.e. a circuit breaker or a detachable external fuse.
Preparing the cable feed
Depending on the type of installation, the cables may
enter the device through the rear of the case or the
lower side of the case .

Connecting the cables
> The terminals are approved for connection of
cables as follows:
- Max wire section for power terminals = 2,5 mm²
- Max wire section for signal terminals = 0,5 mm²
> Only use the original temperature sensors (Pt1000) that are approved for use with the
controller. Observe the following points:
- The polarity of the temperature sensor contacts is not important.
- Do not lay sensor cables close to power cables.
- Sensor cables may be extended (use 0,75 mm² min wires).
> Observe the terminal pinout diagram and system wiring diagrams.
