3.3 Connections
The following points must be followed for the 230V connections:
◼
In case of a fixed mains connection, there must be a switch installed outside
the controller that can disconnect the device from the mains power supply. This
switch is not required if the mains supply is connected using a cable and an
earthed mains plug.
The controllers are designed to operate using a 230V/50Hz. The pumps and
◼
valves to be connected must be designed for this voltage!
All protective conductors must be connected to terminals marked with PE.
◼
The neutral conductor terminals (N) are electrically connected and are not
◼
switched!
The switching outputs (A1/A2) are electronic 230V~ N/O contact. If potential-
◼
free contacts are required, the appropriate corresponding accessories are avail-
able.
3.4 Temperature sensor connection
The SOLAREG II ENERGY devices use PT1000 precision platinum temperature sen-
sors. 2 sensors are required, the third sensor is optional.
Mounting / wiring the temperature sensors:
◼
Mount the sensors on the collector and the storage tank. Ensure proper heat
transfer and use heat-conducting paste if necessary.
Cross-sections for cable extensions (shielded):
◼
- up to 15m 2 x 0.5mm
2
,
- up to 50m 2 x 0.75mm
2
.
The shield is connected to the earth (PE)
Connect the temperature sensors according to the system diagram. The polarity
◼
of both conductors for the temperature sensors is irrelevant.
◼
Sensor cables must be laid separately from 230V wires.
Sensor connection boxes equipped with surge protection should be used for
◼
collector sensors and cable extensions.
