3 Mounting the device
3.1 Opening the device
Prior to opening the device, make sure to disconnect the mains voltage and ensure
that it cannot be switched back on again.
3.2 Wall mounting
Secure the controller on the wall. Tighten all screws only as tight as necessary to
prevent damage to the lower part of the housing.
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 output (A1) is electronic 230V~ N/O contact. If potential-free
◼
contacts are required, the appropriate corresponding accessories are available.
3.4 Temperature sensor connection
The SOLAREG PICO 200 devices use PT1000 precision platinum temperature sen-
sors.
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.
The controller must only
be installed in dry and
non-explosive areas. Mounting
the controller on an inflammable
surface is prohibited
