4.3. Disassembly Cover
Prior to the electrical connection, the plastic cover
must be removed. After having done this the connec-
tion terminals are freely accessible. The connection
for the control and primary circuit is designed sepa-
rately.
Loosen the screws on the plastic cover and under the
yellow fl ap and remove the plastic cover.
The system must only be connected to the
mains and put into operation if the entire
heating system has been fi lled and bled or
the circulating pumps may run dry.
When disassembling the cover, if the control unit has
already been connected it must be ensured that the
connection cable between the control unit and the
central unit is only approx. 1m long. When removing
the cover, the connection cable must not be pulled.
In order to remove the cover completely, the connec-
tion cable must be disconnected.
- Before removing the plastic cover disconnect the
system from the mains.
- Before starting the system, check that the pumps
are soft running.
- Before commissioning the system, tighten the
terminals.
4.4. Power Supply Connection
The power supply connection of the primary circuit
takes places directly on the main switch Q1.
Control power connection:
1 x 230 V/50 Hz
Primary power connection:
3 x 400 V/50 Hz
The supply lines must have the relevant thickness.
For more information, see technical data point on
page - max. power consumption.
All other connections must be established directly on
the microprocessor control board or are already fac-
tory set (see the following pages).
The electrical wiring of additional devices on the out-
put terminals on the control board must be done using
fl exible cables 1.5 mm². End sleeves must be used for
the cabling.
