ELECTRICAL CONNECTION

WARNING! DANGER OF ELECTRIC SHOCK!
Upon opening the housing, live parts are exposed!
Î Always disconnect the device from power supply before
opening the housing!
ATTENTION! ESD DAMAGE!
Electrostatic discharge can lead to damage to electronic components!
Î Take care to discharge properly before touching the inside
of the device! To do so, touch a grounded surface such as a
radiator or tap!
NOTE:
Connecting the device to the power supply must always be the last step of the installation!
NOTE
The Speed option must be set to Off when non-speed-controlled devices such as
valves are connected.
NOTE
It must be possible to disconnect the device from the mains at any time.
Î Install the mains plug so that it is accessible at any time.
Î If this is not possible, install a switch that can be accessed.
If the mains cable is damaged, it must be replaced by a special connection cable which
is available from the manufacturer or its customer service.
Do not use the device if it is visibly damaged!
The controller is equipped with 7 relays in total to which loads such as pumps, valves, etc. can
be connected:
• Relays 1 ... 6 are semiconductor relays, designed for pump speed control:
Conductor R1 ... R6
Neutral conductor N (common terminal block)
Protective earth conductor ⏚ (common terminal block)
• Relay 7 is a potential-free relay (changeover).
Normally open contact R7-A
Normally closed contact R7-R
Centre contact R7-M
Depending on the product version, mains cables and sensor cables are already connected to the
device. If that is not the case, please proceed as follows:
Attach flexible cables to the housing with the enclosed strain relief and the corresponding
screws.
The temperature sensors (S1 to S10) have to be connected to the terminals S1 to S10 and
GND (either polarity).
The cables carry low voltage and must not run together in a cable conduit with cables carrying
a voltage higher than 50 V (please pay attention to the valid local regulations). The cable lengths
depend on the cross sectional area.
Example: up to 100 m at 1.5 mm², up to 50 m at 0.75 mm². The cables can be extended with a
two-wire cable.
The V40 flowmeter can be connected to the terminals IMP and GND (either polarity).
Vor Öffnen Gerät spannungslos schalten!
Isolate mains before removing cover!
