Electrical connection

ESD damage!
AttENtION!
Electrostatic discharge can lead to damage to electronic com-
ponents!
Î take care to discharge properly before touching the
inside of the device!
Note
Connecting the device to the power supply must always be the last step
of the installation!
Note
It must be possible to disconnect the device from the mains at any time.
Î Install the mains plug such that it is accessible at any time.
Î If this is not possible, install a switch that can be accessed.
Do not use the device if it is visibly damaged!
The device is equipped with 4 electromechanical relays to which loads such as
pumps, valves, etc. can be connected.
Depending on the product version, the mains cables are already connected to the
device. If that is not the case, please proceed as follows:

Relay 3
23 = conductor R3
22 = neutral conductor N 20
15 ... 19 = ground terminal
The terminals marked 0-10 V / PWM are control outputs for high-efficiency
pumps. Connect the signal cables to one 0-10 V / PWM terminal and one GND
terminal each with either polarity.
0-10 V / PWM 1
1 = signal
2 = ground terminal
0-10 V / PWM 3
5 = signal
6 = ground terminal
Attach flexible cables to the housing with the enclosed strain relief and the cor-
responding screws.
The device is supplied with power via the mains cable. The mains voltage must be
100 ... 240 V~ (50 ... 60 Hz).
The mains connection is at the terminals:
28 = neutral conductor N
29 = conductor L
15 ... 19 = ground terminal
