Electrical connection
CAUTION
Material damage caused by improper electrical connection!
- An inadequate mains design can lead to system failures and cable fires due to
mains overload!
- If the wrong voltage is applied, the pump can be damaged!
- Applying incorrect voltage to SELV lines will result in incorrect voltage in all pumps
and on-site building automation devices, which are connected to SELV lines!
▪ When designing the mains supply with regard to the used cable cross-sections and
fuses, pay special attention to the fact that, in multi-pump operation, it is possible that
all pumps operate at the same time for short periods!
▪ When switching the pump on or off using an external control device, deactivate any
mains voltage pulse (e.g. burst-fired control)!
▪ Check switching the pump via triacs/solid-state relays on a case-by-case basis!
▪ Make sure that SELV lines have a maximum voltage of 24 V!
DANGER
Risk of fatal electrical shock!
Even if the LED is not illuminated, voltage may be present inside the control module!
Failure to install safety devices (e.g. module cover of control module) can cause
electrical shock, potentially resulting in life-threatening injuries!
▪ Always deactivate the power supply from the pump and if necessary SSM and SBM!
▪ Never operate the pump without having closed the module cover!
NOTICE
Nationally applicable guidelines, standards and regulations as well as the require-
ments of local energy supply companies must be observed!
CAUTION
Material damage!
Wrong connection of the pump leads to damage to the electronics.
Observe the current type and voltage on the rating plate.

▪ Observe the current type and voltage on the rating plate.
▪ Minimum back-up fuse: 16 A, slow-blow or circuit breaker with C characteristic.
In the case of double pumps, individually connect and secure both motors.
▪ It is recommended to protect the pump with a residual-current device (type A or B as
per EN 60335).
Take into account the leakage current per pump I
▪ Exclusively connect to 230 V TN or TT low-voltage mains.
Never connect to 230 V IT low-voltage mains (230 V "Isolé Terre" low-voltage mains).
▪ Establish electrical connection via a fixed connection cable equipped with a connector
device or an all-pole switch with a contact opening width of at least 3 mm (VDE 0700/
Part 1).
