System impedances
NOTICE
Maximum switching frequency per hour
The connected motor determines the maximum switching frequency per hour.
- Note the technical data of the connected motor.
- Do not exceed the maximum switching frequency of the motor.
NOTICE
- Depending on the system impedance and the maximum connections/hour of the connected consumers, voltage fluctuations and/or drops may occur.
- When using shielded cables, attach the shielding to the earth rail on one side of the control device.
- Always have connection carried out by a qualified electrician.
- Observe the installation and operating instructions for the connected pumps and signal transmitters.
