German term or phrase: line reactor
Electrical installation of a pump:


The pump cycle rate and thus the fluid output is controlled by adjusting the motor speed, this is achieved by changing the electrical frequency input to the motor between the range of 20 and 80 Hz. A suitable 3PH AC inverter must be used to control the motor speed.

Important! The electric motor is certified for use in a hazardous area between frequencies of 20 Hz an 80 Hz, therefore it is essential that this range cannot be inadvertently exceeded by the operator as this will invalidate the certification
and use of the electric motor.

In a general manner inverters can be connected directly to the power supply line without **line reactors**. But in this case, ensure the following: To prevent damage to the inverter and to ensure its expected life, minimum line impedance that introduces a voltage drop of 1%, as a function of the motor load, should be used. If the line impedance (transformers + wirings) is lower than these values, it is recommended to use a **line reactor**.
