Mounting

Electrical connection conditions

The connection to the electrical power system 

may be carried out only by adequately trained 

expert.

Caution

Neither over voltage nor under voltage should be exceeded by 10%.

 

This unit is intended for operation on a power supply network with a maximum system 

impedance Zmax at the interconnection point (house service line), which is listed in the 

table below in dependence of the performance. The user shall have to ensure that the unit 

is operated only on a power supply network which meets these requirements. If and when 

necessary, the local power supply company can provide information on the system impe-

dance.

Tab. 1: Characteristic value for the electrical connection

The conductor cross sections mentioned are guideline values for a maximum lead length of 50 m 

at a temperature of 30° C. Use a time-lag fuses or “gl fuses”.

•  220 / 240 V systems require a three-core 1P/N/PE cable.

•  380 / 400 V systems require a four-core 3P/PE cable for direct start.

•  380 / 400 V systems require a five-core 3P/N/PE cable for star-delta start.
