5.4.1 Information for planning the control system
For the electrical connection of the pump set observe the "Wiring diagrams" section.
The pump set is supplied with power cables; it is wired for DOL starting.
The motors can be connected to electrical low-voltage grids with mains voltages and
voltage tolerances to IEC 60038. The permissible tolerances must be observed.
5.4.1.1 Setting the overload protection device
1. Protect the pump set against overloading by a thermal time-lag overload
