The supply voltage and frequency are marked on the
pump nameplate. The voltage tolerance must be
within - 10 %/+ 6 % of the rated voltage. Make sure
that the motor is suitable for the power supply
available at the installation site.
All pumps are supplied with 10 m cable and a free
cable end.
The pump must be connected to one of these two
controller types:
•
a control box with motor-protective circuit
breaker, such as Grundfos CU 100 control box
• a Grundfos LC, LCD 107, LC, LCD 108 or LC,
LCD 110 pump controller.
See fig. 6 or 7 and the installation and operating
instructions for the selected control box or pump
controller.
In potentially explosive environments you have two
options:
•
Use float switches made for Ex environment and
a safety barrier in combination with either DC,
DCD or LC, LCD 108.
• Use air bells in combination with LC, LCD 107.
For more information about the function of the
thermal switches, see section
8.4 Thermal switches .
