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.
or
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
.

8.2 CU 100 control box
The CU 100 control box incorporates a motor-
protective circuit breaker and is available with level
switch and cable.
Single-phase pumps
Connect a run capacitor to the control box.
For capacitor size, see the table:
DANGER
Electric shock
Death or serious personal injury
- Prior to installation and the first startup
of the pump, check the cable for visible
defects to avoid short circuits.
A possible replacement of the cable must
be carried out by Grundfos or a service
workshop authorised by Grundfos.
