overload. To ensure proper protection of the motor, the switch should be set for the
winding current absorption given on the data plate in Ampere [A]. The pump may
work without such switch but in case of damage caused by overload, the costs of
repair be covered by user.
The electric installation feeding the pump should be fitted with a
residual current device (RCD) of nominal operating current of I
not grater than 30 mA. The manufacture and the warranter is
released from any liability for damages caused to people or
objects resulting to feeding the pump without proper switch.
Pumps 4SDM, MSC reason short length of cable are supplied

protector and switch ON/OFF. Control box must be connect to pump cable.
Method of connections are showed in inside cover of control box. Cable with
electric plug is connected in factory. User must connect only cable from motor.
the pump is running .
In case of damage to insulation of the feed cable it is forbidden to
use the pump. In such situation contact the warranter to replace the
cable. Mechanical damage is not covered by warranty. Using the
pump with damaged insulation of the cable may lead at least to
flooding of the motor, in the worst case to electric shock.
Before starting the pump check the voltage at the cable end. Note
that
decreases. Permitted decrease of voltage for the applied motors is
±6%.
In order to avoid excessive drop of the voltage select proper cable according to the
motor power, length of the cable. See the table below to choose the right cable:
