ELECTRIC CONNECTION:
The electric network from which the pump is to be supplied should have nominal
values as given in the date plate of the motor.
The pump must be connected to the network with active earthing.
The manufacturer and the warrantor is released from liability for
damages to people or objects resulting from the missing proper earthing.
The electrical network feeding the pump must be fitted with an
installation over-current motor switch securing the motor against
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
n
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 with separate control box equipped with capacitor,
overload 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.

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 at farther parts of the cable at its end the supply voltage
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:
