7.1 Safety instructions
Before connecting an electric motor to the mains, consult the applicable local regulations of the power
supplier and the EN 60204-1 standard.
The electrical system must be equipped with protective measures to ensure that the user can work with
the installation safely at all times.
Before the electric pump is started, the pump must be filled with liquid. Dry running of the pump must be
prevented at all times!
Work may only be performed on the installation when it is completely disconnected from electrical
power. The installation must be protected against inadvertent starting.
WARNING
It is the employer's responsibility to ensure that the pump or pump unit safety
measures (such as protection against excessive current draw) and the resulting
actions (such as shut-down of the pump) are included in the safety circuit.
DANGER
Electrical devices, connection terminals and parts of the control system can be at
mains voltage even during standstill. Contact can result in death, severe bodily
injury or irreparable material damage.
7.2 Connection – general
– Take any necessary measures to ensure that the electrical connections and cables cannot be
damaged.
– The voltage and frequency must be checked in advance and must match the motor specifications.
This data is shown on the type plate of the motor.
– It is not permitted to use the motor without a motor protection switch.
– For frequency controlled motors, make sure there is sufficient starting torque and make sure the
motor is cooled sufficiently at low speeds. Install an independently operating fan if necessary. For the
wiring diagram, see technical specifications BA series.
