Motor
The motor connection must meet the local applicable regulations. A thermal safety device should
reduce the risk of a motor overload. For connecting PTC thermistors (if present) a special thermistor
relay must be used. In case of doubt, contact your Bredel representative for advice.
Refer to the documentation supplied with the electric motor for information on how to connect the
motor to your power supply.
Frequency controller
WARNING
A frequency controller that is fitted without manual control can start the
pump automatically when power is applied.
If the hose pump is fitted with a frequency controller, consider the following points:
•
Take precautions so the motor does not restart automatically after an unscheduled stop. In the
event of a power or mechanical failure, the frequency controller stops the motor. When the
cause of the failure is removed, the motor can restart automatically. The automatic restart can
be dangerous in certain pump installations.
•
All control cables outside the enclosure must be shielded and have a cross sectional area of at
2
least 0.22mm
