The electrical control panel checklist
NOTICE:
The control panel must match the ratings of the electric pump. Improper combinations
could fail to guarantee the protection of the motor.
Check that the following requirements are met:
• The control panel must protect the motor against overload and short-circuit.
• Install the correct overload protection (thermal relay or motor protector).
Pump Type Protection
Three phase electric pump
1
– Thermal protection (must be supplied by the
installer)
– Short circuit protection (must be supplied by the
installer)
2
• The control panel must be equipped with a dry-running protection system to which a
pressure switch, float switch, probes, or other suitable device is connected.
• The following devices are recommended for use on the suction side of the pump:
– When the liquid is pumped from a water system, use a pressure switch.
– When the liquid is pumped from a storage tank or reservoir, use a float switch or
probes.
• When thermal relays are used, relays that are sensitive to phase failure are
recommended.
The motor checklist
WARNING:
• Read the operating instructions in order to ensure whether a protection device is
provided if another motor other than the standard is used.
• If the motor is equipped with automatic thermal protectors, be aware of the risk of
unexpected starts in connection to overload. Do not use such motors for fire-fighting
applications.
NOTICE:
• The mains voltage and frequency must agree with the specifications on the data plate.
In general, motors can operate under the following mains voltage tolerances:
Frequency Hz Phase ~ UN [V] ± %
50 3
230/400 ± 10
400/690 ± 10
60 3
220/380 ± 5
380/660 ± 10
Use cable according to rules that apply for single phase and three phase versions.
4.3 Install the pump
4.3.1 Mechanical installation
Check the following before installation:
• Use a concrete of compressive strength class C12/15 which meets the requirements of
exposure class XC1 to EN 206-1. The subframe must withstand all loads that arise
during operation. To prevent vibrations being transmitted to adjoining components,
1
fuses aM (motor starting), or magneto-thermal switch with curve C and Icn ≥ 4,5 kA or other equivalent device.
2
Overload thermal relay with trip class 10A + fuses aM (motor starting) or motor protection magneto-thermal switch with starting class 10A.
