6.2. Electrical control pannel requirements
ATTENTION:
The nominal values of the control panel must match those of the electric
motor. Any mismatch would not guarantee motor protection.
Verify if the following requirements are met:
· The electrical control pannel must protect the motor against overload and short-
circuit.
· Install the right overload protection (thermal motor protection relay).
Pump type Protection
Single phase standard
electric pump ≤1,5 kW
· Built-in automatic reset thermal amperometric
protection (motor protection)
· Protection against short-circuit (must be provided
by the installer)
1)
Three phase electric pump
and other single phase
pumps
· Thermal protection (must be provided by the
installer)
· Protection against short-circuit
2)
1) aM fuses (motor start) or thermal switch with curve C and Icn ≥ 4.5 kA or other equivalent device.
2) Overload thermal relay with operation class 10A+ fuses (motor start) or thermal switch with operation class
10A.
· The control panel must be tted with a dry-running protection system to which a
pressure switch, oat switch, probes or other suitable device is connected.
· The following devices are recommended for the suction side of the pump:
· Use a pressure switch when pumping water from a water system.
· Use a oating switch or probes when pumping water from a tank or deposit.
· When using thermal relays, phase-failure sensitive thermal relays are
recommended.
6.3. Wire connections/screwed connection
The following table shows the number and size of lead connections on the connection
box of the pump motor.
6.4. Position of the connections box
The connection box can be installed in two different positions at 90º. Follow the
procedure below to adjust its position:
1. If necessary, remove the coupling protections. Do not remove the coupling.
2. Remove the screws that hold the motor onto the pump.
3. Turn the motor to the desired position.
4. Insert and fasten the screws.
5. Put back the coupling protections.
