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-cir-

cuit.

• Install the correct overload protection (thermal relay or motor protector).

Pump Type Protection

Single phase standard electric pump

≤ 1,5 kW

• Built-in automatic reset thermal-

amperometric protection (motor

protector)

• Short circuit protection (must be

supplied by the installer)

Three phase electric pump and oth-

er single phase pumps

• Thermal protection (must be

supplied by the installer)

• Short circuit protection (must be

supplied by the installer)

• The control panel must be equipped with a dry-running protection sys-

tem to which a pressure switch, float switch, probes, or other suitable de-

vice is connected.

• The following devices are recommended for use on the suction side of

the pump:

• When the water is pumped from a water system, use a pressure switch.

• When the water 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 applica-

tions and sprinkler systems.

NOTICE:

• Only use dynamically balanced motors with a half-sized key in the shaft

extension (IEC 60034-14) and with normal vibration rate (N).

• The mains voltage and frequency must agree with the specifications on

the data plate.

• Only use single-phase or three-phase motors whose size and power com-

ply with the European standards.

In general, motors can operate under the following mains voltage tolerances:

Frequency Hz Phase ~ UN [V] ± %

50 1 220 – 240 ± 6

230/400 ± 10

400/690 ± 10

60 1

220 – 230 ± 6

220/380 ± 5

380/660 ± 10

Use cable according to rules with 3 leads (2+earth/ground) for single phase

versions and with 4 leads (3+earth/ground) for three phase version.

4.4 Install the pump

4.4.1 Mechanical installation

For information about the pump base and anchor holes, see Figure 13.

1. Put the pump onto the concrete foundation or equivalent metal struc-

ture.

If the transmission of vibrations can be disturbing, provide vibration-

damping supports between the pump and the foundation.

2. Remove the plugs covering the ports.

3. Align the pump and piping flanges on both sides of the pump.

Check the alignment of the bolts.

4. Fasten the piping with bolts to the pump.

Do not force the piping into place.

5. Anchor the pump securely with bolts to the concrete foundation or

metal structure.

4.4.2 Electrical installation

1. To facilitate the connection, the motor can be rotated to obtain the

most convenient position for the connection:

a) Remove the four bolts that attach the motor to the pump.

b) Rotate the motor to the desired position. Do not remove the cou-

pling between the motor shaft and the pump shaft.

c) Replace the four bolts and tighten them.

2. Remove the screws of the terminal box cover.

3. Connect and fasten the power cables according to the applicable wir-

ing diagram.

For wiring diagrams, see Figure 14. The diagrams are also available on

the back of the terminal box cover.

a) Connect the earth (ground) lead.

Make sure that the earth (ground) lead is longer than the phase

leads.

b) Connect the phase leads.

4. Replace the terminal box cover.

NOTICE:

Tighten the cable glands carefully to ensure protection against cable

slipping and humidity entering the terminal box.

5. If the motor is not equipped with automatic reset thermal protection,

then adjust the overload protection according to the list below.

• If the motor is used with full load, then set the value to the nominal

current value of electric pump (data plate)

• If the motor is used with partial load, then set the value to the oper-

ating current (for example measured with a current pincer).

• If the pump has a star-delta starting system, then adjust the thermal

relay to 58% of the nominal current or operating current (only for

three-phase motors).

Operation, and Shutdown

Precautions

WARNING:

• Make sure that the drained liquid does not cause damage or

injuries.

• The motor protectors can cause the motor to restart unex-

pectedly. This could result in serious injury.

• Never operate the pump without the coupling guard correctly

installed.

CAUTION:

• The outer surfaces of the pump and motor can exceed 40ºC

(104ºF) during operation. Do not touch with any part of the

body without protective gear.

• Do not put any combustible material near the pump.
