CALPEDA 6SDX (L) 27/28 [5/32] Electrical connection

CALPEDA B-8SDS 70/5 [5/32] Electrical connection

recommended is 10Nm (for 4” motors).

Attach the cable to the pump with the cable guard

and place the filter on the suction lantern.

Follow separate operating instructions (if available)

of the motor.

4. Electrical connection

Electrical connection must be carried

out only by a qualified electrician in

accor

dance with local regulations.

Follow safety standards.

The unit must be pro-

perly earthed (groun-

ded), also with a non-

metallic delivery pipe.

Make sure the frequency

and mains voltage cor-

respond with the name

plate data.

The

control panel

must

contain:

•

a device for disconnection

from the mains (switch)

with a contact separation

of at least 3 mm in all

poles;

•

an adequate motor pro-

tector for the current

indicated on the name-

plate;

•

a capacitor for the SDM

single-phase pumps, in

accordance with the

data indicated on the

motors themselves.

For pumps with power rating above 11 kW, it is

advisable to provide the control panel with Y/ Δ

or impedance starting.

Install electrodes to protect the pump against dry

running.

4.1. Connection of cables

Feed cables have to be chosen on the basis of

power, distance, voltage drop and temperature.

For connection of cables in the well, use thermo-

shrinking insulation sheathes or other systems

used for submerged cables.

Before lowering the motor into the well, use appro-

priate instruments to measure continuity between

phases and perform an isolation test between each

single phase and the earth conductor.

4.2. Operation with frequency converter

Adjust the frequency converter so that the limiting

values of min. 30 Hz and max. 60 Hz will not be

exceeded.

The maximum running up time from 0 to 30 Hz

and running down time from 30 to 0 Hz for fre-

quency-converter operation is 1 second.

5. Starting

ATTENTION: never run the pump dry,

not even for a short trial run.

Start the pump with the gate valve regula-

ted to minimum

aperture

and wait until the

delivery pipe is completely free of air.

With a three-phase motor make sure

the direction of ro

tation is correct.

For this purpose, with the gate valve at half-open

aperture position, check the pressure (with the

pressure gauge) or flow rate (sight check) after

starting. Switch off power, reverse the connections

of two phases on the control panel, re-start and

check the pressure or flow rate capacity again.

The correct direction of rotation will provide a con-

siderably greater and easily distinguishable pres-

sure and delivery capacity.

Make sure the sand residue present in the water

disappeares or is minimal.

Never start or run the pump when the gate

valve has been opened too widely.

Make sure the pump operates within its rated

limits of performance and that the rated absor-

bed current is not exceeded.

Otherwise, regulate the delivery gate valve or the

setting of any pressure switches.

ATTENTION: avoid long periods of operation

with closed discharge.

5.1. Generator supply

The switching sequence is of utmost importance.

If you do not apply this correctly, both motor and

generator may be damaged.

Therefore:

AIways switch the generator on and off without load!

This means:

- Starting: aiways switch the generator ON first -

and the motor afterwards!

- Stopping: always switch the motor OFF first -

and the generator afterwards!

6. Maintenance

Under normal operating conditions with clean

water the pump will not require maintenance.

Absorbed current and head supplied by the pump

must be checked at regular intervals.

This procedure should be carried out frequently

when water contains considerable quantities of sand.

In the case of emergency systems, it is advisable to

operate the pumps

once a month in order to avoid

the risk of blocking and to maintain and

verify per-

fect efficiency.

Disconnect electrical power

before any servicing

operation.

Changes reserved.
