Electrical Connections; Electric Motor - Faggiolati Pumps M420 Instrucciones De Instalacion Y Uso

ENGLISH
- Do not overlook dangers to your
health; follow common hygienic
practices.
- Be aware of risks resulting from
electrical malfunctions.
- Make sure that the hoisting
equipment is in good condition.
- Install a suitable barrier around the
working area.
- Make sure that a fast easy exit to the
open air is available.
- Use a helmet, safety goggles and
protective shoes.
- All the people working in sewage
water pumping stations must be
vaccinated against any diseases that
may be transmitted.
- Never introduce your fingers inside
the suction opening as there is a risk
of injuries due to contact with the
impeller. Keep in mind that the pump
may stop and restart automatically
following the triggering of thermal
protections or of remote control
devices; only the power supply
switch may eliminate this risk.
The pump has been designed to be used with liquids that
may be hazardous to your health. To avoid injuries to your
eyes or skin, comply with the following safety precautions
when operating on the pump:

always use safety goggles and rubber gloves;

rinse the pump well with a hot water cleaning
machine before servicing it;

rinse the different components with clean water
after having disassembled them;

wrap a rag around the oil chamber screw
whenever you have to loosen it, to prevent sprays
from reaching your skin or eyes in the event that
pressure has built up in the pump due to
infiltration of the pumped liquid.
In the event of contact with toxic chemicals, proceed as
follows:

eyes: Rinse immediately with running water for
15 minutes keeping eyelids wide open. Contact an
eye doctor;

skin: Remove the contaminated clothing, wash
skin with soap and water; if necessary, consult a
doctor.
FOLLOW ALL THE OTHER HYGIENIC AND SAFETY
PRACTICES AND
REGULATIONS.
LOCAL RULES AND
HOISTING EQUIPMENT
Suitable hoisting equipment is necessary for lifting the
pump and lowering it inside the well, if possible without
requiring a take-up.
The minimum distance between the lifting hook and the
trap/floor must be 0.8m to allow for the extraction of the
pump from the well.
Oversized hoisting equipment may cause damage to the
pump in the event that it should get jammed during the
lifting operations. Make sure that the lifting equipment is
properly secured.
Danger

ELECTRICAL CONNECTIONS

The entire electric system must be installed by skilled
personnel. Follow local rules and regulations.
Danger
Risk of electric
shock
Remember that the initial input current for direct starting
may be up to 6 times the rated absorption; therefore, make
sure that the fuses or the automatic switches have the
adequate setting.
Warning

ELECTRIC MOTOR

Motor asynchronous threephase squirrel cage type,
insulation class H (180°C). Dry motor, cooled by
surrounding liquid. Protection degree IP 68.
The motor is designed for continuous or intermittent
operation, with a maximum of 15 starts per hour at regular
intervals.
The motor is designed for work with 5% maximum
voltage unbalance between the phases (in compliance with
norms CEI EN 60034-1).
10
WARNING! Keep clear of suspended
loads.
If the cable must be replaced, for
safety reasons, the earth conductor
(yellow-green) must be about 50 mm
longer than the phase conductors.
In the event that the cable should
accidentally come loose, the earth
terminal must be the last one to be
disconnected.
The command and control equipment
cannot be installed inside the sump
pit.
- Any splicing of the supply cable
must be absolutely water proof.
- Make sure that the mains voltage
and frequency correspond with the
pump rating.
- The supply voltage must agree with
the specifications indicated on the
rating plate, with a 10% tolerance.
- Always check the current absorbed
by the pump.
- Make sure that the setting of the
temperature relay does not exceed the
indicated value at page 3.
