Safety
WARNING:
• The operator must be aware of safety precautions to prevent physical injury.
• Any pressure-containing device can explode, rupture, or discharge its contents if it is over-pressurized.
Take all necessary measures to avoid over-pressurization.
• Operating, installing, or maintaining the unit in any way that is not covered in this manual could cause

General precautions
Electrical Hazard:
• A certified electrician must supervise all electrical work. Comply with all local codes and regulations.
• Before starting work on the pump, make sure that the pump and the control panel are isolated from
the power supply and cannot be energized. This applies to the control circuit as well.
• Leakage into the electrical parts can cause damaged equipment or a blown fuse. Keep the end of the
motor cable above the liquid level.
• Make sure that all unused conductors are insulated.
• There is a risk of electrical shock or explosion if the electrical connections are not correctly carried
out or if there is fault or damage on the product.
CAUTION:
If the pump is equipped with automatic level control and/or internal contactor, there is a risk of sudden
restart.
Requirements
These general requirements apply for electrical installation:
Cables
These are the requirements to follow when you install cables:
• The supply authority must be notified before installing the pump if it will be connected to the public
mains. When the pump is connected to the public power supply, it may cause flickering of
incandescent lamps when started.
• The mains voltage and frequency must agree with the specifications on the data plate. If the pump can
be connected to different voltages, the connected voltage is specified by a yellow sticker close to the
cable entry.
• The fuses, short-circuit, and circuit breakers must have the proper rating, and the pump overload
protection (motor protection breaker) must be connected and set to the rated current according to the
data plate and if applicable the cable chart. The starting current in direct-on-line starting can be up to
six times higher than the rated current.
• The fuse rating and the cables must be in accordance with the local rules and regulations.
• If intermittent operation is prescribed, the pump must be provided with monitoring equipment
supporting such operation.
• The motor is convertible between different voltages, as stated on the data plate. This conversion is
done on the terminal board.
• The cables must be in good condition, not have any sharp bends, and not be pinched.
• The sheathing must not be damaged and must not have indentations or be embossed (with markings,
etc.) at the cable entry.
• The cable entry seal sleeve and washers must conform to the outside diameter of the cable.
• The minimum bending radius must not be below the accepted value.
• If using a cable which has been used before, a short piece must be peeled off when refitting it so that
the cable entry seal sleeve does not close around the cable at the same point again. If the outer sheath
of the cable is damaged, then replace the cable. Contact an ITT service shop.
12 Flygt 3102 Service and Repair Instructions
• The voltage drop in long cables must be taken into account. The drive unit’s rated voltage is the
2
2
1
voltage measured at the terminal board in the upper part of the pump.
• The screened cable must be used according to the European CE requirements if a Variable Frequency
Drive (VFD) is used. For more information, contact your ITT representative (VFD-supplier).
Earthing (Grounding)
Electrical Hazard:
• You must earth (ground) all electrical equipment. This applies to the pump equipment, the driver, and
any monitoring equipment. Test the earth (ground) lead to verify that it is connected correctly.
• If the motor cable is jerked loose by mistake, the earth (ground) conductor should be the last
conductor to come loose from its terminal. Make sure that the earth (ground) conductor is longer
than the phase conductors. This applies to both ends of the motor cable.
• Risk of electrical shock or burn. You must connect an additional earth- (ground-) fault protection
device to the earthed (grounded) connectors if persons are likely to come into physical contact with
the pump or pumped liquids.
Connect the motor cable to the pump
Installation (Continued)
CAUTION:
Leakage into the electrical parts can cause damaged equipment or a blown fuse. Keep the end of the motor
cable above the liquid level.
1. Entrance cover
2. O-ring
For information about the cable entry, see the Parts list.
1. Remove the entrance cover and the O-ring from the stator housing.
This provide access to the terminal board/closed end splices.
Flygt 3102 Service and Repair Instructions 13
Installation (Continued)
2. Check the data plate to see which connections are required for the power supply:
• Y
• D
• Y serial
• Y parallel
• Y/D
3. Arrange the connections on the terminal board/closed end splices in accordance with the required
power supply.
4. Connect the motor conductors (U1, V1, W1, and earth (ground)) according to applicable cable chart.
The earth (ground) conductor must be 50 mm ( 2.0 in.) longer than the phase conductors in the
junction box of the unit.
5. Make sure that the pump is correctly connected to earth (ground).
6. Make sure that any thermal contacts incorporated in the pump are properly connected to the terminal
block/closed end splices.
7. Install the entrance cover and the O-ring on the stator housing.
8. Fasten the screws on the entrance flange so that the cable insertion assembly bottoms out.
Connect the motor cable to the starter and monitoring equipment
WARNING:
Do not install the starter equipment in an explosive zone or in the sump.
NOTICE:
• Thermal contacts are incorporated in the pump.
• Thermal contacts must never be exposed to voltages higher than 250 V, breaking current maximum
4 A. It is recommended that they are connected to 24 V over separate fuses to protect other
automatic equipment.
The single phase pumps must be equipped with a starter which has start and run capacitors.
A specially Flygt designed starter is required for the operation of single phase pumps. The connection of
the motor cable to the starter is shown in the wiring diagram.
1. If thermal contacts are included in the pump installation, connect the T1 and T2 control conductors
to the monitoring equipment.
Do not connect the T1 and T2 leads to thermal contacts if the temperature of the pumped liquid is
above 40°C (104°F).
NOTICE:
Ex-approved products must always have the thermal contacts connected irrespective of the ambient
temperature.
2. Connect the mains leads (L1, L2, L3, and earth [ground]) to the starter equipment.
For information about the phase sequence and the color codes of the leads, see Cable charts (page
15).
3. Check the functionality of the monitoring equipment:
a) Check that the signals and the tripping function work properly.
b) Check that the relays, lamps, fuses, and connections are intact.
Replace any defective equipment.
