2. Power supply requirement and wiring

Range of input voltage:

16KW-----single-phase: 180-240V  

26KW, 50KW, 80KW, 120KW, 160KW, 260KW-----three-phase four-wire system: 320-420V

Don’t connect in wrong way for of causing damaging to the equipment. While mains voltage exceeds limit, please don’t turn on the equipment.

Wire: These series products are of equipment with high power, so please ensure enough wire and reliable wiring to prevent the connection point from generating severe heat due to high contact resistance and joint current. Please choose specification of power cord referring to the following table 1. The power cord is a kind of copper core with withstands voltage 500V. 

Table 1

2       The equipment must be reliable earth connection according to the requirement. The frame must be reliable protective bonding to neutral. It is strictly prohibited to connect the ground wire with the water supply pipe. 

2       The line must be setting by the professional person according to the nation wiring rules. The power supply final stage must install relative air-break switch.

2       Please shut off the power cord when you don’t use the equipment.

3. Requirement for cooling water

The inner of equipment and inductor must be cooled down with clean water to prevent the cooling pipe from blocking. If the equipment supplies water with pump, please install filter screen at pump intake. Temperature of cooling water shall not be higher than 45℃ or it will lead to equipment alarm even overheating damage. Please see table 2 for detailed requirement.

Table 2

II.Method of Installation

Please install according to obvious marks on both sides of the panel. Please install according to the following sketch map if you have any problem.

1. Installation of inductor: For holistic type the inductor connect with secondary joint of main control tank directly; for separate please connect the inductor with transformer well and guarantee good contact. The interface of the transformer and inductor should have no water leakage.

2. Connection of cooling water: The inlet and outlet pipe should be connected reliably according to the tablet indication on the engine case. Please make sure that there are no wrong connection, aleak phenomena and seeper in chassis. Please do not sprinkle water into chassis. If it happens please cut off the power supply and drying it.       

3. Connect to earth: The frame must be reliable protective bonding to neutral with more than 6mm2 copper wires for three-phase four-line system. It should comply with the standard of electric work.

4. Please connect feet switch with the interface of remote control switch.

5. For separate type induction heating equipment please connect the main control tank with the transformer as the line number accordingly. Please connect the induction coil joint with the transformer secondary joint.

III．Turn on and Operation

1. Please choose appropriate induction coil according workpiece heated.

2. Turn on cooling water, examine flux and press of water to make sure them achieve required area. 

3. Turn on the power supply. It is single-phase 220V 50-60Hz for 16KW type and three-phase 380V  50-60Hz for others.

A Open the control switch of the front panel of the equipment and switch on power supply.

I Put the workpiece into the induction coil and then step on the feet switch to start heating.

II Adjust the power control knob to make the heating speed achieve technics requirement.

III Loosen the feet switch after heating finish and then take out the workpiece.

IV Stop heating and close power supply switch and the air-break switch on the switchboard after all    completed. 

a Turnoff the cooling water after 10 minutes.

IV．Operation Precautions

1. Please ensure the casing connects to earth in accordance with the standard of electric work to prevent from electric shock.

2. Dismantle and installation of inductor must be done after stopping heating.

3. Firstly connect the equipment with water and then connect it with power. The inner of equipment and inductor must be cooled down with clean water to prevent the cooling pipe from blocking. If the equipment supplies water with pump, please install filter screen at pump intake. Temperature of cooling water shall not be higher than 37℃ with water flux 10T/h (It is better to use intenerated water), or else will lead to equipment alarm even overheating damage.

4. The equipment must be avoided insolation, drench, dampness and dust. Please carry the serving and maintenance after power off one hour.  

5. Please make sure the induction coil is clean to avoid short circuit between the turns of inductors.

6. The equipment cannot use loop inductor, which will make inductive reactance too low and lead to damage of equipment. Under special circumstance, please consult with manufacturer.

7. The cooling water must be clean without impurity. It is prohibited to be short of water under work condition. Please set a filter at the entrance of suction stroke.

8. Descale the waterway of equipment with the detergent (we supply it) every four months. Please clean immediately when the alarm indicator lamp for water temperature is on frequently or water current from the out water gap is decreased patently.

9. Clean the inner of equipment: Blow it clean with compressed air or blowing machine. Clean the circuit board with brush and then blow it. 

10. Inductor connect board must be polished with a sand paper to keep good electrical conductivity if you replace inductor.
