7. ELECTRIC CONNECTION.
The table saw is built under IP54.
The switch-Plug that these machine incorporate under voltage protection that prevents unexpected start of the table
saw.
In the event there is a power outage or a voltage drop that stop the machine, and once restored to normal conditions
of supply, the engine will not start until you press the green button to start.
7.1 SINGLEPHASE ELECTRIC MOTOR
Circular saws for wood assembled with single-phase motors, incorporate an electro mechanical brake disc stop in the
engine.
The switch has a single phase switch including thermal protection. The objective of such protection is to prevent the
engine burns down on intensity, so that stops its operation when for some unforeseen cause the temperature rises
more than allowed, if this does happen it is necessary to check the machine and the installation to locate the cause.
Once settled, let the engine to cool down to its normal operating temperature and rearm the thermal protection
operating the small button located at the bottom of the switch.
The engine will restart by pressing the green button.
The extension cord used to power the machine must have a minimum area of 3x1, 5 mm2, up to 25 meters. For a
greater distance we will use 3 x 2.5 mm2.
7.2 THREEPHASE ELECTRIC MOTOR
Circular saws for wood mounted with three phase motors, incorporate an electro mechanical brake disc stop the
engine, the machines are equipped with three phase switches.
The extension cord used to power the machine must have a minimum area of 4 x1, 5 mm2, up to 25 meters. For a
longer distance will be use 4 x 2.5 mm2.
Circular saws come with three-phase motor connected from by factory default to operate at 400V . When
you have a supply voltage of 230V , change the position of the bridge chips in the motor terminal box, as shown in the
figures following connection:
WARNING: In order to change the position of the bridge chips in engines, disconnect the machine from the
main supply; you should also change stickers indicating supply voltage, to agree with the change made.
• The machines with electric motor should always be connected to a standard electrical box that has a
breaker and a differential in accordance with the characteristics of the engine:
2.2kw /3 HP, single phase to 230 V, 20A breaker and differential 20A/300mA
3kw/4 hp, 230V three-phase, 20A breaker and differential 20A/300mA
3kw/4 hp, 400V three-phase, 15A breaker and differential 15A/300mA
