3.1 SECURITY SYSTEM
The voltage of single-phase motors connected with their switch is 230V and 400V for three-phase.
• The international standards for the drill equipment with diamond recommend to have the energy unit
should be connected to the power through a specific security system, equipped with an adequate residual
interrupter.
• The security system is supposed to have:
- Portable differentials box, with one or more plugs, with a stream cutting residual and a special plug for
drill units with diamond.
- The differential switch, incorporated in the cable, in those countries where the law permits it only for
single-phase motors.
- WARNING: It is not sufficient to have the differential interrupter integrated in the feeding.
Before starting to work, check the security system switch. To do so, proceed as follows:
- Plug the differentials box or differential switch (position 1) ON.
- Press the check-up button (T), the switch should jump to OFF position.
NOTE: If during the work, the stream circuit is burnt, disconnect the machine and stop drilling. Check
the fault and solve it.
3.2 SPECIAL PLUGS
The unit is equipped with a normalised, special plug (ECC) that needs to be connected to a secured
switchboard that has a normalised connection base.
Never remove the plug from the cable nor mount another plug.
3.3 EXTENSION CABLES
-
If you need to use an extension cable, always use cables with earth plug.
-
The plug and the peg of the extension cable should be mounted with an electrical cable with a H07RN-F
rubber outer cover.
-
The extension cable needs to have the adequate length and the corresponding section to the drill power
to avoid high energy consumption.
-
(110/230V) Voltage: if you use an extension between the electrical source and the transformer, the
extension needs to have a 9A.
-
If you use an extension between a transformer and an electrical tool, the extension needs to have a 16A
tension.
-
When using more than one cable to get the desired length, make sure each individual extension has the
minimal Amperes value (A) en function of the length of the cables.
