3.5 First use
WARNING!
Staff and equipment may be endangered if the drilling machine is first used by unexpert
staff. We do not take responsibility for damage caused by incorrect commissioning.
Power supply
Connect the main plug of the drilling machine to the power supply.
Check the fuse protection of your power supply to the technical data for the power consump-
tion of the engine.
ATTENTION!
Please pay attention that all three phases (L1, L2, L3) for 400V - drilling machines are
connected correctly.
Most engine failures result from incorrect connection, for instance the neutral connector
(N) is being connected to a phase.
This might lead to the following results:
• The engine does get quickly very hot.
• The engine noise increases, i. e. becomes louder.
• The engine has no power.
When the phases are connected incorrectly, the guarantee is null and void.
ATTENTION!
Drilling machines with frequency converter should not be operated with a CEE plug. Con-
nect the machine permanently to a connection box (see EN 50178/5.2.11.1)
INFORMATION
The frequency converter (driving regulator) might release the FI protected switch of your electri-
cal supply. In order to avoid any malfunctioning, you either need an FI protected switch sensi-
tive for pulse current or and AC / DC sensitive one.
In case of a malfunction or release of the FI protected switch, please check the type installed.
The following signs indicate if you have one of the FI protected switches described above.
We recommend you to use an FI protected switch sensitive to AC/DC. FI protected switches
sensitive to AC/DC (RCCB, type B are adequate for 1 phase and 3 phase fed frequency con-
verters (driving regulators).
An FI protected switch type AC (only for alternating current (AC)) is not appropriate for fre-
quency converters. FI protected switches type AC are no longer used.
