ATTENTION!
When delivered the machine is equipped with a plug for electrical connection. It only
serves for acceptance and test purposes. In order to operate the machine it is necessary
to remove this plug and to connect the machine directly with a power supply.
Firmly connect the CNC machine to the terminal box. It is not allowed to connect the machine
using a standard 16A CEE plug, since the stray current of the frequency converter is exceed-
ing the admissible value of 3.5mA (refer to EN 50178 / VDE 5.2.11.1).
ATTENTION!
Depending on the quality of the network, there is a risk of machine malfunctions under
extreme conditions. If necessary and in order to exclude retroactive effects on the
internal power supply system, the operator should install a line filter on the machine.
Therefore, at workplaces with lots of powerful consumers, it might also be necessary to
use a system for network compensation. Please consult your electricity supplier
regarding this.
ATTENTION!
Frequency converters (drive regulators) might trigger the Fl circuit breaker of your
electrical supply. In order to avoid malfunction, an Fl circuit breaker switch sensitive to
pulse current or to universal current may be required.
ATTENTION!
Ensure that all 3 phases (L1, L2, L3) and the ground wire are connected correctly.
The neutral conductor (N) of its power supply is not connected.
