Electrical connection
CAUTION!
Lay the connection cable to the electrical cabinet and the cable of the coded connector
from the machine to the electrical cabinet in such a way as to prevent a trip hazard.
WARNING!
The three-phase electrical connection may only be performed by an electrician or under
the guidance and supervision of an electrician.
Connect both coded connectors to the electrical cabinet.
We recommend using crossing plates, tread plates with black-yellow markings to cover
the connection cable from the machine to the electrical cabinet.
Please check that the type of current, voltage and protection fuse correspond to the values spe-
cified. A protective earth ground wire connection must be available.
Min. terminal cross-section per phase and grounding: 2.5mm
2
Electric connected load: 5.4 KVA
Permissible voltage fluctuations in normal operation: +6% -10% Volt
Permissible frequency fluctuations: ± 1Hz (50/60 Hz)
Permissible phase imbalance: 3% or less
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.
ATTENTION!
Check if the drive motor is turning in the correct rotation direction. If necessary, two
phase connections must be swapped.
In the event of an incorrect rotation direction, machine components may be damaged.
The guarantee will become null and void if the machine is connected incorrectly.
Check the fusing (fuse) of your electrical supply according to the technical instructions
regarding the total connected power of the machine.
Firmly connect the machine.
Please check that the type of current, voltage and protection fuse correspond to the values spe-
cified. A protective earth ground wire connection must be available.
Mains fuse 16A.
Observe the notes on the connection for machines with frequency converters.
