Functional Check; Available Accessories - Optimum Optiturn TU 2506 Operating Manual

Make sure that the direction of rotation of the drive motor is correct. If the rotational
direction switch is switched to the position to perform clockwise rotations (R) the
spindle needs to rotate clockwise. If necessary, exchange two phase connections.
If your connector plug is equipped with a phase inverter, this is done by turning it by
180°.
The guarantee will become null and void if the compressor is wrongly connected.
ATTENTION!
Bei 230V-Maschinen: Lathes with a 1-phase AC motor or the control via a frequency
converter must not be operated with a CEE plug. Firmly connect the machine to the
terminal box (see EN 50178 / VDE 5.2.11.1) .

INFORMATION
On lathes of the type "VARIO" the frequency converter (driving regulator) might release the FI
protected switch of your electrical supply. In order to avoid malfunction, you either need an Fl
protected switch sensitive for pulse current or AC/DC sensitive.
FI protector switch
In case of malfunction or release of the FI protected switch, please check the installed type.
The following signs indicate if your machine is equipped with one of the FI protected switches
described above.

Type A
300 mA
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 regulator).
An FI protected switch type AC (only for alternating current) is not appropriate for frequency
converters. FI protected switches type AC are no longer used.
