The part number and serial number of the control unit can be found on the identification label which is also
located on the bottom of the control unit, see Fig. 4.1. The coding unit has its own part number and serial
number. The coding unit identification label can be found on the side of the coding units printhead housing.
The contact details of Korthofah can be found on bottom of the control unit, see Fig. 4.2.
4.2.2 Power supply
For safe operation, the power cable to the control unit must be connected to a properly grounded single-
phase supply of the appropriate voltage. The power supply must comply with the power supply
information that is written on the back of the control unit, see Fig. 4.2 and refer to section Appendix A.
Fig. 4.2 Power supply information
Verify that no significant potential difference exists between the single-phase protective earth of the printer
and the frame ground of the host machine.
The wire colour code for the supply cable is: BROWN for Line (L)
