    2.4.5 Data Backup HEIDENHAIN provides a data backup program called TNCBACK.EXE free of charge. HEIDENHAIN recommends that the machine manufacturer use the software TNCBACK.EXE to save all his machine-specific data to a floppy disk, and that he supply the disk with the machine. The disk must also contain the program TNCBACK.EXE.

    3.2 Shipping Brace of the Hard Disk The hard disks of the MC 422 are fitted with a shipping brace. The shipping brace consists of two screws, which are used to secure the hard disk to the housing of the MC 422. There are also two additional free threaded holes in the housing, into which the screws are inserted after the hard disk has been released.

  • Page 46: Environmental Conditions

    Use of a heat exchanger with separate internal and external circulation. HEIDENHAIN advises against blowing external air through the control cabinet to replace the internal air. Electronic assemblies may be adversely affected by fine dust or vapors. If no other method of cooling is possible, then ensure that the fan extracts the warmed air from the electrical cabinet and that the air drawn in is adequately filtered.
