4.1 Cable Colors and Pin Assignment (14-wire connection cables)
The electrical connection of the pyrometer (supply voltage and measuring signal) will be done via the
connector on the rear panel. For this purpose, pre-assembled connection cables are available as ac-
cessories (see 9.4 Accessories). To prevent accidental short circuits, cable wires not in use should be
secured to the supplied screw terminals.

NOTE: In general we recommend the use of the current 14-wire connection cables.
Be careful when using an old 12-wire connector cables (before 2015):
Connection cable for the previous models Metis and Sirius cannot be connected without re-
strictions on a M3 / H3 pyrometer!
Old connection cables are bridged in the cable connector to pins E-C and D-F. Connecting such a ca-
ble to a M3 pyrometer, serial interface and analog output 2 and digital input / output 3 are connected
and the galvanic isolation between the outputs is bypassing. Thereby the pyrometer is not destroyed,
but the functions are no longer available. Using such a cable only analog output 1 is available as output.
