Switching Inputs And Outputs Ext (X41) - HEIDENHAIN ND 281B User Manual

Switching Inputs and Outputs EXT (X41)

Danger to internal components!
Voltage sources for external circuitry must conform
to the recommendations in EN 50 178 for low-
voltage electrical separation. Connect inductive
loads only with a quenching diode parallel to the
inductance.
Only use shielded cables!
Connect the shield to the connector housing.
