IF50
5 - Electrical connections
WARNING
Turn OFF the power supply before connecting the device.
We recommend connecting the Minus wire of the power supply to earth
potential.
Please note that, under poor earthing and grounding conditions, multiple earth
connections of shields and GND terminals may cause severe problems. In such
cases it may be better to have only one main earthing point for the whole
system.
GND terminals 4, 6 and 12 are connected internally. Depending on the input
voltage and the load of the auxiliary voltage output, the total power
consumption of the unit is approx. 70 mA (see the datasheet).
5.1 Incremental encoders TTL / RS-422
If applicable, the encoder can be supplied by the IF50 converter. If the encoder is
already supplied by a remote source, we recommend fully differential operation,
with no GND connection between encoder and converter (see Figure below).
