Note!
Unused inputs on activated channels have to be connected to the respec-
tive ground. This is not necessary when the unused channels are turned off
by means of FFh.
The following circumstances may cause damages at the analog module:
• The module must always first
be power supplied via backplane bus
before connecting the external power supply (current/voltage) to the
front connector.
• Parameterization and connection of the input must always be congruent!
• You must not apply a voltage >15V to the input!
