EMC measures
The PE conductor connection is also used to conduct interference currents
away from:
S
S
S
To ensure that these interference suppression measures are effective, there
must be a low-resistance connection between the shielding plate and ground
potential.
The low-resistance bonding conductor should be a fine stranded cable with a
cross-section of at least 10 mm
DMP compact
No more than 8 DMP compact modules can be connected per NCU terminal
modules block.

Maximum number of components in all terminal blocks of a controller:
Important
!
No more than 4 analog outputs and 4 analog inputs can be plugged in at the
same time for each NCU terminal block.
Caution
!
After the load supply voltage for the DMP compact modules has been switched
off during operation, the outputs do not reliably reestablish through-connection
when the load supply voltage is switched on again. If switch-off during
operation cannot be avoided, the DMP outputs have to be reset via the PLC
program when the load supply voltage is switched off. The outputs are set
again after the voltage has been switched on again.
