Terminator
The terminator for the drive bus must be inserted in slot X21 on the last NCU
terminal block.
Protective
In the case of common protection and interference voltage, the protective
conductor conductor regulations according to VDE 0100 and VDE 160 must always be
complied with.
See protective conductor connection in Fig. 7-1.
EMC measures
The protective--conductor terminal is also used to discharge interference
currents from:
S
S
S
To ensure that these interference suppression measures are effective, make
sure there is a low-resistance connection between shield plate and earth
potential.
The low-resistance connecting conductor should be a fine-core conductor with a
cross-section of at least 10 mm
DMP compact
A maximum of eight DMP compact modules can be connected for each NCU
modules terminal block.
