5.5.4 Wiring the host interface
Damage to the interface module!
Electronic components in the CLV can be damaged if the host interface is wired incorrectly.
This also applies for the adaptation of the host interface interconnection in the AMV/S 40
connection module (configuration).
¾
Wire the host interface correctly in accordance with
Fig. 5-2
.
¾
Check the wiring before switching on the CLV.
1. Connect the host interface of the CLV EMC-compatibly to the host by means of shielded
cables. Observe the maximum cable lengths (
Table 5-2, Page 5-2
).
Recommendation 2. Apply the shielding at one end.
In the default setting the CLV communicates via the host interface with the host using the
values listed in
Table 5-6
.
