Risk of fan damage!
Incorrect connector assignments can cause the
fan to malfunction, or damage it.
•
If you have several fans connected in
series, we recommend routing branches
from the main connecting cable to each
individual fan. Here, note segment length
LS of the cable cross-section used (chap-
ter 4.1). The cable must also be flexible.
Rigid cables must not be routed to the fan.

CAUTION
Check the programming unit connection
and connector assignment carefully.
