Remarks
Remarks
Mechanical protection has to be implemented.
Otherwise the unit must be installed together with the impact protection housing (E7000A).
If not pneumatically operated, E75231 sealing plug must be inserted.
Avoid ingress of dirt and dust.
Do not connect any of the following points to an external potential:
L-, L+, I-1, I-2, I-3, I-4
The connections are electrically connected with the AS-i cable.
