1.
When working on the Inline Controller, always disconnect the supply voltage.
2.
The Inline Controller must only be installed, started up, and maintained by qualified
specialist personnel.
3.
Mount the Inline bus coupler in a control cabinet or metal housing. The minimum
requirement for both items is IP54 protection according to EN 60529.
4.
The Inline Controller must not be subject to mechanical strain and thermal loads, which
exceed the limits specified in the product documentation.

The Inline Controller must not be repaired by the user. Repairs may only be carried out
by the manufacturer. The Inline Controller is to be replaced by an approved controller
of the same type.
6.
Only category 3G equipment may be connected to Inline Controllers in zone 2.
7.
Observe all applicable standards and national safety and accident prevention
regulations for installing and operating equipment.
WARNING: Explosion hazard
Only Inline terminals that are approved for use in potentially explosive areas may
be snapped onto the Inline Controller.
Before using an Inline terminal in a zone 2 potentially explosive area, first check that the
terminal has been approved for installation in this area.
For a list of terminals approved for zone 2 potentially explosive areas, please refer to the
AH EN IL EX ZONE 2 application note.
