1 Safety instructions

Remarks for safe use in hazardous areas.

• The device must only be installed, connected and set up by qualified staff. The qualified staff must

have knowledge of types of protection, regulations and provisions for apparatus in hazardous

areas.

• The classification and marking of the device must be suitable for the application.

• Adhere to the respective national regulations and provisions as well as the relevant installation

regulations.

• Observe applicable documents.

2 Intended use

Type examination certificate:

• EU: BVS 03 ATEX E131 X, BVS 04 ATEX E153 X

• IEC: IECEx BVS 06.0003X

The requirements of the following standards are met:

• EN IEC 60079-0:2018, EN 60079-11:2012

• IEC 60079-0:2017, IEC 60079-11:2011

In principle, the type examination only takes atmospheric conditions into account. For conditions

outside these ranges use must be assessed and approved by the user.

Sensors:

3 Installation

uProtect device and cable against destruction.

uAvoid electrostatic charging on plastic housings and cables.

uTo avoid electrostatic charging, ensure the equalisation of potential of metal parts (connector

housing, fixing elements, protective housing, etc.).

uFor this purpose, the connector housing of the M12 connector (solenoid valve connection) is

connected to pin PE of the connector Rd24X1/8. According to the requirements of the installation

regulations, the connector housing can be grounded via this pin to avoid electrostatic charging, if

grounding is not ensured otherwise.

3.1 Special conditions for safe operation

uAlways refer to the operating instructions for the identification, as it may not be fully applied to the

device due to lack of space.

4 Maintenance, repair and disposal

The device must not be modified nor can it be repaired. In case of a fault please contact the

manufacturer.

If needed, data sheets and type examination certificates or other certificates can be requested from

the manufacturer (Ò cover sheet / back).
