Point level detection – hygienic/industrial

Electrical connection in explosion hazard areas

Depending on the variant, the LBFH/I is approved for most explosion hazard areas.

DANGER

Risk of fatal accident due to a wrongly connected sensor

In explosive gas atmospheres of zone 0 or 1, use Baumer isolation barriers or Zener barriers.

In explosive dust atmospheres, use insulated cable to IP67.

Allow only persons trained in explosion protection to perform the installation.

Never use FlexProgrammer or IO-Link Master configuration tools in explosion hazard areas.

7.1 Explosive gas atmospheres zone 0 and 1

The LBFH/I can be used in explosion hazard areas of zone 0 or zone 1. Sensors can use Baumer isolation

barriers which are easy to install or use Zener barriers.

Approval for LBFx.xx.xxx.xxxxxx.x.4xxx.x: ATEX II 1G Ex ia IIC T4 Ga

and ATEX II 1D Ex ta IIIC T100 °C Da (TÜV 17 ATEX 188894 X)

LBFx.xx.xxx.xxxxxx.x.4xxx.x and additional

dust atmospheres:

Use insulated cable to IP67.

Secure cables with external strain relief at a

distance 5 centimeters from the sensor.

All LBFH/I in zone 0 and zone 1

Use PROFSI3-B25100-ALG-LS isolation

barriers for the connection.

– or –

Use Zener barriers.

Comply with the following temperatures,

connection values and circuit diagram.

DANGER

Risk of fatal accident due to failing communication with the sensor

IO-Link communication is not possible when a barrier is installed.

Do not use IO-Link communication together with a barrier.
