Electrical connection in explosion hazard areas

Depending on the variant, the LBFS 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.
f „
In explosive dust atmospheres, use insulated cable to IP67.
f „
Allow only persons trained in explosion protection to perform the installation.
f „
8.1 Explosive gas atmospheres zone 0 and 1
The LBFS can be used in explosion hazard areas of zone 0 or zone 1. Sensors with PNP can use Baumer
isolation barriers which are easy to install. Sensors with NPN must use Zener barriers.
