REMARKS
- Connection with up to 4 load cells of 350 ohms each.
- The combination of two or more Zener barriers (1) GD [Ex ia] means that the Atex marking of the barrier unit must be updated to (2) GD [Ex ib], as required by standard EN 60079- 14.
WARNING
The KIT3 can be placed in an ATEX zone according to the ATEX marking or alternatively in a safe zone.
