NOTES:
– Connection with up to 4 load cells of 350 ohm each.
– The combination of two or more Zener barriers (1) GD [Ex ia] implies that the Atex marking of the barriers assembly must be update to (2) GD [Ex ib], as required by the EN 60079-14 standard.

WARNING
The KMB4 kit can be placed in ATEX zone according to its ATEX marking or in alternative in a safe area.
The electric coordination, executed for realizing the DCATEXMB4 certificate, involves the use of the LCCB/EXCB6 cable, maximum length of 200m (greater lengths upon price estimate).

Installation examples
