Instruction and Operation Manual for ATEX

This section covers only the ATEX-relevant aspects of the product.
Refer to SLS510 ATEX certificate KEMA 13ATEX0081 or KEMA 13ATEX0082. When load cells are considered in type of protection
non-sparking Ex nA, they need to be fitted in an enclosure that complies with the equipment's of clause 6 of EN60079-15. With a
permanent marker place a mark (√) in the box on the load cell label to indicate the applicable protection (KEMA 13ATEX0081 or KEMA
13ATEX1082). Once selected it may not be changed.

YELLOW
The intrinsically safe circuit including the load cells must be built up with approved safety barriers or switch amplifiers matching the
connected weighing indicator.

2.3 Information for Connections

a. The resistance between all safety ground connections and the system grounding electrode must not exceed 1 ohm.
b. If applying as intrinsically safe, the load cells must be interfaced with an approved safety barrier matching the entity parameter of the
load cells.
c. If applying as intrinsically safe, equipment connected to the safe side of the barrier shall not be powered by or generate more than
250VAC.
