circuit in zone 2 or 22,
5. Usage
WARNING : Misuse will cause the loss of warranty and manufacturer’s responsibility.
The load cells are only allowed for professional applications in accordance with the load cell data sheet and
Flintec application parts.
a) If the load cells are not, powered from an intrinsically-safe circuit the connection cables must either be
lead out of the hazardous area to terminate them or terminated in suitable junction boxes.

d) The load cells type BK2, PC1, PC22, PC42, PC46, PC60, SB5, SLB, UB5, ULB and ZLB have a plastic
surface > 4 cm
2
. If used in zone 0 precautions against electrostatic charging must be implemented.
e) In zone 0 and in the apparatus group IIC the connecting cables of the load cells must be laid
protectedly against static charges
