Approval Information
Rosemount 8700M Magnetic Flowmeter Platform
IEC EX & ATEX Approval Document

08732-AP02, Rev AA
e. Special Conditions for Safe Use (X):
i. For processes requiring EPL Ga, Gb, Da and Db rated equipment: electrode, grounding ring, and
lining protector materials Titanium and Zirconium are not allowed.
ii. When “Special Paint Systems” are applied, instructions for safe use regarding potential
electrostatic charging hazard have to be followed.
iii. The intrinsically safe 4-20 mA and pulse output cannot withstand the 500V isolation test between
signal and ground, due to integral transient protection up to a voltage of 250VAC. This must be
taken into account upon installation.
iv. Conduit entries must be installed to maintain the enclosure ingress rating of IP66.
v. In order to maintain the ingress protection level on the M3 and M4 electrode housing, the copper
crush washer that seals the electrode access plug shall be replaced when the plug is reinstalled.
The copper crush washer is one time use only.
vi. The flow tube and transmitter are not allowed to be thermally insulated.
vii. The property class of the special fasteners which attach the Magnetic Flow Tube or Transmitter
Remote Junction Box to the Magnetic Transmitter is A2-70 or A4-70 SST.
viii. For information on the dimensions of the flameproof joints the manufacturer shall be contacted.
ix. The Magnetic Flow Meter Tube contains nonconductive liners over the grounded tube. For
process requiring EPL Ga, precautions shall be taken to avoid the liner being charged by the flow
of nonconductive media.
f. Where necessary, the essential characteristics of tools which may be fitted to the equipment
g. List of the standards, including the issue date, with which the equipment is declared to comply:
i. ATEX - EN 60079-0: 2012 +A11, EN 60079-1: 2007, EN 60079-7: 2007. EN 60079-11: 2012, EN

h. Supply wire requirements;
Use 10 - 18 AWG wire rated for the proper temperature of the application. For wire 10 - 14 AWG use lugs
or other appropriate connectors. For connections in ambient temperatures above 122°F (50 °C), use a
wire rated for 194 °F (90 °C).
