Specific Condition of Use:
–
Electrostatic charges on the non-metallic parts (excluding glass parts) or coated parts of
the Temperature Transmitter shall be avoided.
– (ATEX) When the enclosure of the Temperature Transmitter is made of aluminium alloy, if it is
mounted in a potentially explosive atmosphere requiring apparatus of equipment category 1 G is
required, it must be installed such that, even in the event of rare incidents, an ignition source due to
impact and/or friction sparks is excluded.
– (IECEx) When the enclosure of the Temperature Transmitters is made of aluminium alloy, if it is
mounted in a potentially explosive atmosphere requiring apparatus of equipment EPL Ga is required,
it must be installed such that, even in the event of rare incidents, an ignition source due to impact
and/or friction sparks is excluded.
– The dielectric strength of 500 V r.m.s. between the intrinsically safe circuit and the enclosure of the
Temperature Transmitter is limited, only by the removable surge absorber F9220AR.
WARNING–ELECTROSTATIC CHARGE MAY CAUSE AN EXPLOSION HAZARD.
AVOID ANY ACTIONS THAT CAUSE THE GENERATION OF ELECTROSTATIC CHARGE, SUCH AS
RUBBING WITH A DRY CLOTH ON COATING FACE OF THE PRODUCT.
Note: The surge absorber F9220AR can be removed from, or added to the equipment.
