WARNING
Specic conditions of use
• Electrostatic charges on the non-metallic
parts (excluding glass parts) or coated parts
of the Temperature Transmitter shall be
avoided.
• When the enclosure of the Temperature
Transmitter is made of aluminum alloy, if it is
mounted in an area where the use of EPL Ga
equipment 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.
Note 2. Note for multiple types of protection
(SU2 and SU25)
• For the installation of this transmitter, once a
particular type of protection is selected, any
other type of protection cannot be used. The
installation must be in accordance with the
description about the type of protection in this
instruction manual. Cross out the unnecessary
type of protection on the name plate in the
same ways of ATEX.
Note 3. Installation
Installation should be in accordance with
Control Drawing IIE029-A63.
