WARNING
Specication 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
Category 1G 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 500V 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
(KU2 and KU25)
• 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
following ways.
F0203.ai
e.g. In case of selecting “ia” and crossing out “db”
and “tb” and “ic”
e.g. In case of selecting “db” and “tb” and crossing
out “ia” and “ic”
Note 3. Installation
Installation should be in accordance with
Control Drawing IIE029-A63.
