Subject to change without notice
● Carry out potential equalization according to EN/IEC 60079-14 (see also the following
Section).
● "Conduit" systems must comply with the requirements in EN/IEC 60079-14, Section
9.4 and 9.6. In addition, compliance with national and other relevant standards is
required.
● "Conduits" according to IEC 60614-2-1 or IEC 60614-2-5 are not suitable.
● "Conduit" systems must be protected against vibration.
● Use thread sealant according to EN/IEC 60079-14, Section 9.4 for threads with ½" NPT.
The following applies additionally for the FLSE100-EXS intrinsically safe cable connection to
intrinsically safe ultrasonic transducers/probe:
● The device marking must at least include the information Ex [ib] or Ex [ia].
● Use only cables delivered by SICK.
The connections of the intrinsically safe ultrasonic probes are designed so that the individ-
ual circuits are safely separated from other intrinsically safe and non-intrinsically safe cir-
cuits.
If the transducer circuits are disconnected while energizing, it still must be observed that the
safe separation from other intrinsically safe and non-intrinsically safe circuits is not overrid
-
den and thus intrinsic safety endangered. For this reason, the associated connection cable
should be disconnected at both ends, i.e. unplugged individually and successively, first from
the electronics and then, if required, from the ultrasonic probes, or suitably attached to pre
-
vent uncontrolled movement of the cable with the unprotected, open cable connector. The
cables for the intrinsically safe components are marked either with ”Exi” or a blue cable cov
-
ering or with blue shrink sleeves on the cable ends or with the SICK item number, at least on
the associated packaging. The technical safety data are shown in the Type Examination Cer
-
tificate.
● Operation of the FLSE100-EXS with sensors not belonging to the system and compo-
nents and sensors from other manufacturers is not permitted. See the Type
Examination Certificate for the technical safety data. See the relevant list in these
Operating Instructions for the sensors which may be used with the FLSE100-EXS.
Specific requirements for installation in USA and Canada
● Installations in USA must be carried out according to NEC (ANSI/NFPa70)
● Installations in Canada must be carried out according to CEC part 1.
● Install sender/receiver units as follows:
– FLSE100-EXS and FLSE100-EXPR sender/receiver units according to manufacturing
drawing E_41943 in the appendix.
– FLSE100-EX and FLSE100-EXRE see manufacturing drawing E_41944 in the appen-
dix.
Special requirements for use of MCUP control unit in Cl I, Div 1
Wiring that enters or leaves the system enclosure must utilize wiring methods suitable for
Class I, Division 1 Hazardous Locations, as appropriate for the installation.
NOTICE:
Keep cover tight while circuits are alive.
Seal required within 18 inches.
