Dinel, s.r.o. CLM–36
14 . Safety, protections, compatibility and explosion proof
Level meter is equipped with protection against electric shock on the electrode, reverse polarity,
output current overload, short circuit and against current overload on output.
Protection against dangerous contact is provided by low safety voltage according to 33 2000-4-41.
Electromagnetic compatibility is provided by conformity with standards EN 55022 / B, EN 61326-1,
EN 61000-4-2 to -6.
Explosion proof CLM–36Xi(XiT) is provided by conformity with standards EN 60079-
0:2013+A11:2014, EN 60079-11:2012.
Explosion proof CLM–36Xi(XiT) is verified FTZÚ – AO 210 Ostrava – Radvanice: FTZÚ 02 ATEX
0235X.
A declaration of conformity was issued for this device in the wording of Act No. 90/2016 Coll., as
amended. Supplied electrical equipment matches the requirements of valid European directives for
safety and electromagnetic compatibility.
Special conditions for safe use of variants CLM–36Xi
If the apparatus is used as device of Group II and with using of an approved power supply device,
which output parameters comply with required input parameters, it is necessary to have an galvanic
separation.
When used in zone 0 the present explosive atmosphere of air mixture and gases, vapours of mists
must comply with: -40°C ≤ Tamb ≤ 60°C; 0,08 Mpa ≤ p ≤ 0,11 Mpa.
Design CLM–36Xi can be used in zone 0 or zone 20. With design CLM–36XiT can be used in zone
0 and zone 20 only electrode part an head with electronics can be used only in zone 1 or zone 21.
