These operating instructions describe the safe and
proper way to work with the device. The safety informa-
tion and instructions given as well as the local accident
prevention regulations and general safety regulations
valid in the area of application must be complied with.
These instructions are a constituent part of the instru-
ment and need to be kept in the immediate vicinity of the
device accessible to personnel at all times.
Before starting any work, the operating instructions
should be read in full.
2 Use
The temperature switches TS and TSE are manufac-
tured according to Directive INMETRO No. 179, of May
18th, 2010 and are intended, among other things, for
controlling the temperature of enclosures or cabinets.
The type TS is installed in the connection line of the radi-
ator at the factory (standard version).
The type TSE is supplied with its own connection line
and must be attached to the radiator with spacing rollers.
Both versions are approved in Ex zone 1 and zone 2 for
device categories G/ D, in temperature class T6.
Product approval number: NCC 17.0101 X

3 Special conditions for safe use
1. A fuse with a rated current of 10 A acc. to ABNT
NBR IEC 60127-2-1 or a motor protection switch with
instantaneous short-circuit or thermal tripping (adjus-
ted to 10 A) shall be connected in series to each
thermostat as short-circuit protection. The fuse or the
motor protection switch may be accommodated in
the corresponding power supply unit or it shall be
connected in series separately. The rated voltage of
the fuse shall be the same as or higher than the
maximum operating voltage specified for the thermo-
stat. The breaking capacity of the fuse link shall be
the same as or higher than the maximum short-cir-
cuit current expected to occur at the place of installa-
tion (usually 1500 A).
2. The ambient temperature range of the temperature
switch must not exceed -60°C and +80°C in opera-
tion.
3. The temperature switch and its connection line
(cable extension) must be set up in such a way that
they are protected sufficiently against mechanical
damage.
4. The connection line of the temperature switch must
be connected in a housing that complies with the re-
quirements of an approved type of protection in ac-
cordance with ABNT NBR IEC 60079-0 if connected
in a potentially explosive atmosphere.
5. The connecting cable shall be of such quality that it
complies with the thermal requirements of the field of
operation.
6. The equipotential bonding or earthing must be en-
sured by installing the temperature switch on the en-
tire system.
7. The temperature switch must be installed in an addi-
tional housing that meets the requirements in ac-
cordance with ABNT NBR IEC 60079-0.
