NOTICE
Risk of Damage
When removing from the packaging and during trans-
port, the connection line must not be stressed or bent.
The connection cable must be permanently installed up
to the inlet into the on-site junction box, taking the per-
missible bending radius = 5 x outer diameter into consid-
eration.
To ensure operational safety, the heater must operate
under temperature conditions which will NOT exceed the
trigger temperature of the limiter.
The operating temperatures must be adhered to.
INFO
The temperature switch must be installed in a housing
that meets the requirements in accordance with ABNT
NBR IEC 60079-0.
For example:
The TSE must be connected to the radiator using the
fastening screws supplied in order to utilise its equipo-
tential bonding and the thermal feedback.
It must be switched electrically in series with the radiator
in an Ex e junction box.

A 10-A fuse according to IEC 60127-2-1 or a motor pro-
tection switch with short-circuit and thermal instantan-
eous release must be upstream of each temperature
switch as short-circuit protection (setting to 10 A). The
fuse or motor protection switch can be housed in the cor-
responding power supply unit or must be housed separ-
ately upstream. The fuse rated current must be the same
as or greater than the maximum value of the specified
rated voltage (normally UN+10%) of the magnet. The
breaking capacity of the fuse link must be the same as
or greater than the maximum short-circuit current expec-
ted at the place of installation (normally 1500 A).
