5 Installation
NOTICE
Risk of Damage
When removing from the packaging and during
transport, 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
permissible bending radius = 5 x outer diameter into
consideration.
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 EN
60079-0:2009 section1.
For example:
The TSE must be connected to the radiator using the
fastening screws supplied in order to utilise its
equipotential bonding and the thermal feedback.
It must be switched electrically in series with the radiator
in an Ex e junction box.
6 Connection
INFO
The device may only be connected up and secured by a
trained person, taking into account the "rated voltage"
and "rated current" specified on the nameplate.
A 10-A fuse according to IEC 60127-2-1 or a motor
protection switch with short-circuit and thermal
instantaneous 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 corresponding power supply unit or must
be housed separately 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 expected at the place of installation (normally
1500 A).
NOTICE
Danger of overheating
The ambient temperature range of the temperature
switch must not exceed -60°C and +80°C in operation.
NOTICE
Risk of Damage
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.
The connection line of the temperature switch must be
connected in a housing that complies with the
requirements of an approved type of protection in
accordance with EN 60079-0:2009 section 1 if
connected in a potentially explosive atmosphere.
The equipotential bonding or earthing must be ensured
by installing the temperature switch on the entire system.
The temperature switch must be installed in an
additional housing that meets the requirements in
accordance with EN 60079-0:2009.
In a TT or TN system, a residual current device (RCD)
must be used where the measured triggering residual
current does not exceed 100 mA. Residual current
