Installation
NOTICE
Carefully remove
When removing from the packaging and during
transport, the connection line must not be stressed or
bent.
For free convection, the heater needs to be installed with
ribs standing vertically. The minimum distances to the
floor and to devices above it must be complied with. The
label needs to remain legible.
For the operation of the device, it is absolutely
necessary to connect an external digital temperature
controller TC… in series with the heater. The controller
housing may only be mounted at a place where 80°C is
not exceeded. See separate operating instructions for
series digital temperature controller TC.
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.
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.
In the dust Ex area, the applicable requirements of EN
60079-14 must be complied with.
Additional installation material, such as rails or panels
and also junction boxes, are not included in the standard
scope of delivery (see
and must be ordered additionally.

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.
Where operating voltage = measured voltage (rated
voltage), then the heater is at its rated output. Mains
voltage fluctuations up to 10 % are then permissible.
Each heater with integrated TS thermostat must be
preceded by a 10 A fuse or a motor protection switch
with short-circuit and thermal quick release (set to 10 A)
as short-circuit protection. When using a heater without
integrated thermostat, the fuse protection can be
selected according to the cross-section of the supply
cable.
Additional equipotential bonding is required. The
terminal block designated for this purpose has the
ground sign.
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
devices with a measured triggering residual current of 30
mA are preferable. In an IT system, an insulation
monitoring device needs to be used which switches off
the supply as soon as the insulation resistance is no
greater than 50 Ω per Volt of the rated voltage (refer also
to DIN EN 60079-14; section 7.4).
ATTENTION:
Never remove the
adapter/ cable gland!
