Installation
NOTICE
Carefully remove
When removing from the packaging and during trans-
port, 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.
If an additional TAE thermostat is switched in series,
then it can be attached to the surface of the heater
(thermal coupling). The minimum distance also needs to
be adhered to here. Refer to the following drawing.
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 per-
missible bending radius = 5 x outer diameter into consid-
eration.
In the dust Ex area, the applicable requirements of
ABNT NBR IEC 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 pre-
ceded 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 in-
tegrated thermostat, the fuse protection can be selected
according to the cross-section of the supply cable.
Additional equipotential bonding is required. The ter-
minal block designated for this purpose has the ground
sign.
