Installation
NOTICE
Carefully remove
When removing from the packaging and during trans-
port, the connection line must not be stressed or bent.
The label needs to remain legible.
Please make sure that the absolute heat transfer coeffi-
cient of the surrounding housing is not smaller than 0.5
W/K.
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.

scope of delivery (see Installation accessories) 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
