Additional installation material, such as rails or panels
and also junction boxes, are not included in the standard
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.
For protection against short circuit and line protection
you can use circuit breakers up to 10 A.
Additional equipotential bonding is required. The ter-
minal 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 monit-
oring 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 60079-14:2008; section 7.4).
ATTENTION:
Never remove the
adapter/ cable gland!

Example heater with KLE connection
CAUTION
NOTICE: Do not remove adapter/ cable connec-
tion to connect up the heater!
This would cause irreversible damage to the heater and
this would mean that the explosion protection can no
longer be warranted.
The illustration may deviate from the heater.
