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 ABNT NBR IEC 60079-14:2009).
ATTENTION:
Never remove the
adapter/ cable gland!

Example heater with KLE connection
CAUTION
NOTICE: Do not remove adapter/ cable
connection 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.
