Connection
WARNING
The heater is only designed for non hazardous
areas.
INTERTEC-Hess GmbH accepts no liability for improper
use.
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.
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.
ATTENTION:
Never remove the
adapter/ cable gland!

CAUTION
NOTICE: Do not remove adapter/ cable
connection to connect up the heater!
This would cause irreversible damage to the heater.

Commissioning
If the heater is installed in accordance with the notes in
the
section and
Page 5]
sections,
then
the
radiator
may
be
commissioned.
CAUTION
Sufficient heat dissipation must be ensured.
Unauthorized covers must be removed as otherwise
there is the risk of the heater overheating.
The heating circuit is permanently disconnected by a
temperature melt fuse which can't be reset if these
installation instructions are not adhered to.
