1 General
These operating instructions describe the safe and
proper way to work with the device. The safety
information and instructions given as well as the local
accident prevention regulations and general safety
regulations valid in the area of application must be
complied with. These instructions are a constituent part
of the instrument and need to be kept in the immediate
vicinity of the device accessible to personnel at all times.
Before starting any work, the operating instructions
should be read in full.
2 Use
The CP..THERM heaters are manufactured according to
Directive S.I. 2016 No. 1107 and are licensed for direct
heating through flange-mounting (conduction) or for
room heating (convection) in Ex-zone 1 and Zone 2 for
instrument categories G/ D in temperature classes T3 to
T6. You will find the temperature class for your device on
the label. See Technical Data [}Page4] section.
The areas of application are:
• Frost protection
• Condensation protection
• Maintaining temperature
The SMART HEATER HI SYSTEM is used for
demanding heating tasks in explosive areas to maintain
high temperatures in analytical instruments. The
temperature controller TC connected to the electrical
heater has a temperature sensor in the heating coil
serving as a temperature limiter.
Type examination certificates CML 22UKEX1655X with
appendices and supplements in English, as well as IEC
Scheme Certificate IECEx PTB 07.0052X .

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.
For the operation of the device, it is absolutely
necessary to connect an external digital temperature
controller TC… in series with the heater. The controller
housing may only be mounted at a place where 80°C is
not exceeded. See separate operating instructions for
series digital temperature controller TC.
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
permissible bending radius = 5 x outer diameter into
consideration.
In the dust Ex area, the applicable requirements of EN
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 Installation accessories [}Page4])
and must be ordered additionally.
8 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 DIN EN 60079-14; section 7.4).
ATTENTION:
Never remove the
adapter/ cable gland!
Illustration2: 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.

9 Commissioning
If the heater is installed in accordance with the notes in
the Installation [}Page 4] section and Connection [}
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.
10 Maintenance
The design of the device does not require any
maintenance.
Functional and safety test intervals can be freely
selected by the operator in accordance with the
applicable regulations.
Repairs may only be carried out by the manufacturer in
the factory.
All components have to be kept clean and free of dust
and harmful substances that could lead to excessive
temperature rise.
In the dust Ex area, the applicable requirements of EN
60079-17 and EN 60079-19 must be complied with.
11 Troubleshooting
If the heater fails, check the installation. Carry out a
continuity test on the heating circuit. Pay attention to the
connection diagram and switching point of the
thermostat!
In the case of overheating, the thermal indicator (see
figure) indicates a discoloration. If more than four fields
are blackened, the heater must be uninstalled and
returned to the manufacturer for inspection.

Illustration5: Thermo indicator for T4 heaters
12 Deinstallation
Disassembly may only be carried out by a trained
person.
DANGER
Risk of fatal injury from electric current!
If contact is made with live components, there is the risk
of fatal injury.
For this reason, switch off the voltage supply, secure
against being switched on again and check that no more
voltage is present.
Disconnect connection line from the clamps and from the
connection socket, disconnect device from bracket and
remove it.
