1 General
These operating instructions describe the safe and
proper way to work with the device. The safety informa-
tion 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 instru-
ment 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 2014/34/EU and are licensed for direct heating
through flange-mounting (conduction) or for room heat-
ing (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 la-
bel. See Technical Data [}Page4] section.
The areas of application are:
• Frost protection
• Condensation protection
• Maintaining temperature
The standard design has a room thermostat integrated in
the connecting cable for frost protection applications or a
safety thermostat for maintaining temperature. If a TAE
is used, the respective operating instructions must be
complied with.
The SMART HEATER HI SYSTEM is used for demand-
ing 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 tem-
perature limiter.
EC type examination certificates PTB 02 ATEX 1041 X
with appendices and supplements in German and Eng-
lish, as well as IEC Scheme Certificate IECEx PTB
07.0052X.

6 Installation
NOTICE
Carefully remove
When removing from the packaging and during trans-
port, the connection line must not be stressed or bent.
If an additional TAE thermostat is switched in series,
then it can be attached to the surface of the heater
(thermal coupling). The minimum distance also needs to
be adhered to here. Refer to the following drawing.
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 EN
60079-14 must be complied with.

Illustration2: Installation example BLOCKTHERM with TAE
and clearance
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.
7 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!
Illustration3: 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.

8 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 commis-
sioned.
CAUTION
Sufficient heat dissipation must be ensured.
Unauthorised 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 in-
stallation instructions are not adhered to.
9 Maintenance
The design of the device does not require any mainten-
ance.
Functional and safety test intervals can be freely selec-
ted by the operator in accordance with the applicable
regulations.
Repairs may only be carried out by the manufacturer in
the factory.
In the dust Ex area, the applicable requirements of EN
60079-17 and EN 60079-19 must be complied with.
10 Troubleshooting
If the heater fails, check the installation. Carry out a con-
tinuity test on the heating circuit. Pay attention to the
connection diagram and switching point of the thermo-
stat!
In the case of overheating, the thermal indicator (see fig-
ure) indicates a discoloration. If more than four fields are
blackened, the heater must be uninstalled and returned
to the manufacturer for inspection.
Illustration5: Temperature indicator
11 Deinstallation
Disassembly may only be carried out by a trained per-
son.
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.
12 Disposal
Disassemble the components of the product, taking the
applicable local labour protection and environmental reg-
ulations into consideration and make sure that the com-
ponents are recycled:
• Scrap metal
• Send plastic elements to recycling
• Sort other components according to their material
properties and dispose of them.
