Note on instructions
When working in hazardous areas, the safety of personnel and
equipment depends on compliance with the relevant safety
regulations. The people in charge of installation and maintenance
bear a special responsibility. It is essential that they have an exact
knowledge of the applicable rules and regulations.
The instructions provide a summary of the most important safety
measures and must be read by everyone working with the product
so that they will be familiar with the correct handling of the
product.
The instructions have to be kept for future reference and must be
available throughout the expected life of the product.
Description
The ComExflex potentiometer, type 07-3373-4***/****, is used
in almost all hazardous (potentially explosive) areas where
machine functions are controlled by means of adjustable voltage
distributors.
The ComExflex potentiometer can be combined with a
potentiometer actuator (scale graduation 0 to 10). A junction
box is available as a safe and convenient means of installing the
potentiometer in a control panel.
The conductors are connected by means of terminals on the back
of the ComExflex potentiometer which have an increased safety
level.The easy installation of the potentiometer actuating element
without the need for tools ensures conformance to the high IP
degree of protection.

Safety Instructions
The ComExflex potentiometer and the corresponding actuator
may be used only within the specified ambient and operating
temperature range. Incorrect installation can cause
malfunctioning and the loss of explosion protection. Utilization
in areas other than those specified or the alteration of the
product by anyone other than the manufacturer will exempt
BARTEC from liability for defects or any further liability. Only
service technicians who are authorized to work in potentially
explosive atmospheres may do any of the assembly, disassembly,
installation, commissioning, maintenance, and fault clearance
work.
The generally applicable statutory rules and other binding
directives relating to workplace safety, accident prevention and
environmental protection must be observed.
When using electrical systems the relevant regulations on
installation and operation must be complied with.
When setting up or operating explosion-resistant electrical
systems, the IEC/EN 60079-14 (NEC for USA/CEC for Canada)
and all relevant installation and operating regulations must be
observed.
The ComExflex potentiometer may be used only if it is in a clean
and undamaged condition. It is not permissible to modify the
ComExflex potentiometer in any way.
Marking
Particularly important points in these instructions are marked
with a symbol:
DANGER indicates a hazardous situation which, if not avoided,
will result in death or serious injury.
WARNING indicates a hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION indicates a hazardous situation which, if not avoided,
could result in minor or moderate injury.
NOTICE is used to address practices not related to personal
injury.
NOTE Important instructions and information on effective,
economical and environmentally compatible handling.
Standards conformed to
See Attestations of Conformity 01-3370-7C0001.
Transport, Storage
NOTICE
ComExflex potentiometer damage through incorrect
transport or incorrect storage.
• Transport and storage is permissible in original packaging
only.
• Store the ComExflex potentiometer in a dry place.
Assembly, Installation
WARNING
Risk of serious injury due to incorrect proceedings.
• The IEC/EN 60079-14 and further national standards
and locally applicable installation regulations have to be
observed.
• Ensure that the voltage supply has been isolated or take
suitable protective measures.
• Pay attention to the type of mounting required (for fitting
into enclosure/attachment with junction box).
Assembly
WARNING
Risk of serious accidents due to damaged parts.
• Before assembly, ensure the perfect condition of the
components.
Mounting the ComExflex potentiometer:
– Make sure the ComExflex potentiometer to be fitted is intact
(no cracks).
– Position the ComExflex potentiometer’s bayonet connector at
the mounted actuating element
– Turn the closing latch to connect the ComExflex potentiometer
securely to the potentiometer actuating element.
NOTE The assembly of the potentiometer actuating element
as well as the assembly of the potentiometer and the
potentiometer actuating element is described in the operating
instructions for actuating elements, type 05-0003-00**/****.

Installation
For fitting into enclosure
In hazardous areas in groups I and II the ComExflex potentiometer
must be used:
– In appropriate enclosures with “Ex e” increased safety type
of protection. The clearances and creepage distances under
IEC/EN 60079-7 Section 4.3, Section 4.4 and Table 1 must be
observed.
– In an enclosure that corresponds to another approved type of
protection specified in IEC/EN 60079-0 Section 1.
With junction box
With junction box
The ComExflex potentiometer must be installed as a stationary unit
and with protection against the risk of mechanical damage.
Take care when connecting conductors:
– Strip 40 mm (1.6 in) sheath off the conductor.
– Remove approx. 6 mm (0.2 in) conductor insulation from the
cores.
– Prepare the ends of fine-stranded and multi-stranded
conductors:Crimp wire end sleeves with suitable crimping
tools. Connection cross-sections: 0.75-2.5 mm2 (14-18 AWG).
– Release terminals.
– Insert conductors diagonally.
– Tight the terminals with a maximum torque of 0.4-0.7 Nm
(0.3-0.5 lb.ft), while holding the screwdriver slightly at an
angle.
Commissioning
Before commissioning, check that:
– The ComExflex potentiometer has been installed in compliance
with regulations.
– The ComExflex potentiometer is not damaged.
– The connection has been established properly (make sure the
cores are secure).
Operation
WARNING
Risk of serious accidents due to operation without an
actuator.
• The ComExflex potentiometer may never be operated without
an actuator at rated voltages > AC 50 V to a max. AC/DC 320
V.
• If the ComExflex potentiometer does not have an actuator, it
must be deenergized.
The ComExflex potentiometer may be operated without an actuator
only at rated voltages of ≤AC 50 V resp. < DC 120 V.
Maintenance and Fault Clearance
WARNING
Risk of serious injury due to incorrect proceedings.
• IEC/EN 60079-17 must be observed. It is recommended to
formulate a maintenance plan according to this standard.
• Ensure that the voltage supply has been isolated or take
suitable protective measures.
Maintenance
WARNING
Risk of serious accidents due to damaged parts.
• Check potentiometers, potentiometer actuating elements,
actuators, sealings, and cables regularly for cracks and
damage. Make sure that they are properly established.
NOTICE
Potentiometer/potentiometer actuating element damage
due to incorrect cleaning.
• It is not allowed to clean ComExflex potentiometers/
actuators with compressed air.
The operator of the ComExflex potentiometer must keep it in good
condition, operate it properly, monitor it and clean it regularly. The
owner/managing operator must schedule maintenance intervals
which will suit the respective conditions of use.

Fault Clearance
WARNING
Risk of serious injury due to use of non-original spare parts.
• Use original parts only as replacements.
The ComExflex potentiometer is defective if turning it does not lead
to a change in resistance.
Defective ComExflex potentiometers cannot be repaired; they must
be replaced considering this operational instruction.
A defective actuator can be taken off the potentiometer and
replaced by a functioning actuator of the same type.
NOTE For original parts, contact the firm of Bartec GmbH at
the service address.
Accessories, Spare Parts
NOTE The ComExflex potentiometer can be connected to a
junction box. Information on the junction box and junction box
assembly is described in the Operating Instructions for the
junction box, order number 05-0042-0050.
For further accessories and spare parts, see BARTEC catalogue.
Disposal
NOTE Environmental damage can be caused by incorrect
waste disposal. When in doubt, local authorities or
specialist disposal companies can provide information on
environmentally friendly disposal.
The components in the ComExflex potentiometer and the
potentiometer actuating element contain metal and plastic parts.
Therefore the statutory requirements for disposing of electronic
scrap must be observed.
