Note on instructions
When working in hazardous areas, the safety o
f
personnel and equipment depends on compli-
ance with the relevant safety regulations. The
people in charge of installation and mainte-
nance bear a special responsibility. It is essen-
tial 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 type 07-662.-…./…. potentiometer consists
of a metal Ex d enclosure, into which an inser-
tion potentiometer is fitted.
The metal Ex d enclosures are tailored to the
dimensions of the resistors and will be pro-
duced in different sizes from Ø 30 to 60 mm
(1.18 to 2.36 in).
The potentiometer can be fastened and secured
against twisting in a number of ways. Two nuts
are included in each consignment. Optionally
BARTEC provides either threaded holes in the
front panel of the enclosure or an antirotation
pin.
Accessories, such as rotary and pointer knobs,
scales, digital drives for 10 turns potentiometer,
and slip clutches could be delivered.

Safety instructions
The potentiometer may be used only within the
specified temperature class and the tempera-
ture range indicated for it (see type label).
The potentiometer is not suitable for use in
zones 0/20.
The potentiometer may be operated only if it is
clean and not damaged in any way. Dus
t
deposits exceeding 5 mm (> 0.2 in) must be
removed.
Utilization in areas other than those specified
and the opening or modification of the product
by anyone other than the manufacturer are not
permitted and will exempt BARTEC from liabil-
ity for defects and any further liability.
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
installation and operating conditions must be
observed. The specifications on the type label
must be adhered to.
Observe the applicable laws and directives
when commissioning or restarting operation.
Always follow the safety instructions on the
operating equipment.

Transport, storage
Damage to the potentiometer through incor-
rect transport or incorrect storage.
Transport and storage is permissible in
original packaging only.
Assembly / disassembly
Risk of serious injury due to incorrect
proceedings.
Only authorized and qualified personnel
may do any of the assembly, disassembly,
installation and commissioning work.

A
lways disconnect the device from voltage
before assembly/disassembly.
When assembling the device, take care that the
distances between the outside edge of the
flame-proof gap and the fixed obstacles that
are not part of the device are for:
Gas/vapour sub-group
IIC IIB
at least 40 mm
(1.58 in)
at least 30 mm
(1.18 in)
The potentiometer must be fitted into an enclo-
sure that conforms to the requirements of a
type of protection recognized as being in ac-
cordance with IEC/EN 60079-0.
When fitting into an enclosure with “Ex e” type
of protection the clearance and creepage
distances under IEC/EN 60079-7 Section 4.3,
Section 4.4 and Table 1 must be observed.
Installation
Death or serious injury due to improper use.
Extensions or modifications to the potenti-
ometer are only permissible if the manufac-
turer’s approval is obtained first.
The IEC/EN60079-14 must be observed.
Check at the installation:
When connecting cables and conductors
to operating equipment with the “Ex e”
type of protection, use Ex-certified cable
entries that are suitable for the respective
types of cables and conductors. They
must conform to the “Ex e” type of protec-
tion and have a suitable sealing element
uphold the device’s protection class.
Connect metallic cable entries to the
earthing system.
Seal unused cable entry holes with Ex-
certified stopping plugs.
When connecting directly to the flame-
proof enclosure, use Ex-certified entries
that are suitable for the enclosure capaci-
ty, the gas sub-group and the conductor.
Take care when connecting conductors:

A
lways use suitable crimping tools when
crimping the wire-end ferrules to ensure a
consistent quality of pressing each time.
Take care not to damage the individual
wires.
Tighten all terminal points securely (in-
cluding those not in use).
Commissioning
Before commissioning, check that:
The device has been installed in compli-
ance with regulations.
The device is not damaged.
The connection has been established
properly.
All screws have been tightened securely.
The device functions perfectly.
Operation
Death or serious injury through improper
use.
The potentiometer may be operated only
within the technical limits that apply to it
(see page 1).

Maintenance and fault clearance
Death or serious injury through damaged
flameproof encapsulation.
Replace defective parts in the flameproo
f
encapsulation with original parts immedi-
ately.
Risk of serious injury due to incorrect
proceedings.
Only authorized qualified personnel may
do any of the work relating to maintenance
and fault clearance.
IEC/EN 60079-17 must be observed. It is
recommended to formulate a maintenance
plan according to this standard.
Maintenance work
The operator of the potentiometer must keep it
in good condition, operate it correctly, monitor it
and clean it regularly.
Visually inspect the threaded gap.
Visually inspect the flameproof encapsu-
lation for damage.
Note
In the course of maintenance particular atten-
tion must be paid to checking that the parts
essential for the type of protection and prope
r
functioning are in good condition.
Fault clearance
The potentiometer is defective if the flameproo
f
encapsulation is damaged and/or if one of the
components does not function any longer
In this case:
Replace defective parts in the flameproo
f
encapsulation with original parts immedi-
ately.
Replace or repair the defective compo-
nents with original parts.
Note
Follow the components mounting instruc-
tions/operating instructions to replace or repai
r
the components.
Accessories, spare parts
See BARTEC catalogue.
Disposal
The potentiometer components contain metal
and plastic parts.
The statutory requirements for disposing o
f
