3 General safety instructions
3.1 Safety Instructions for Assembly and Operating Personnel
The operating instructions contain basic safety instructions to be observed during instal-
lation, operation and maintenance. Non-observance will endanger persons, plant and the
environment.
Before assembly/commissioning:
XRead through the operating instructions.
XGive adequate training to the assembly and operating personnel.
XEnsure that the contents of the operating instructions are fully understood by
the personnel in charge.
XThe national installation and assembly regulations (e.g. IEC/EN 60079-14) apply.
If you have questions:
XContact the manufacturer.
When operating the device:
XEnsure the operating instructions are made available on location at all times.
XObserve safety instructions.
XObserve national safety and accident prevention regulations.
XOnly run the device according to its performance data.
XMaintenance or repair work not described in the operating instructions must not be per-
formed without prior agreement with the manufacturer.
XAny damage may compromise the explosion protection.
XNo changes may be made to the devices or their components that compromise explo-
sion protection.
XInstall and use the device only if it is undamaged, dry and clean.

3.3 Conformity to Standards
The Ex d enclosures in light metal comply with the following regulations and standards:
XDirective 94/9/EC
XEN 60079-0, EN 60079-1, EN 60079-7, EN 60079-11, EN 61241-0, EN 61241-1
XIEC 60079-0, IEC 60079-1, IEC 60079-7, IEC 60079-11, IEC 61241-0, IEC 61241-1
4 Designated Use
The enclosures are used to build motor starters, control stations and terminal boxes.
They are suitable for being mounted in measuring equipment and customer-specific con-
trol panels.
This technology allows using sparking and arcing equipment in zones 1 and 2. The built-
in components are standard electrical and switching devices, being designed and wired
according to customer specifications.
The enclosure units can be installed as components in Ex e control systems. A typical
application is as circuit breakers for motor protection in light and heating circuits.
Covers with inspection windows, O-rings for guaranteeing type of protection IP66 as well
as mounting plates and simple DIN rails are available as accessories.
Flameproof cable glands for directly introducing the cable into the enclosure or threaded
holes for conduit connection are possible. For indirect cable entry, however, enclosures
with terminal compartments of "Increased safety" of the series 8146 and 8125 are used.
WARNING
Only use the device for its intended purpose!
ZOtherwise, the manufacturer’s liability and warranty expire.
XOnly use the device under the operating conditions described in the operating instruc-
tions.
XThe device must only be used in areas subject to explosion hazards according to
these
operating instructions.

Ex e terminal compartment:
8 Installation
)To prevent condensation in the terminal compartment, we recommend using
a type 8162 breather from R. STAHL Schaltgeräte GmbH. The installation of
the breather reduces the type of protection as per IEC 60529.
If installed vertically, breather at the bottom, the type of protection is IP 66,
otherwise IP 54.
WARNING
Danger due to not approved cable entries!
ZIf a not approved cable entry is used, explosion protection can no longer
be guaranteed.
XUse only cable entries approved for the required type of protection.
WARNING
Danger due to open holes or unused cable entries on the Ex e enclo-
sure!
ZThe explosion protection can no longer be guaranteed if holes or unused
cable entries of the Ex e enclosure are left open.
XClose open holes using stopping plugs certified in accordance with Direc-
tive 94/9/EC (e.g. type 8290) and unused cable entries using plugs certi-
fied in accordance with Directive 94/9/EC (e.g. type 8161).
WARNING
Installation may only be performed by qualified personnel!
XInstallation of the devices may only be carried out by appropriately authorised and
trained personnel.
XObserve the relevant national regulations in the country of use.
WARNING
Incorrectly installed components!
ZExplosion protection cannot be guaranteed any more if the components
are incorrectly installed.
XWhen terminal sleeves are fitted, they must be gas-tight and applied with
a suitable tool.
WARNING
Use of cable entries without strain-relief!
ZExplosion protection cannot be guaranteed any more if cable entries are
installed without cable strain-relief in the vicinity of loosely laid cables and
leads.
XSecurely lay cabling and leads.
XIf the cables are laid loosely, only use cable entries approved for this appli-
cation.
WARNING
Danger due to damaged threads!
ZIf threads are damaged, the spark protection gap can no longer be guar-
anteed.
XHandle and fit the cover with care.
XReplace a cover or enclosure with damaged threads immediately!
