1.22 Special safety instructions
regarding explosion protection
○Always behave so that explosion hazards
are avoided.
○A written work approval from the opera-
tor is required prior to working in poten-
tially explosive areas. Keep unauthorized
persons away
○There must be no indications that parts
of the explosion protection are missing or
are not working. Should such indications
become apparent, switch off the machine
and inform a superior without delay.
○Measures for explosion protection
must never be deactivated, modified or
bypassed.
○Transport damages can result in the loss
of the explosion protection. If transport
damages can be seen, do not assemble
the product nor put it into operation.
○It is forbidden to bring in ignition sources
such as sparks, open flames and hot sur-
faces in potentially explosive areas.
○Check the machine at regular intervals
in line with the operating conditions for
damage which may represent an ignition
risk as well as with regard to correct func-
tioning. An inspection must be carried out
every 12 months at the latest.
○The ignition temperature of the ambient
explosive gas and vapour atmospheres
must be greater than 125 % of the maxi-
mum surface temperature.
○The minimum ignition and glow tem-
perature of the ambient explosive dust
atmospheres must be greater than 150 %
of the maximum surface temperature
○The limits of use related to explosion pro-
tection are clearly defined by the device
categories, gas and dust groups as well
as temperature classes stated in the ex-
plosion protection marking. In any case,
also if dust group IIIC is specified, light-
metal dusts as explosive ambient media
are prohibited
○The filling-level monitoring must be en-
sured by the operator at a high degree of
safety.
○The product may be filled via the res-
ervoir lid only, if there is no potentially
explosive atmosphere. Filling via the fill-
ing port is also possible with a potentially
explosive atmosphere. Connect the filler
pump to the equipotential bonding of the
pump.
○The product may be cleaned only, if there
is no potentially explosive atmosphere.
○The ignition temperature of the lubricant
must lie at least 50 K over the maximum
surface temperature of the components.
○In case of products without electrical fill-
ing level control make sure to check the
lubricant filling level at regular intervals.

951-181-010-EN
Version 06
EN 1. Safety instructions
○Only use tools and clothing which are
permitted for use in potentially explosive
areas (ESD).
○Transport, installation, repairs and work
on electrical components may only be
carried out, if it has been ensured that the
atmosphere is not potentially explosive.
○Repairs or modifications to machines
which are protected against explosions
may be carried out only by the manufac-
turer or by a workshop recognized by a
named institution and confirmed in writ-
ing. If the work is not carried out by the
manufacturer, the repairs must be ap-
proved by a named expert and confirmed
in writing. The repairs are to be marked
by a repair sign on the machine, stating
the following:
- Date
- Executing company
- Type of repair
- If applicable, expert's code
○All parts of the earthing concept must be
correctly available and connected with the
superordinate machine.
○If transport lugs are dismantled after
set-up, the threaded bores must be per-
manently sealed in accordance with the
protection class.
○Handle the materials so that no sparks
generated by tilting, falling, sliding, rub-
bing, impacting, etc. If needed, cover
materials with suitable means.
○Never disconnect plug-in connections
when energized. Secure plug-in connec-
tions against inadvertent manual discon-
nection with the safety clips.
○The operator must check critically wheth-
er operation without a low-level signal
might lead to a new risk potential (e.g.
through heat-up of bearing points on the
machine in the area of ignition tempera-
ture in the case of lacking lubrication).
If this cannot be ascertained, provide a
low-level signal or suitable organisational
measures for monitoring of the bearing
point temperature.
○Avoid dust accumulation and remove
dust immediately. Dust accumulations
have a thermally insulating effect and, if
whirled up, generate the formation of a
potentially explosive atmosphere.
○The product must be integrated in the
operator's lightning protection concept.
○All parts are to be checked regularly for
corrosion. Replace the affected parts.
○Terminal boxes must be firmly closed and
the cable breakthroughs correctly sealed.
○Additional electrical monitoring devices
must be firmly connected and correctly
adjusted.
