1.22 Special safety instructions
regarding explosion protection
ïAlways behave so that explosion hazards
are avoided.
ïA written work approval from the opera-
tor is required prior to working in poten-
tially explosive areas. Keep unauthorized
persons away.
ïThere 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.
ïMeasures for explosion protection must
never be deactivated, modified or by-
passed.
ïIt is forbidden to bring in ignition sources
such as sparks, open flames and hot sur-
faces in potentially explosive areas.
ïCheck the machine at regular intervals for
damage which may represent an ignition
risk.
ïThe ignition temperature of the hydraulic
oil must lie at least 50 K over the maxi-
mum admissible surface temperature of
the components.
ïThe ignition temperature of the ambient
explosive gas and vapour atmospheres
must be greater than 125 % of the maxi-
mum surface temperature.
ïThe minimum ignition and glow tem-
perature of the ambient explosive dust
atmospheres must be greater than 150 %
of the maximum surface temperature
ïThe 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
ïOnly use tools and clothing which are
permitted for use in potentially explosive
areas (ESD).
ïTransport, installation, repairs and work
on electrical components may only be
carried out, if it has been ensured that the
atmosphere is not potentially explosive.
ïRepairs 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.
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
ïTransport 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.
ïAll parts of the grounding concept must
be correctly available and connected with
the superordinate machine.
ïIf transport lugs are dismantled after
set-up, the threaded bores must be per-
manently sealed in accordance with the

ïHandle the materials so that no sparks
generated by tilting, falling, sliding, rub-
bing, impacting, etc. If needed, cover
materials with suitable means.
ïThe operator must check critically
whether operation without a low-level
signal might lead to a new risk potential.
If this cannot be ascertained, provide a
low-level signal or suitable organisational
measures for monitoring of the bearing
point temperature.
