• Leakages (e.g. from a shaft seal) of hazardous
fluids (e.g. explosive, toxic or hot) must be con-
veyed away so that no danger to persons or to
the environment arises. National statutory provi-
sions must be observed.
• Danger from electrical current must be eliminat-
ed. Local directives or general directives
[e.g. IEC, VDE, etc.] and instructions from local
energy supply companies must be adhered to.
2.6 Safety instructions for installation and
maintenance work
The operator must ensure that all installation and
maintenance work is carried out by authorised
and qualified personnel who have sufficiently
familiarised themselves with the installation
and operating instructions by studying them in
detail. Work on the product/unit must only be
carried out when it is at a standstill. The proce-
dure described in the installation and operating
instructions for shutting down the product/unit
must be strictly observed.
Immediately after completing work, all safety
and protective devices must be put back in posi-
tion and/or recommissioned.
2.7 Unauthorised modification and manufacture of
spare parts
Unauthorised modification and manufacture of
spare parts will impair the safety of the product/
personnel and void the manufacturer's declara-
tions regarding safety. Modifications to the prod-
uct are only permissible following consultation
with the manufacturer.
Genuine spare parts and accessories authorised
by the manufacturer ensure safety. If other parts
are used, the manufacturer is no longer liable for
any consequences which arise from this.
