BTS-Ex, non-contacting thermal switch unit
Installation
6 Installation
WARNING
Risk of injury
Please observe, in particular,
Chapter 5 (Safety) when working on the non-
contacting thermal switch unit!
•
Before beginning with the installation, ensure that an isolation of all
components is guaranteed.
•
The fusible plugs protect the turbo coupling against damage due to thermal
overload.
Even when the BTS-Ex is used, it is not allowed to replace the fusible plugs
by blind screws or by fusible plugs with different nominal response
temperatures!
•
Never operate the turbo coupling without fusible plugs!
Mounting and maintenance activities in potentially explosive atmospheres may be
performed under certain conditions only. Among others, the following information has
to be observed:
–
Observe the local setting-up regulations.
–
Any work necessary may only be performed in non-hazardous atmosphere.
–
Take additional precautionary measures if the presence of hydrogen sulfide,
ethylene oxide, carbon monoxide and/or other substances of Explosion Group C
has to be expected. As these substances have a very low ignition power, in such
a case, only non-sparking tools may be used.
6.1 As delivered condition
–
Normally, the switching element with sealing ring,
–
the initiator with mounting flange and
–
the evaluator
are supplied as loose parts together with the turbo coupling.
