Installation

Operation under difficult conditions, e.g. on ships or in strong sunlight, requires additional
measures to be taken for correct installation, depending on the operating location.
Further information and instructions on this can be obtained on request from your
designated sales contact.
DANGER! Explosion hazard due to intense heating inside the enclosure!
Non-compliance results in fatal or severe injuries.
▶
Ensure that the distances between Ex e electric circuits and Ex i electric circuits
comply with standards (EN IEC 60079-11).
▶
Select suitable conductors that do not exceed the permissible heating temperature
within the enclosure.
▶
Ensure that the specified cross sections are used.
▶
Attach the core end sleeves properly.
▶
Ensure that the power dissipation value for built-in components is not exceeded
(see the "Technical data" chapter).
DANGER! Explosion hazard due to improper installation!
Non-compliance results in fatal or severe injuries.
▶
Install the device carefully and only in accordance with the safety notes
(see "Safety" chapter).
▶
The installation steps stated below must be carried out very precisely.
The necessary technical details/data on electrical installation can be found in the
following documents:
▶
"Technical data" chapter in these operating instructions
▶
Documentation and data sheets provided by the terminal manufacturers
▶
Documentation and data sheets for the installed devices (e.g. for specifications with
regard to equipotential bonding, earthing and intrinsically safe circuits)
▶
Specification
6.2.1 Conductor Connection
▶
Select suitable conductors that do not exceed the permissible heating temperature within
the enclosure.
▶
Ensure that conductors have the specified cross sections.
▶
Guide the conductor insulation to the terminals (for the stripping length,
see "Technical data").
▶
Do not damage the conductor when stripping the insulation (e.g. by denting it).
▶
Fit the core end sleeves properly using a suitable tool.
▶
If the system is equipped with all possible terminals and live conductors, and the maximum
current load has been reached, ensure that the length of a conductor from the screw
connection to the clamping unit does not exceed the diagonal planes of the enclosure.
