Opening of the Enclosure

WARNING
Disconnect power supply before installing or servicing these
enclosures.
The lid should be removed by loosening the cover screws with a suitable
tool. Never remove the screws or the compression protection (spacer discs)
from the enclosure cover.

Enclosure Fixing

Mounting feet are attached to the outside of the enclosure. The fixing hole
has a diameter of 8 mm (for drawing details refer to the assembly guideline
document supplied with each enclosure)

Wiring

• For the connection of intrinsically safe and non-intrinsically safe terminals
housed in the same enclosure, then these must be separated by at least
50 mm. This distance can be established using a physical gap or by
distributing the terminal blocks in the appropriate groups.
• The technician performing the installation must observe minimal
creepage and clearance gaps, as specified in the IEC 60079-7 or
IEC 60079-11 standards.
• Insulation of conductors must adhere to the insulation stripping length of
the individual terminal as defined by the manufacturer.
• Observe the national regulations for installation and selection of cables.
• Ensure that any wiring does not interfere with the enclosure lid during
opening and closing.
• The conductor size must not exceed the rated cross-section for the
terminal. The terminal's certified rating limits from the EC examination
certificate must also be observed.
• Where conductors of a smaller cross section than the maximum permitted
in a particular terminal are used, the current rating must be reduced
accordingly.
