ATEX - Special conditions

WARNING

Observe the special conditions for the intended use of EtherCAT Box modules in potentially explosive areas – directive 94/9/EU.

  • The certified components are to be installed with a BG2000-0000 or BG2000-0010 protection enclosure that guarantees a protection against mechanical hazards!
  • If the temperatures during rated operation are higher than 70°C at the feed-in points of cables, lines or pipes, or higher than 80°C at the wire branching points, then cables must be selected whose temperature data correspond to the actual measured temperature values!
  • Observe the permissible ambient temperature range of 0 to 55°C for the use of EtherCAT Box modules in potentially explosive areas!
  • Measures must be taken to protect against the rated operating voltage being exceeded by more than 40% due to short-term interference voltages!
  • The connections of the certified components may only be connected or disconnected if the supply voltage has been switched off or if a non-explosive atmosphere is ensured!

Standards

The fundamental health and safety requirements are fulfilled by compliance with the following standards:

Marking

The EtherCAT Box modules certified for potentially explosive areas bear the following marking:

ATEX - Special conditions 1:II 3 G   Ex nA II T4   DEKRA 11ATEX0080 X   Ta: 0 - 55°C

or

ATEX - Special conditions 2:II 3 G   Ex nA nC IIC T4   DEKRA 11ATEX0080 X   Ta: 0 - 55°C

Batch number (D number)

The EtherCAT Box modules bear a batch number (D number) that is structured as follows:

D: WW YY FF HH

WW - week of production (calendar week)
YY - year of production
FF - firmware version
HH - hardware version

Example with batch number 29 10 02 01:

29 - week of production 29
10 - year of production 2010
02 - firmware version 02
01 - hardware version 01
