Flanging of Ex standard motor to Ex gear units in accordance with Explosion Protection Directive 2014/34/EU (ATEX)

Question:
What do I need to consider when attaching an Ex standard motor to an Ex gear unit?

Answer:
No special Ex training certificates are required for mounting the Ex standard motor on the Ex gear unit. A qualification for standard mounting and installation work suffices.

Qualified personnel are persons who possess the knowledge to install geared motors and are qualified to do so.
Definitions for such skilled electricians can be found in IEC 364, EN 50110-1 VDE 0105, for example.
These persons must particularly observe the following points and must

  • Avert danger to life and limb for themselves and third parties

  • Ensure the operational safety of the geared motor in the drive system

  • Exclude the possibility of outages or environmental damage caused by incorrect handling

This means that personnel must be trained and that they must adhere to the specifications listed in the operating instructions.
