With the trial run make sure that the permissible motor temperature is not exceeded.
The temperature classes of cooler and motor specified in the type label have to be definitely observed.
Only those accessories certified by ATEX and complying with the temperature class (example: thermal switch,
etc.) may be mounted to the oil/air cooler.
Any modifications on the design of the oil/air cooler intended for the use in potentially
explosive atmospheres are not permissible.
