While drives without explosion protection are primarily focused on compliance with the insulation classes of the motor or brake winding, due to the explosion protection a broader view is required.
The maximum surface temperature is determined by all components of the gearmotor. All of the project steps specified in this manual must be followed so that the brake does not exceed the confirmed maximum surface temperature.
