• Position the product with sufficient space around.
• Make sure that the temperature of the cooling air does not exceed 50 °C.
• Keep cooling fins and fan blades clean.
4.1.3 Installing the product in moist surroundings
If you install the motor in moist surroundings or areas with high humidity, ensure that the bottom drain hole is open. As a result, the
motor becomes self-venting, allowing water and humid air to escape.
4.1.3.1 Drain holes
The motor has a plugged drain hole on the drive side. The drain hole is placed in the flange on the drive side. You can turn the flange 90 ° to
both sides or 180 °.
With the drain hole open, the motor becomes self-venting, allowing water and humid air to escape.
When you open the drain hole, the enclosure class of the motor will be lower than standard.
