2. Ambient temperature:
In order to improve the life and reliability of the braking unit, please install it in a well-ventilated area. If
you install braking units in an enclosure, be sure to size the panel properly and provide adequate
cooling/ventilation as necessary to ensure the internal temperature remains lower than +40˚C.
3. Other precautions for installation:
Before installation, cover the ventilation grills on the braking unit with tape to keep out dust and metal
fragments. After installation is completed, be sure to remove any tape or other coverings from the ventilation
grills.

Provide adequate top, bottom and side clearance around the HBU according to the following diagram:
