Examples: Installing the brake chopper module and a
cooling fan
Example 1: Installation into generic closure
Note: To ensure proper cooling, the brake chopper module and the cooling fan must be
positioned exactly as illustrated in relation to each other.
1. Attach the brake chopper module (b) to the installation surface of the enclosure. See
Installing the brake chopper module
2. Install the cooling fan (e) using a separate mounting plate (d).
The mounting plate is also used to prevent cooling air recirculation in the cabinet.
Therefore, the plate has to cover the whole cross-sectional area of the cabinet.
