Examples: Installing brake resistors and a cooling fan
Example 1: Installation into generic enclosure
Note: To ensure proper cooling, the brake resistors and the cooling fan must be positioned
exactly as illustrated in relation to each other. Make sure that the cooling air does not
circumvent the resistors.
1. Attach two mounting rails (upper and lower) (a) to the installation surface of the
enclosure using four M6 screws per rail.
2. Attach each brake resistor (c) to the rails using four M6 screws.
3. Install the cooling fan (f) using a separate mounting plate (e).
