Installation position and minimum distances
Note | |
Mounting specifications To ensure optimum function of the BC9191, observe the following specifications when installing it
|
Installation position
Mount the mounting rail horizontally so that the connection surfaces of the snapped-on BC9191 face forward (see figure Minimum distances).
The BC9191 is then ventilated from bottom to top, which enables optimum cooling of the electronics by convection. "From below" is relative to the acceleration of gravity.
Minimum distances
When mounting, adhere to the minimum distances to other components and the walls of the control cabinet or terminal box employed as specified in the illustration above.
Ambient temperature
Ensure adequate ventilation so that the permissible ambient temperature range for the BC9191 is maintained in the control cabinet or terminal box employed (see Technical data)!
