sufficient ventilation, the RSTi-EP station must be installed while observing the following minimum
distances (refer to the following figures).
Depending on how the station shielding is implemented, the specified
distances may have to be made larger, where necessary.
Attention
The minimum permissible conductor bending radii must also be observed. Earth terminals already
installed can be ignored when calculating the distance.
