Mounting
Notes on mounting
1.
To allow trouble-free servicing, make sure that the following aspects are
fulfilled after KSM has been mounted:
●
Connection points are easily accessible
●
Address selector switches are easily accessible
●
Diagnostic LED is visible
2.
Preferably mount the device to a conductive surface. If this is impossi‐
ble, later on connect the second connection point of equipment ground‐
ing conductor at the device to the equipment grounding system of the in‐
stallation.
3.
For devices of the "W" and "A" cooling types, only the mounting position
G1 is allowed.
Mounting position G1: The air heated inside the component can flow un‐
impeded vertically upward. In the case of components with integrated
fans, the natural convection supports the forced cooling air current.
4.
For the dimensions of the mounting holes, see the dimensional drawing
of the device.
5.
