9.5 KNK03, KMV03, KLC03
9.5.1 Arranging the devices
Mount the KMV supply unit to the left of the KNK mains filter. The connection
points at KMV then can be accessed and wired more easily.
9.5.2 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
impossible, later on connect the second connection point of equipment
grounding conductor at the device to the equipment grounding system
of the installation.
3. For devices of the "W" and "A" cooling types, only the mounting position
G1 is allowed.
4. For the dimensions of the mounting holes, see the dimensional drawing
of the device.
5. Data of the mounting screws:
Devices of "B" or "I" cooling type:
● Thread: M5
● Tightening torque: 6 Nm
Devices of "A" or "W" cooling type:
● Thread: M6
● Tightening torque: 6 Nm
Cold plate
Devices of cooling type "B" are mounted on a cold plate.
Required cold plate properties:
See chapter 9.1.3 "Cold plate" on page 279.
9.6 Electrical connection
9.6.1 General information
High electrical voltage! Danger to life by
electric shock!
Working within the range of live parts is extremely dangerous. Therefore:
● Any work required on the electric system may be carried out only by
skilled electricians. It is absolutely necessary to use power tools.
● Before starting work, the system must be de-energized and the power
switch be secured against unintentional or unauthorized re-energization.
● Before starting work, the appropriate measuring equipment must be
used to check whether parts of the system are still under residual
voltage (e.g. caused by capacitors, etc.). Wait to allow the system to
discharge.
