Mounting and demounting recommendations
Possibility to be put on a work surface, DIN rail EN 60715 with included clip.
For the most of applications with a built-in switch in a switch board it is possible to recognize
two kinds of environments:
1.
no public and industry environment of low voltage with high interference,
2.
public environment of low voltage without high interference.
For both of these environments it is possible to mount the switch to a switch board if the common
EMC-rules according to EN 60439-1 are noted.
Note!
For compliance with EN 60439-1 ed.2:00 + A1:04 specification when mountin the device to a
switch board, the following points have to be ovserved.
For several cables we recommend to bind the bunch. We recommend for this use:
–
The length of the bunch (combination of power supply and data cables) can be a maximum of
1.5 m. If the length of data cables exceeds 1.5 m or if the cables are lead outside the switch –
board, we recommend installing over – voltage protectors (surge suppressors).
–
Between data cables and cables with reticular tension of ~ 230 V / 50 Hz sufficient space (min.
50 mm) should be kept.
–
A certain space must be kept before the cables for connecting or disconnecting singular ca-
bles.
For correct function of the switch we recommend to use it in a switch-board with earth-bonding distri-
bution frame for grounding of the power supply, of the switch, the data cables and the antenna.
