Mounting the antenna

CAUTION!

Danger to life from electromagnetic fields

To adhere to the limit values for people's exposure to electromagnetic fields,
it is necessary to mount the antenna at least 25 cm away from people.

Mounting the antenna directly on the device

To mount the antenna, proceed as follows:

1) Switch off devices connected to the KeContact M20 and disconnect their

power cables.

2) Tighten the antenna (

2

) at the antenna connection (

1

).

The antenna has been installed.

Mounting the antenna on the control cabinet

To mount the antenna, proceed as follows:

1) Switch off devices connected to the KeContact M20 and disconnect their

power cables.

2) Unscrew the locknut and remove it and the washer from the antenna.

3) Feed the antenna cable into the control cabinet through a predrilled hole

(for M10 screw).
