Mount Antenna

The 750-644 I/O module has an SMA socket for attaching an external antenna.
1. Mount the respective antenna based on your method for mounting.
Set up lightning protection when using an external antenna!
When using an external antenna located outside the building, appropriate
measures must be taken to protect against lightning.
Installation instructions when using antenna 758-912
Antenna 758-912 may be used in an environment that meets the IP20 degree of
protection. The integrated magnetic base can be used to secure it to a suitable
metallic surface. The surface selected should be level in a radius of min. 12 cm
around the place of installation. The absence of such a reference surface can
negatively affect transmission and reception.
2. Then lay the connecting cable of the antenna and note the bend radius. If
external forces can act on the connecting cable: Make sure there is adequate
strain relief.
3. Then attach the connecting cable to the SMA socket of the 750-644 I/O
module.
