2.9 Installation of communication modules
In order to avoid interferences and shading effects, minimum clearances have to be considered
for the communication module.
Minimum clearance to metal parts: refer to fig. 2.5.
Minimum clearance between communication modules: refer to fig. 2.6.
Furthermore, the communication modules must have a minimum clearance of 25 mm to primary
loop cables in order not to expose them to too strong electromagnetic fields.
The mentioned minimum clearances only guarantee reliable energy supply, if the rotating
electromagnetic field can reach the wireless proximity switch in at least one direction, i.e. if the
wireless proximity switch is not shielded by metal parts or electrically conductive ring
constructions.
