Connections to other Equipment
Surges can enter the wireless unit from connected devices, via I/O, serial or Ethernet connections. Other
data devices connected to the wireless unit should be well grounded to the same ground point as the
wireless unit.
Special care needs to be taken where the connected data device is remote from the wireless unit requiring
a long data cable. As the data device and the wireless unit cannot be connected to the same ground point,
different earth potentials can exist during surge conditions.
There is also the possibility of surge voltages being induced on long lengths of wire from nearby power
cables. Surge diverters can be fitted to the data cable to protect against surges entering the wireless unit.
The same principle applies to I/O device is not close to the wireless unit, the risk of surge increases. Surge
diverters for I/O wiring are available to protect the wireless unit.
