SMA-2500 or CSD-N-6000, should be fitted between the module and the antenna. If using non-WEIDMULLER
surge suppression devices, the devices must have a
“turn on” voltage of less than 90V. If the antenna is not
already shielded from lightning strike by an adjacent grounded structure, a lightning rod may be installed above
the antenna to provide shielding.

2.3 Power Supply
The WI-MOD-xxx-E-5W module can be powered from a 10
—30 Vdc supply. The supply should be rated in
accordance with the supply voltage and radio power level. The power requirements for the WI-MOD-xxx-E-5W unit
are shown in the table below.
The positive side of the supply must not be connected to ground. The supply negative is connected to the unit
case internally. The DC supply may be a floating supply or negatively grounded. A ground terminal is provided on
the back of the module. This terminal should be connected to the main ground point of the installation in order to
provide efficient surge protection for the module (refer to the installation diagram in the WI-MOD-xxx-E-5W
Installation Guide).
