We recommend using one Surge-Zapper at each serial device, for improved surge protection to the
Console at a gasoline outlet. This will effectively protect from static discharges via the serial
cable to earth, thus ensuring that the console computer equipment is fully guarded against spikes.
The unit is connected to protect a 9 way serial link all 8 wires are each individually surge protected,
wire number 9 is ground (earthing). All eight wires are fully protected.
The green wire must be attached to a very good ground (earth) source for the protection to work.
This may require the addition of an earth spike driven into soft ground, preferably near a dampened area
for best results.
Do not connect nor remove a Surge-Zapper with the system live. You must "power-down" both ends.
Warranty is limited to replacement of unit if it proves to be faulty. As with all lightning protection
devices, we do not guarantee it will stop major lightning hits, a strike of over 1 Million volts would be
patently obvious, however it will absorb the impact of localized static and spikes and ground EMF.
Direct hits by lightning cannot be fully protected by any means what-so-ever, if you really know how,
then please let us know !
Lightning tends to go where ever it wants, however, by creating a path by which it can easily travel to
ground as it is expressed, the path of least resistance, via the SurgeZapper, we feel this will do the
job as required.
The 12 months warranty on Surge-Zapper cover defects in assembly or manufacturing only.
Note: In the event of a large spike, the Surge Zapper may destroy itself in absorbing the impact of
a spike. We can replace the spent parts with new ones (at your expense) the surge zapper has done
its job. After a spike, Please return the SurgeZapper device for testing and rebuilding at a moderate
economical price.
