Spanners or tools should never be used to tighten the connectors. They should only
ever be finger tight.
10.16.1
Temperature
Spatial FOG should not be subjected to temperature's outside of it's operating range.
Subjecting Spatial FOG to temperature's outside of the storage range can cause failure
of the system.
10.16.2
Water
Spatial FOG is water-proof to the IP68 standard which means that it can be submersed
in water to a depth of up to 2 metres only. Submersion to depths beyond 2 metres can
cause water entry and destruction of the internal electronics.
10.16.3
Salt
Spatial FOG is made from marine grade aluminium which gives it reasonably good salt
water corrosion resistance. However Spatial FOG cannot tolerate extended periods of
time in salt water environments. After any contact with salt water environments,
Spatial FOG should be thoroughly rinsed with fresh water.
10.16.4
Dirt and Dust
Spatial FOG is completely sealed against dirt and dust entry. It is important to note
that this is only the case when the connectors are mated. When un-mating the
connectors if the Spatial FOG unit is dirty or dusty, the dirt should be rinsed of with
fresh water first and then dried of. This is to prevent dirt or dust entering the
connectors which can cause them to fail.
10.16.5
PH Level
Environments with a high or low PH level can cause the Spatial FOG enclosure to
corrode. If Spatial FOG comes into contact with these environments it should be rinsed
in fresh water as soon as possible. It is not recommended to operate Spatial FOG in
non neutral PH environments.
10.16.6
Shocks
Spatial FOG can tolerate shocks to 25g, however continuous shocks of this severity are
likely to cause premature failure. Shocks above 25g can efect the factory sensor
calibration and degrade performance. Normally shocks to Spatial FOG when mounted
in a vehicle are fine. Even a high speed car crash is likely to reach a peak of only 50g.
Shocks directly to Spatial FOG's enclosure can more easily go over the limit however
so care should be taken when handling the unit prior to mounting.
