orientAtion
OPECL modules must be affixed to a solid, non-vibrating
structure capable of supporting a minimum of 100 lbs (46
kg), located within the system’s rated separation distance.
See examples below.
In all cases, the maximum movement of the supporting
structure under all anticipated operating conditions must
be no more than ±0.25 degrees. When using a vertical
post, the post should be absolutely stable and without
vibration. Generally, when the post is set into the ground,
the portion below grade should be set in concrete at least
1 meter deep.
