Frame grounding
The ELECYLINDER has a built-in controller circuit board.
The controller frame grounding line is connected to the ELECYLINDER body
and through to ground via the ELECYLINDER mounting surface.
If not grounding through the mounting surface, there are fixing screws (2 locations) under the
end cover, of which either one can be used for the ground wire connection.
Use a tester to measure the continuity between the fixing screws and grounding surface to
check whether it is grounded or not.
Conduction can be checked in the area on the base bottom where no paint is applied.
