2.3 Residual risks
Automatic Controls
The Ridder control-units are usually used in automatic controlled systems. Persons who do work
or stay near the system must know about that. If persons or their clothes touch the system during
operation, it can be dangerous.
Forces
Because of the forces in the systems (in which the control unit is installed), Ridder cannot be sure
that there will be no injury to persons or damage to the system.
