The terminal strips of the logic unit SRL 63-a are electrically live during operation!
Because of the electrical currents which may flow, serious injuries are possible!
Before working on the terminal strips (assembly, disassembly, connecting the cables), al-
ways ensure that the unit is de-energized!
An external voltage is present at terminal strips X 1 (terminals 16 to 20) and X3 (ter-
minals 1 to 5).
