System manual CECX / Safety notes
!
WARNING!
ï‚· All parts of the system that must be supplied with a voltage higher than
safety extra-low voltage (SELV according to EN 61131-2) and has
touchable metal parts, must be earthed. Otherwise, the series con-
nected protection devices are ineffective.
2.2.1.1 Safety extra-low voltage
!
WARNING!
Danger of personal injury due to electric shock!
ï‚· Supply the KEBA control exclusively from power sources that have a
protective low voltage (e.g. SELV or PELV according to EN 61131-2)
ï‚· Connect only voltages and power circuits to connections, terminals
and interfaces up to 50 V rated voltage that have a secure disconnect
for hazardous voltages (e.g. with sufficient isolation and voltage-
proof).
2.3 Safety instructions for programming
!
ATTENTION!
ï‚· The instructions contained in these manuals must be precisely fol-
lowed in all circumstances. Failure to do so could result in the creation
of potential sources of danger or the disabling of safety features inte-
grated in the CECX modular control system.
ï‚· Apart from the safety instructions given in these manuals, the safety
precautions and accident prevention measures appropriate to the situ-
ation in question must also be observed.
ï‚· Measures must be taken to ensure that in the event of power dips or
power failures, an interrupted program can be properly restarted. In
such situations, no dangerous operating conditions must be allowed to
occur even temporarily.
ï‚· In all situations where faults occurring on the automation system could
cause personal injury or significant damage to machinery and equip-
ment, additional external safety measures must be taken in order to
ensure the system as a whole remains in a safe operating condition
even in the event of a fault.
