5.2
Electrical installation
5.2.1
Safety instructions
During installation, the requirements of EN 60204-1 must be fulfilled.
Warning
Danger of electric shock in case of voltage sources without safety measures.
Use only PELV (protective extra-low voltage) circuits according to EN 60204-1 for the
electric logic supply.
Also observe the general requirements for PELV power circuits according to EN
60204-1
.
Only use power sources which guarantee reliable electrical isolation of the
operating voltage according to EN 60204-1.
Protection against electric shock (protection against direct and indirect contact) is
guaranteed in accordance with EN 60204-1 by using PELV circuits (electrical equipment of
machines, general requirements). The 24 V power supply unit used in the system must
satisfy the requirements of EN 60204-1 for DC power supply (behaviour during power
interruptions, etc.).
The cable is connected via a plug, making it easier to replace the safety module.
Make sure that no jumpers or the like can be inserted parallel to the safety wiring,
e.g. through the use of the maximum wire cross section of 1.5 mm² or suitable wire
end sleeves with insulating collars.
Use twin wire end sleeves for looping through lines between neighbouring devices.
5.2.2
ESD protection
With non-assigned plug connectors, there is a danger of the device that other parts of the
system may be damaged as a result of ESD (electrostatic discharge). Earth the system parts
prior to installation and use suitable ESD equipment (e.g. shoes, earthing straps, etc.).
5.2.3
Connection [X40]
The SE-Power FS Safety Module STO has a combined interface for control and
acknowledgment via the plug connector [X40].
