Electrical installation

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 to EN 60204-1 for the electric
logic supply.
Also observe the general requirements for PELV power circuits to EN 60204-1.
Only use power sources which guarantee reliable electrical isolation of the operating
voltage 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 require
ments). 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.
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.).
