General guidelines
Note the following guidelines for installing and wiring your LOGO!:
● Always ensure that the wiring of your LOGO! is compliant with current rules and
● Always ensure that the wiring of your LOGO! is compliant with current rules and
standards. Also, conform with all national and regional regulations when you install and
operate the devices. For information on standards and regulations that apply to your
specific case, contact your local authorities.
● Always switch off power before you wire or install/remove a module.
● Always use cables with appropriate conductor cross-sections for the relevant current. You

.
● Do not exceed the screw torque of the terminals. Range of torques: 0.5 Nm to 0.6 Nm.
● Keep the cabling as short as possible. If longer cables are necessary, use shielded
● Keep the cabling as short as possible. If longer cables are necessary, use shielded
versions. Always route your cables in pairs; that it, one neutral conductor plus one phase
conductor or signal line.
● Always keep separate:
– The AC wiring
– High-voltage DC circuits with high-frequency switching cycles
– Low-voltage signal wiring
– High-voltage DC circuits with high-frequency switching cycles
– Low-voltage signal wiring
● Install wires with appropriate strain relief.
● Provide a suitable lightning surge arrester for cables installed in hazardous areas.
● Do not connect an external power supply in parallel to the output load of a DC output.
● Provide a suitable lightning surge arrester for cables installed in hazardous areas.
● Do not connect an external power supply in parallel to the output load of a DC output.
This could develop a reverse current at the output if you have not installed a diode or
similar barrier device.
● Be sure to use only certified components to ensure reliable functioning of equipment.
