Connection 6
6.1 Overview of connection
Ensure that the installation complies with the following conditions:
• The device may only be connected to 24 VDC power supply systems which
meet the requirements of a safe extra-low voltage with protective separation
according to SELV. The conductor cross-section selected must be large
enough so that if there is a short circuit in the SICLOCK TC100 no damage
can be caused by an overheated cable. For the conductor cross-section, see
Connecting the power supply (Chapter 6.2).
• Avoid extreme ambient conditions as far as possible.
• Protect the device against dust, moisture, heat and severe vibrations.
• Do not place the device in direct sunlight.
• Install the device in such a way that it cannot pose any danger, for example by
falling down.
• Do not cover the ventilation slots
• Permissible mounting position (Chapter 4.4.2).
