Short-circuit protection
The doorbell transformer features electronic cut-off in the event of a short circuit, an overload in the secondary circuit, no-load operation, or overtemperature. Once the fault is resolved, the device automatically returns to safe operating mode.


Important installation notes
The device complies with Directive 2004/108/EC on electromagnetic compatibility and the Low Voltage Directive 2006/95/EC.

• Before installation and maintenance work, disconnect the mains supply and secure it against accidental reconnection.
• Connection: Mount the doorbell transformer on the DIN rail inside the distribution board. Connect the power supply L and N to the two lower 230-V terminals. Connect the two doorbell wires to the desired (8 / 12 or 24 V) terminals of the doorbell transformer.
• The doorbell transformer is designed for short-term loads.
• The device is suitable for indoor use only. Protect the device from excessive heat.
• The load specified on the device must never be exceeded or fallen short of.
• Dangerous voltages are present inside the device; the housing is there for safety and must not be opened. There are no user-serviceable parts inside the housing.
• If the device is used for purposes other than those specified, or connected incorrectly, no liability/warranty will be assumed for any resulting damage.
• Steps before switching back on: Remove tools and equipment. Leave the danger area. Remove the short-circuiting and earthing first at the work location, then at the remaining locations. Lift the earthing cable first from the plant components, then from the ground. Plant components and lines without an earthing cable (if previously present) must no longer be touched. Reattach any removed protective covers and safety signs. Only lift protective measures at the switching points once clearance has been confirmed from the work locations.
