6 Mounting and installation
Warning
Electric voltage!
Direct or indirect contact with live components can cause dangerous
currents to flow through the body, which may result in electric shock,
burns or even death.
- Always disconnect the main power supply prior to installation and/or
disassembly.
- Work on the 110 V - 240 V supply system must be performed only
by qualified personnel.
6.1 Requirements for the electrician
Warning
Electric voltage!
Install the device only if you have the necessary qualifications.
- Incorrect installation endangers your life and that of the user of the
electrical system.
- Incorrect installation can cause serious damage to property, e.g.,
due to fire.
The minimum necessary expert knowledge and requirements for the
installation are as follows:
- Apply the "five safety rules" (DIN VDE 0105, EN 50110):
1. Disconnect from power.
2. Secure against being re-connected.
3. Ensure there is no voltage.
4. Connect to earth.
5. Cover or barricade adjacent live parts.
- Wear suitable personal protective clothing.
- Use only suitable tools and measuring devices.
- Check the type of supply network (TN system, IT system, TT
system) to secure the following power supply conditions (classic
connection to ground, protective earthing, necessary additional
measures, etc.).
6.2 General installation instructions
- Terminate all branches of the wiring system via a connected bus device (e.g., indoor station, outdoor station, system device).
- Do not install the system controller directly next to the bell transformer or other power supplies (to avoid interference).
- Do not install the wires of the system bus together with 100 V - 240 V wires.
- Do not use common cables for the connecting wires of the door openers and wires of the system bus.
- Avoid bridges between different cable types.
- Use only two wires for the system bus in a four-core or multi-core cable.
- When looping, never install the incoming and outgoing bus inside the same cable.
- Never install the internal and external bus inside the same cable.
