• For the connections use a VIMAR 01840.E sheathed and twisted pair (2x0.5 mm
2
, nominal insulation voltage 300/500 V). The wire pair distributes both the power supply
voltage (29 V d.c.) and the device control signals, and can be placed inside the same corrugated pipe that carries the electrical mains cables.
2.2
Bus length: general rules.
• Maximum length of the bus cable: 1000 m.
• Maximum distance between power supply and device: 350 m.
• Optimum position of each power supply: at the centre of the BUS line.
• Maximum distance between two devices: 700 m.
• Minimum distance between two power supplies: 40 m (loads must be balanced between the two power supplies).
It is important for the load to be well distributed between the two power supplies; the two power supplies should be placed at the ends of the one of the circuits of the system
that has the largest number of devices or branches.
• Optimum position of two power supplies: at the ends of the BUS line
• Minimum voltage on the furthest device: 23 V d.c. (at rest)
2.3
Putting the system into service.
1. Lay out the bus cable and connecting terminals, maintaining the correct polarities.
2. Lay out the cable for the electrical connections of the actuators.
3. Wire the control panel, components and power supply.
4. Power up the system.

WEEE - Information for users
If the crossed-out bin symbol appears on the equipment or packaging, this means the product must not be included with other general waste at the end of its working life. The user must take the worn product to a sorted
waste center, or return it to the retailer when purchasing a new one. Products for disposal can be consigned free of charge (without any new purchase obligation) to retailers with a sales area of at least 400 m
2
, if they measure
less than 25 cm. An efficient sorted waste collection for the environmentally friendly disposal of the used device, or its subsequent recycling, helps avoid the potential negative effects on the environment and people’s health,
and encourages the re-use and/or recycling of the construction materials.
