Vivo Buri Power supply KNX 160/320/640mA Manual

Description

The Vivo® power supply Bil/Popi/Buri KNX is a KNX device for rail mounting which produces and monitors the 30 Vdc voltage required to operate the bus system. The device has an integrated choke which provides the decoupling between the power supply and the information on the bus line. On a KNX bus line can be connected up to 64 KNX bus devices. The output is protected from overload and short circuit. The device can support short interruptions of the mains voltage (max 200 ms).

Switching, display and connection elements

The device is equipped with a reset pushbutton, terminal blocks for mains voltage 230/110 Vac, KNX bus line.

Planning

Planning a KNX bus installation, the use of a 640 mA power supply unit requires to take into account the following guidelines:

• the maximum number of bus devices connected is 64;
• the maximum length of a line segment is 350 m
  

1. Terminal blocks for power supply 110-230 Vac 50/60 Hz
2. Status LED
3. Reset pushbutton (internal)
4. Terminal block for KNX bus line asured along the line between the power supply and the furthest bus device;

• the maximum distance between two bus devices cannot exceed 700 m;
• the maximum length of a bus line is 1000 m, keeping into account all segments.

At the same bus line can be connected not more than two power supplies. A second power supply may be necessary when the installation in distribution boards requires a particular concentration of the bus devices (tipically more than 30 units installed within 10 m). In this case a power supply has to be installed near the group of devices. Between two power supplies installed on the same bus line a minimum distance of 200 m is required, measured along the line.

Mounting

The device has degree of protection IP20, and is therefore suitable for use in dry interior rooms. The housing is made for rail mounting according to EN 60715 in boards or cabinets for electrical distribution. The installation is in horizontal position, the correct position is when the terminals for KNX bus line and auxiliary

In order to supply the KNX bus lines use only a KNX bus power supply (e.g. Vivo Cursa KNX). The use of other power supplies can compromise the communication and damage the devices connected to the bus.

output are located at the bottom and the terminals ( , L, N) for connecting the mains power supply 230/110 Vac are located at the top. For the installation of the device on the rail proceed as follows:

• with the aid of a tool bring the locking device in the fully lowered position (a);
• place the upper edge of the rear inner profile on the upper edge of the rail (b);
• rotate the device towards the rail (c);
• push the locking device upward until it stops (d).
  Before removing the device, be sure terminals for bus and have been extracted from his slots. Use a screwdriver to slide down the locking device and remove the device from the rail.

Electrical connections

Main supply 230/110 Vac
The connection to the 230/110 main supply Vac is made with screw terminals ( , L, N) located on the

Configuration and commissioning

Configuration
The device does not require any configuration with ETS^® (Engineering Tool Software) tool. The application software are available in order to add to an ETS project an Bil/Popi/Buri KNX power supply.

Commissioning
For the commissioning of the device turn on the mains power supply 230/110 Vac to which the device is connected. The green LED marked "ON" indicates the device operating.

The electrical connection of the device can be carried out only by qualified personnel. The incorrect installation may result in electric shock or fire. Before making the electrical connections, make sure the power supply has been turned off.

Reset

The device has a reset pushbutton. After a reset, the bus line is not powered for 20 seconds and the bus devices connected are restored to their original condition. During this interval of time the reset LED (red) is turned permanently on.
