Installation; Electrical Connections - Gewiss Chorus GW 90851 Manual Del Usuario

WARNING: the installation of the device must be exclusively done by
qualified personnel, following the regulations in force and the
guidelines for KNX installations.
1. The length of the bus line between the actuator and the power supply unit must not
exceed 350 metres.
2. The length of the bus line between the actuator and the most distant KNX device to
be controlled must not exceed 700 metres.
3. Do not create ring circuits so as to prevent undesirable signals and overloads.
4. Keep a distance of at least 4 mm between the individually insulated cables of the bus
line and those of the electric line (figure C).
5. Do not damage the electrical continuity conductor of the shielding (figure D).
WARNING: the unused bus signal cables and the electrical continuity
conductor must never touch elements under power or the earth conductor!
Assemble the Easy 2-channel shutter actuator 6 A on a 35mm DIN rail in the following
way (figure G):
1. Insert the upper coupling of the device in the DIN rail.
2. Turn the device and lock it on the DIN rail, using the fixing tab.
WARNING: cut off mains power before connecting the device to the
electricity mains!
Figure B shows the electrical connections diagram.
1. Connect the bus cable's red wire to the terminal's red connector (+) and the black
wire to the black connector (-). Up to 4 bus lines (wires of the same colour in the
same connector) can be connected to the terminal (figure E).
2. Insulate the screen, the electrical continuity conductor and the remaining white and
yellow wires of the bus cable (should a bus cable with 4 conductors be used), which
are not needed (figure D).
3. Insert the bus connector into the special feet of the device. The fastener guides
determine the direction it should be inserted. Insulate the bus terminal using the
relative cover, which must be screwed onto the device.
