ATTENTION: disconnect mains voltage before connecting the device to
the mains!
Figure B shows a diagram of the electrical connections.
1. Connect the red wire of the bus cable to the red terminal (+) of the terminal and the
black wire to the black terminal (-). Up to 4 bus lines can be connected to the bus
terminal (same coloured wires on the same terminal) (figure F ).
2. Insulate the shield, the electrical continuity conductor and the other white and yellow
wires of the bus cable (if a 4-conductor bus cable is being used), that are not
necessary (figure D).
3. Insert the bus terminal in the device's pins. The correct insertion direction is determined
by the fixing guides. Insulate the bus terminal with the cover to be screwed onto the
device.
The cover guarantees the minimum separation distance of 4mm between the power
cables and the bus cables (figure G ).
4. Connect the loads to the relevant supplied screw terminals, making sure the current
limits specified in the Technical Data are not exceeded. Insert the terminals in the
actuator output connectors, and check they are correctly inserted (figure H).
Using the local command push-button
With the local command push-buttons (figure A) you can control cyclic ON/OFF switching
over, reversing the status of the relay each time it is pressed (default setting).
If a priority command is active, the local commands will not be executed.
It is possible to configure the behaviour of the local command push-button via ETS
ATTENTION: the local command push-buttons will only work if BUS voltage
is present.
The device does not require any maintenance. Use a dry cloth if cleaning is required.
