0. BEFORE STARTING
the Vitrum system that you have purchased is designed for connection to your
existing 230V power supply circuit. Before commencing installation, ensure that the
mains power supply had been disconnected by setting the main switch on your
electricity meter to
OFF
. Do not re-connect the power supply and start using Vitrum
until all connections have been correctly completed and the Vitrum unit has been
inserted into the wall-mounting box.
Vitrum must be installed by a professional electrician who is
qualified to operate on electrical power circuits in full compliance
with all current safety legislation.
For each device, connect the power supply and the return wire from the actuators
as shown in the circuit diagrams printed on the rear of the boxes in the vicinity of
the terminal block. Refer exclusively to the circuit diagrams contained in this manual,
especially if connecting the system without an earth wire.
Carefully check that the wires and connectors are securely fastened. After
securing the unit to the wall-mounting box, temporarily use the plastic cover
for protection until the glass décor plate is fitted.
Do not install Vitrum in the vicinity of sources of heat or in conditions of high humidity.
IMPORTANT:
Fit a rapid-acting fuse with a high switching capacity that is
suitable for the load applied to the device.
