0. BEFORE STARTING
The Vitrum system that you have purchased is designed for connection to your existing
240V 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.
