Electrical Connections - Nice Neomat A Instrucciones Y Advertencias Para La Instalación Y El Uso

2.1) Electrical connections

CAUTION!
• In accordance with electric installation rules, on the power
line of the product install a disconnect device that ensures
complete disconnection from the grid in the overvoltage
category III conditions. This device is not supplied with the
product.
• Carefully follow all the connection instructions. An incorrect
connection may be dangerous and cause damage to the
system.
Green label
2.1.1) Mains power supply (Brown + Blue + Yellow/Green):
The mains power supply must be connected to the following wires: Brown (Phase); Blue (Neutral) and Yellow/Green (Earth).
Caution! – Do not connect the mains power supply (230V or 120V) to the other wires.
2.1.2) "Step-by-Step" input (White + Black/White):
To manually command the automation system, a simple button can be connected between the White wire (Step-by-Step input) and the
Black/White wire (Common).The operating method follows the sequence: up-stop-down-stop.
If the button is kept pressed for more than 3 seconds (but less than 10) an up manoeuvre is always carried out (corresponding to the s but-
ton on the transmitters). If the button is kept pressed for more than 10 seconds a down manoeuvre is always carried out (corresponding to
the, t button). This function can be used to "synchronise" multiple motors to carry out the same manoeuvre, regardless of their operating
status.
2.1.3) "TTBUS" input (White + Black/White):
"TTBUS" is a Bus that was developed to control individually motors or control units, up to 20 devices by simply connecting them in parallel
with just 2 wires. Further information is contained in the instructions for the remote controls via "TTBUS".
The TTP or TTI programmers can be connected to the TTBUS input making the system management and programming operations easier;
for further information, consult the related manuals.
Yellow label
The cable used for the electrical connections of the NEOMAT-SA,
NEOMAT-MA and NEOMAT-LA motors has 6 wires; 3 of the wires
(yellow tag) are for the mains power supply and 3 wires (green tag)
are for the command signals.
For the electrical connections see the diagram below.
