4. Connection
4.1 Connection notes
The MILLENIUM II
+
series has been designed to be easy to connect. A technician or engineer
trained in national and local electrical standards should be able to connect MILLENIUM II
+
series modules to the sensors and actuators without problem.
• The input and output cables should be in separate sheaths.
• Keep the I/O cables away from the power cables.
• Use the appropriate cables.
4.2 Conductor cross-section
For the I/O, use the following conductors: 0.14 mm
²
- 2.5 mm
²
(26 - 14 AWG).
Strip the conductor over a length of 7
±
0.5 mm.
Unscrew the terminal screw to its maximum before inserting the conductor.
Insert the wire fully into the terminal and screw tight to ensure correct connection.
Maximum tightening 0.5 Nm (5kgfcm).
Do not coat the conductors with tin to prevent them breaking.
4.3 Power supply
For an AC power supply, the phase should be connected to the "L" terminal and the
Neutral to the "N" terminal. Never connect the phase to the "N" terminal. The user could
receive a dangerous electric shock.
For a DC power supply, the positive conductor should be connected to the ‘+’ terminal and
the negative conductor to the ‘-’ terminal.
The power supply terminals should not be connected to the other module terminals.
