1. Introduction
The MILLENIUM II+ series has been designed for use in the household goods, medical and industrial fields. Each
module allows you to manage all the sensors and actuators in the installation. A display on the front panel allows
you to check the status of your system at any time.
The MILLENIUM II+ series features:
• Simple programming and parameter setting
• WINDOWS-based programming software
• Compact size
• EEPROM module backup
• Real-time clock as standard
• Output with high switching capacity
The MILLENIUM II+ series is ideal for simple automation systems (examples: lighting, air conditioning, irrigation,
doors, barriers, simple systems, greenhouses, ventilation). The real-time clock is used for time-based programming
of the units.

3.4 Mounting notes
The MILLENIUM II+ series can be installed in any location, but the following points should be
taken into consideration:
- Do not install the unit in an environment that is excessively dusty, conductive, corrosive, gas-
filled, damp, rainy or inflammable, or where there is excessive heat*, excessive shock or
vibration.
- Do not install the module in water or near any possible leaks.
- Protect the module from external debris during installation.
Keep as far away as possible from power cables and equipment. The MILLENIUM II+ series module can be installed
in enclosures complying with standard DIN 43880.
* To ensure adequate module ventilation, there should be a gap of 10 mm between the front panel and the
enclosure door, and also between the back of the enclosure and the back of the module.

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 mm²- 2.5 mm² (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.
