Wiring

• This equipment is designed to operate only at SELV/PELV/Class 2/Limited Power environments.
• All power supplies in the system must include double insulation. Power supply outputs must be rated as SELV/PELV/Class 2/Limited Power.
• Do not connect either the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to device’s 0V point.
• Do not touch live wires.
• All wiring activities should be performed while power is OFF.
• Use over-current protection, such as a fuse or circuit breaker, to avoid excessive currents into the Uni-I/O™ module supply port.
• Unused points should not be connected (unless otherwise specified). Ignoring this directive may damage the device.
•  Double-check all wiring before turning on the power supply.

Caution

• To avoid damaging the wire, use a maximum torque of 0.5 N·m (5 kgf·cm).
• Do not use tin, solder, or any substance on stripped wire that might cause the wire strand to break.
• Install at maximum distance from high-voltage cables and power equipment.

Wiring Procedure
Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm2 –3.31 mm2).

1. Strip the wire to a length of 7±0.5mm (0.250–0.300 inches).
2. Unscrew the terminal to its widest position before inserting a wire.
3. Insert the wire completely into the terminal to ensure a proper connection.
4. Tighten enough to keep the wire from pulling free.

Uni-I/O™ Module Connection Points
All wiring diagrams and instructions in this document refer to the I/O connection points of the different modules. These are arranged in four groups of seven points each, as shown in the figures below.

Wiring Guidelines
In order to ensure that the device will operate properly and to avoid electromagnetic interference:

• Use a metal cabinet. Make sure the cabinet and its doors are properly earthed.

• Use wires that are properly sized for the load.

• Route each I/O signal with its own dedicated common wire. Connect common wires at their respective common (CM) points at the I/O module.

• Individually connect each 0V point in the system to the power supply 0V terminal.

• Individually connect each functional earth point ( ) to the earth of the system
  (preferably to the metal cabinet chassis). Use the shortest and thickest wires possible: less than 1m (3.3’) in length, minimum thickness 14 AWG (2 mm2).

• Connect the power supply 0V to the earth of the system.

NOTE: For detailed information, refer to the document System Wiring Guidelines, located in the Technical Library in the Unitronics’ website.
