Wiring

|

• Do not touch live wires.

---|---
|

• This equipment is designed to operate only in 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 pin.
• 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 power supply connection point.
• 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

|

Wiring Procedure

Use crimp terminals for wiring;

• Controllers offering a terminal block with pitch of 5mm: 26-12 AWG wire (0.13 mm2  3.31 mm2 ).
• Controllers offering a terminal block with pitch of 3.81mm: 26-16 AWG wire (0.13 mm2 – 1.31 mm2 ).

1. Strip the wire to a length of 7±0.5mm (0.270–0.300“).
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.

Wiring Guidelines

• Use separate wiring ducts for each of the following groups:
  • Group 1: Low voltage I/O and supply lines, communication lines.
  • Group 2: High voltage Lines, Low voltage noisy lines like motor driver outputs. Separate these groups by at least 10cm (4″). If this is not possible, cross the ducts at a 90˚angle.
• For proper system operation, all 0V points in the system should be connected to the system 0V supply rail.
• Product-specific documentation must be fully read and understood before performing any wiring.
  Allow for voltage drop and noise interference with input lines used over an extended distance.
  Use wire that is properly sized for the load.

Earthing the product

To maximize system performance, avoid electromagnetic interference as follows:

• Use a metal cabinet.
• Connect the 0V and functional ground points (if exist) directly to the earth ground of the system.
• Use the shortest, less than 1m (3.3 ft.) and thickest, 2.08mm² (14AWG) min, wires possible

Panel-Mounting
For programmable controllers that can be mounted also on panel, in order to meet the UL Haz Loc standard, panel-mount this device on the flat surface of Type 1 or Type 4X enclosures

Communication and Removable Memory Storage
When products comprise either USB communication port, SD card slot, or both, neither the SD card slot nor the USB port are intended to be permanently connected, while the USB port is intended for programming only

Removing / Replacing the battery
When a product has been installed with a battery, do not remove or replace the battery unless the power has been switched off, or the area is known to be non-hazardous.
