3.1.2.5 Installation and Wiring
Installation of the DIN rail
1.
The ELC may be secured to a cabinet by using 35mm in height and 7.5mm in depth DIN
rail. When mounting the ELC to 35mm DIN rail, be sure to use the retaining clip to stop any
side-to-side movement of the ELC and reduce the chance of wires coming loose. The
retaining clip is at the bottom of the ELC. To secure the ELC to DIN rail, pull down the clip,
place it onto the rail and push it up to lock it in place. To remove the ELC, pull the retaining
clip down with a flat screwdriver and remove the ELC from DIN rail.
2. Install the ELC in an enclosure with sufficient space around it to allow heat dissipation, as
shown in the figure below.
Wiring
1.
Use 22-16 AWG (1.5mm) single-core wire or the multi-core wire for the I/O wiring. The
specification of the terminal is shown in the figure below on the right hand side. The ELC
terminal screws should be tightened to 1.95 kg-cm (1.7 in-lbs). Also, use 60/75°C copper
conductor only.
2.
I/O signal wires and power supply wires should not run through the same multi-wire
cable or conduit.
