DIN Rail Installation

Grounding Function

The DIN rail must be attached to a conductive backplane that itself is connected to a protective ground (PE).

In the mounting channel of each piece of the TM5 equipment is a metal spring contact. When properly mounted on a metal DIN rail, these contacts provide connection to the functional ground (FE) for the entire TM5 System.

Mounting the DIN Rail

The TM5 System components are designed for mounting on rail conforming to IEC 60715.

To help achieve the stated TM5 System performance characteristics, the mounting hardware must be installed at the end positions and at 100 mm (3.94 in.) maximum increments along the length of the rail.

 WARNING
UNINTENDED EQUIPMENT OPERATION
  • Verify that the DIN rail is securely installed with mounting hardware at the end positions and at 100 mm (3.94 in.) maximum increments along the length of the rail.
  • Be sure that the DIN rail is firmly connected to a conductive backplane, and that the conductive backplane is secured to a protective ground as specified in this guide and in accordance with local regulations.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

The following figure illustrates the mounting requirements for the DIN rail:

Low profile NSYSDR200D DIN rail may be used with low profile mounting hardware such as flat head screws with countersunk mounting holes.

NOTE: If you use NSYSDR200D DIN rail, ensure that the maximum fastener screw head protrusion does not exceed 1.0 mm (0.039 in.) above the inner surface of the DIN rail.
