5 Installing DNT2Mi

This chapter provides instructions on how to mechanically install and connect DNT2Mi. The menu settings required for bringing the unit into use can be found in Chapter 6.

5.1Electromagnetic compatibility

DNT2Mi complies with EMC specifications (refer to Chapter 10) when the following conditions are fulfilled:

•The securing screws of the multiport DNT2Mi cover are properly fastened.

•All multiport DNT2Mi ports are provided with adapters, or unused ports provided with dummy plates.

•The DTE cables and connectors are provided with reliable shielding.

•The connector’s connecting screws are properly fastened, so that shielding integrity from the metal housing of the equipment to the cable shield over the interconnecting interface is secured.

•A grounded 3-conductor mains cord and a grounded mains outlet for mains-powered DNT2Mi terminals, or a similar grounding for DC- powered versions, is used.

5.2Grounding of DNT2Mi

The AC-powered version of DNT2Mi is grounded properly when the mains cord is connected to a grounded mains outlet.

The DC-powered version of DNT2Mi has a separate pin reserved for the ground connection, refer to Section 5.8.
