Initially, use the original cabling from the supplier primarily. • Use shielded cables for RS232 communication. • Use twisted pair and shielded cabling for RS422 and RS485. • Use the cabling intended for the bus type; Ethernet, Profibus, CC-Link, CAN, Device Net etc. • Install and connect according to applicable specifications for the relevant bus standard. • Use shielded cabling for Ethernet, preferably with foil + braided shield. • D-sub covers should be shielded, and the shield should be connected to the cover 360 ° where the cable comes in. Section 7 Additional Installation Tips To Achieve Better EMC Protection 3BSE043449R501 47 • Connect the shield at both ends. With longer distances, there is a risk that the ground potential may be different. In that case, the shield should only be connected at one end. A good alternative is to connect the other end of the shield to the ground via a 0.1 uF/250 V plastic capacitor. Both ends are then connected to the ground in terms of HF, but only connected to the ground at one end in terms of LF, thus avoiding the 50 Hz grounding loops. • Use an EMC cable gland or regular plastic cable gland, remove the outer jacket and connect the shield to the installation plate with a 360 ° metal cable clamp. 5352 Shielded cable Ground plane 1 Ground plane 2 Ground plate Ground plate in another building 0.1 uF/250 V Not same potential 5353 Metal cabinet Metal cabinet Terminal or connector Terminal or connector EMC cable gland Plastic cable gland Shielded cable Shielded cable Cable clamp in steel Short distance Ambient Temperature Section 7 Additional Installation Tips 48 3BSE043449R501 • Place the 24 V DC and communications cabling in one cable trunk/cable duct and 230/380 V AC in another. If the cables need to be crossed, cross them at 90 ° only. Avoid combining the cabling for stronger 24 V DC outputs with the communication cabling. • Ferrite cores that are snapped onto the shielded cabling may remove minor disturbances. Large ferrite pieces that are snapped onto unshielded cabling and where the wires go 2-4 times around the cores are approximately 5-25 times more efficient. Ambient Temperature The maximum ambient temperature for the operator panel is provided in the specifications. The ambient temperature refers to the temperature in the device cabinet which cools the panel’s electronics. 5354 Top 50° inside Middle 45° inside Bottom 40° inside Operator panel 30°C outside Power Power Power Airflow Axial fan 120x120 mm Section 7 Additional Installation Tips Ambient Temperature 3BSE043449R501 49 In most cases, the ambient temperature for the operator panel is significantly higher than the device cabinet’s ambient temperature. If the cabinet is tall and there are a number of heat-generating devices, the temperature at the top of the cabinet will be considerably higher than the theoretical temperature increase that would be expected. All electronics are sensitive to heat. The lifespan of an electrolytic capacitor is cut in half with an 8-10 °C increase in temperature. A 15-20 °C temperature increase results in a quarter of the lifespan etc. Rittal has a good program for estimating the anticipated average temperature in the cabinet as well as a large program for controlling the temperature in the device cabinet. An enamel-coated steel cabinet has a radiant heat value of 5.5 W/m2 and °C. Installing a fan inside the cabinet will even out the temperature, while moving air provides considerably better cooling than still air. A suitable fan is a 120 x 120 mm axial fan, available in 24 V DC, 115 a
