SMA America, LLC 5 Connection 5.2 Cable Requirements and Information on Routing The cable length and quality have an effect on the signal strength in the Speedwire network. Observe the following cable requirements and the information on laying them. Disturbance in data transmission due to AC cables If unshielded power cables are used, they generate an electromagnetic field during operation which may induce interference in network cables during data transmission.
5 Connection SMA America, LLC 5.3 Connecting the Cable to the Communication Terminal Observe local regulations All electrical installations must be carried out in accordance with the electrical standards applicable on site and the National Electrical Code® (NE, ANSI/NFPA 70). Installations in Canada must comply with the applicable Canadian standards. Figures in this section All the steps in this section are supported by figures of the inverter types SB 3000US, SB 3800US and SB 4000US.
SMA America, LLC 5 Connection 4. If no conduit is to be used, proceed as follows: • Unscrew the counter nut of the cable gland. • Push the sealing ring onto the adapter. • Attach the cable gland to the enclosure opening using the counter nut. Ensure that the grooved side of the counter nut is facing the inverter enclosure. • Gauge the length from the communication terminal to the counter nut on the cable gland with the cable, and mark the position on the cable.
5 Connection SMA America, LLC • Unscrew the swivel nut of the cable gland but do not remove it. • Gradually guide the end of the cable through the cable gland into the inverter, until you can hear the shield clamp grip onto the cable shield. • Tighten the swivel nut of the cable gland. This will prevent the cable from slipping and the contact between shield clamp and cable shield being lost. 5. At the cable end, remove 1 1⁄2 in. (40 mm) from the cable sheath and the cable shield.
SMA America, LLC 5 Connection 9. Danger to life due to electric shock in case of incorrect cable insulation In case of incorrect cable insulation, high voltages may occur on the cable outside the inverter. • Guide the cable in the inverter through the insulating hose. The insulating hose must completely cover the cable and the conductors inside the inverter enclosure. • Cut the insulating hose to the required length, as necessary.
5 Connection SMA America, LLC 12. Attach an RJ45 connector to the other end of the cable (see manufacturer's manual). Observe the contact pin assignment of the network cable, as follows: Network cable Signal Contact pin RJ45 plug EIA/TIA 568A (8-conductor) Conductor color EIA/TIA 568B (8-conductor) Conductor color Profinet (4-conductor) Conductor color TD+ 1 white/green white/orange yellow TD- 2 green orange orange RD+ 3 white/orange white/green white RD- 6 orange green blue 13.
