It is notnecessary to detach the whole board for the grounding of the bus cable shield. Just detach theterminal block.4.4.1 Grounding by clamping the cable to the converter frameThis manner of grounding is the most effective and especially recommended when the distancesbetween the devices are relatively short (see 4.4.2.1).In this manner of grounding, the position of jumper X1 is of no importanceFigure 4-3. Grounding by clamping the cable to the converter frame1 Strip about 5 cm of the CanOpen cable in the same way as shown in Figure 4-4 but cut off thegrey cable shield.Remember to do this for both bus cables (except for the last device).2 Leave no more than 1 cm of the data cable outside the terminal block and strip the data cables atabout 0.5 cm to fit in the terminals. See Figures 4-5 and 4-6.Note: Do this for both bus cabels3 Insert the data cables of both CanOpen cables into terminals #2 and #4. See Figure 4-7.4 Strip the CanOpen cable at such a distance from the terminal that you can fix it to the frame withthe grounding clamp. See Figure 4-4.Error!
