Reference manual CAN-bus installations running at long distances and low speeds can use fairly long stub lines. This allows for a simpler wiring topology where the different nodes can be placed up to 5 meters away from the 'backbone'. Particularly on long distances, this is extra beneficial because the effective length of the CAN-bus can remain shorter, which saves on wiring cost and - more importantly - reduces voltage drops along the line. To aid such install, we have this field bus distribution box, which allows for up to 6 or 12 cable segments to be joined together. This is done with 5-pole...

Reference manual

Reference manual Mount the junction box on a flat surface with properly aligned holes. This prevents excessive stresses in the enclosure and reduces the risk of voiding the ingress protection rating. All M16x1.5 holes in the junction box shall be fitted with either a suitable cable-gland containing a cable, M12-style pluggable connection or M16 blanking plug. All of which shall be equipped with a matching sealing ring. If possible, only install the cables after the junction box has been mounted. At very least wait until the box has been mounted before tightening the cable glands. This reduces...

Reference manual Wire assembly Push down the lever with a flat tool. Then insert the wire fully so that the insulation is inserted into the hole. Release the lever to fix the wire. CAN-bus Termination and fuse The junction box contains a 120Ω termination resistor in series with a 40mA removable fuse. Note that the fuse has a faily high self-resistance of about 10Ω, so the effective termination resistance can be extepected to be around 130Ω. If no termination is needed, the fuse can be removed. When blown, the fuse must be replaced by same rating and voltage; 40mA/125V. Test points The testpoints...

Reference manual 4.6.2 Intrinsically safe circuits When used for intrinsically safe circuits, no exposed circuits with other protection are allowed inside the junction box. 4.6.3 Flexible cables Supplied cable glands are suitably only for fixed installation of cables. In case of flexible cables, for example for hand-held control pendants, the cable should be secured independently of the glands in the enclosure. 4.6.4 Pluggable M12 connection All connections shall be of female / socket type, except at most one which shall then be used as the power feed for all devices connected to the junction...
