FAQs
Begin by confirming the enclosure height is at least 2000 mm. Position the PDU in the zero-U space between the side panel and the 482.6 mm mounting level. Connect using the fixed/CEE 3 m feed cable, ensure the IP20 protection is maintained, and secure the unit so all module slots align with the enclosure’s backplane. This reduces wiring complexity and accelerates commissioning.
Its design uses a PSM busbar in an aluminium, natural anodised section and a length of 1,695 mm, enabling vertical installation without occupying interior rack depth. The zero-U configuration minimizes clutter, improves airflow, and supports scalable power distribution with up to six module slots and a single infeeds connection.
The DK 7859.081 operates on 3~, with a maximum current of 16 A and supports one infeeds input. It features six module slots, a 3 m connection cable, and a fixed/CEE connection. The unit is rated IP20 and designed for operating temperatures from 5 °C to 45 °C with ambient humidity of 10–90% non-condensing.
Yes. The product is specified for enclosure height up to 2000 mm and is intended for 800 mm wide IT racks, matching standard VX IT configurations. Its modular PDU design and 1695 mm length ensure a precise fit, simplifying installation and standardizing power distribution across cabinets.
The modular PDU reduces wiring complexity, enabling faster deployment and easier future reconfigurations. Its robust aluminium construction and IP20 protection minimize corrosion and environmental exposure. With six module slots and a 3 m feed, you gain scalable capacity without replacing the entire assembly, delivering lower lifecycle costs and improved reliability.
