Connection points
Every cabinet has bus bars on the DC input, which have 3 or 6 connection points on their lower end. Each con-
nection point can be used to screw one or two cables. The table in section
lists the number and size of the
connection points for every rated input current and power. The connection points as seen from the side:
6x M10 for up to 12 cables
3x M8 for up to 6 cables
Connection example for two cables on one connection point with M10 ring lugs for 150 mm² cables:
The included cover for the DC input bars must always be installed when operating the cabinet,
no matter if the rear door is closed or not!
The copper bars can become very hot, especially with models rated for high currents. This is
mostly due the bars being positioned in the warm or hot stream of air exhausted on the rear
of the units. This heat submits to the DC cables and can lead to damage or even dissolution
of the sheathing. It’s thus recommend to use cables with higher temperature capability, such
as ones for 105°C.
