Connection to DC sources (6U models)

Connecting a suitable DC source to a 6U model of this series is basically the same as with 3U models. The differ-
ences lie in the higher required cross section of cables and the connection point, which is important concerning
protection against physical contact.
For cables up to 5 m (16.4 ft) and average ambient temperature up to 50 °C (122 °F), we recommend:
up to 120 A: 35 mm²
up to 240 A: 95 mm²
up to 1020 A:
4 x 95 mm²
per connection pole (multi-conductor, insulated, openly suspended). Single cables of, for example, 70 mm² may
be replaced by 2 x 25 mm² etc. If the cables are long then the cross section must be increased to avoid voltage
loss and overheating.

Connection points

The default connection points on the DC input of 6U models are defined as shown below (red arrows). If more
than two cable per DC pole is going to be connected, the upper or lower screw connection points (terminal type
1) can also be used:
Models with DC terminal type 2
It is recommended to lay the cables in a way so they lead to the DC input vertically from below
or above. This shall make it possible to install the safety DC cover, which should be mounted
all the time, and to avoid the cables from being permanently positioned within the warm or hot
exhaust air stream at the rear of the load device.
