EL 9000 B 15U/24U Series

2.3.5

Connection to DC sources

The DC input is located on the rear side of the cabinet and

is not

protected by any kind of fuse. The cross section

of the connection cables is determined by the DC current consumption, cable length and ambient temperature.
For cables

up to 5 m

of length and an average ambient temperature

up to 30°C

we recommend cross sections

per DC pole

(multi-conductor, insulated, openly suspended, standard cable) as listed in the table below. For lon-

ger cables or higher ambient temperatures the cross section must be increased accordingly in order to avoid high

voltage loss and overheating.
The cables are usually crimped with ring lugs and are tightened to the connection point at the lower end of the DC

bus bars. The mounting hole diameter of the ring lug should match the one of the connection point. This restricts

the number of applicable cable cross sections, for example because a M8 ring lug can take a max. of 95 mm² or

150 mm², depending on the manufacturer of the ring lug. The number of cables which are required increases when

using a smaller cross section per cable, but the cables also become better manageable.
