Bench Use
The handles on the front are for sliding in and out of the cabinet. Slots on the front plate are
provided for fixing the unit (rack-mount screws not included). The 6RL Series chassis is not
equipped with surface protection feet as it is intended primarily for 19” rack mount use. For
use on the bench, use protective sheet to prevent damage to tabletop surfaces.

Load Connections
5.10.1
Recommended Wire Size
The DC load output bus bars are located on the rear panel of the unit and not protected by
any fuses. The cross section of the DC load connection cables are determined by the
maximum current consumption, cable length and ambient temperature.
For cables up to 1.5 m/ 5 feet and average ambient temperature up to 50°C, the following
wire sizes are recommend:

Table 5-4: DC Load Wire Size Table
These values apply per connection pole for multi-conductor, insulated and openly
suspended – not inside conduit- cables. Single cables of, for example, 70 mm² may be
replaced by e.g. 2x35 mm² etc. For longer cables, the cross section dimensions must be
increased to avoid excessive voltage loss and overheating.
5.10.2
DC Terminal Types
The table below shows an overview of the various DC terminals. It is recommended that of
load cables connection always use flexible cables with properly sized ring lugs.
Type 1: Models up to 360 V output voltage
Type 2: Models from 500 V output voltage
M8 bolt on a metal rail
Recommendation: ring lug with a 8 mm hole
M6 bolt on a metal rail
Recommendation: ring lug with a 6 mm hole
