5. Installation
5.1
Visual check
After receipt, the unit has to be checked for signs of physical
damage. If any damage can be found, the unit may not be
operated. Also contact your dealer immediately.
5.2
Mains connection
The mains connection is done with the included mains
cord.
The plug is a 10A mains plug after IEC 20. The mains
cord has a length of about 1.5m and a cross section of x
0.75mm².
The unit is fused with a 5 x 20mm safety fuse (T2.5A), which
is accessible at the rear side

Terminal DC input
The load input is located at the rear side of the device. The
connection to any feeding source is done here by the screws.
Always take care for correct polarity! Only DC voltages
allowed!
The input is not fused. In order to prevent damages by the
feeding source always observe the nominal values of the
electronic load! If necessary, install an extra fuse between
load and source, especially when discharging batteries.
The cross section of the load cables depend on the current
input. We recommend to use:
at 150A:
2 x 16mm² or at least 1 x 50mm²
at 300A:
2 x 50mm² or at least 1 x 150mm²
0,825
at 600A:
2 x 150mm² at least
per cable (flexible wire).
The inputs "+" und "-" are not grounded, so that one of them
may be grounded, if necessary.
Attention! When grounding one of the input poles al-
ways check if one of the output poles of the source (eg.
power supply) is also grounded. This could result in a
short-circuit!
Attention! Notice the potential shift of the input poles
when using series connection! Grounding is hereby
only recommended at the pole with the lowest potential
against ground.

Terminal System Bus
The terminal System Bus (rear side) is another interface
0,8
with important features. For pin assignment and detailed
description see section „6.10 Functions of the terminal
System Bus".
5.5
Using and connecting the remote sense
The remote sense feature is wired at terminal System Bus.
See section „6.10 Functions of the terminal System Bus" for
more information.
In order to compensate voltage drops over the load cables
(max. 1.1V per line) between feeding source and consumer,
the load can measure the voltage at the source via the
remote sense input poles at the terminal System Bus and
regulates accordingly. The connection is done, with correct
polarity, at the rear side of the device at the terminal System
Bus, at pin 1 (+ Sense) and pin 4 (–Sense). Recommended
cross section: 0,2mm
0,5
sleeves.
!
(+) Sense must only be connected to (+) output
and (–) Sense must only be connected to (–) out-
put of the feeding source. Else both device might
get damaged.

Interface card slot
The unit can be equipped with an optional interface card.
The slot to insert the card is located at the rear side. Further
information about the interface cards can be found in section
