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

5.3 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

50A:

2 x 4mm² or at least 1 x 10mm²

100A:

2 x 10mm² or at least 1 x 5mm²

200A:

2 x 5mm² or at least 1 x 95mm²

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.

5.4 Terminal System Bus

The terminal

System Bus (rear side) is another interface

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

– 2,5mm

flexible wire with cable end

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.

5.6 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
