NOTICE
Argus 16S DCS/24S DCS:
The string monitoring box is equipped with blue spring-type terminals for connecting the negative
DC string leads. The maximum cross-section for leads to be connected to these spring-type termi-
nals is 16 mm². The length of insulation to be stripped off is 18-20 mm. Use an operating tool with
a partially stripped shaft, type 2, blade 3.5 mm x 0.5 mm.
Powador Argus 16S DCS FR/24S DCS FR:
The string monitoring box is equipped with grey fuse holders for connecting the positive DC string
leads. The maximum cross-section for leads to be connected to these fuse holders is 10 mm². The
length of insulation to be stripped off is 10-20 mm.
DANGER
Risk of fatal injury due to electric shock
The incorrect connection of the positive and negative DC connections can prevent an all-pole
disconnection of the DC connections. This can lead to overload and destroy the DC disconnects.
This may cause arcing, which poses a risk of serious injury and damage to the unit.
› Ensure that all poles of the PV generator are disconnected by checking the connection of the
DC inputs (see the following table).
