5.2.4.1 Electrical insulation of the outputs
In standard cases, all negative poles of the outputs are electrically
connected to the motherboard.
For special applications, i.e. switching a positive pole, each output
can be electrically separated from the motherboard and from the
other outputs.
CAUTION!
Reduced battery life
Activation of electrical isolation of outputs reduces
battery life when operating the battery.
It is then impossible to give a reliable prediction of the
remaining battery life.
An electrically-insulated output only requires electricity if
the output is active (switched-on). You can therefore
minimize the negative influence of an electrically-
insulated output on the battery life by setting the pulse
duration to the lowest possible value when using it as a
pulse output.
The configuration software "enSuite" is suitable for this
purpose.
The electrical insulation of the outputs is not an approved
electrical isolation in accordance with ATEX. An
approved Ex-isolator is required when using the device
as associated apparatus in Ex zone 0 or 1.
In order to activate the electrical insulation of an output, move the
switch lever behind the corresponding output terminal away from the
terminal:
