5.5.3 Connection conditions
All electrical terminals are connected to the ES11 by means of series isolating terminals.
The suitable conductor cross-sections for connecting the terminals are 0.2 to 2.5 mm
2
. To
achieve optimal electromagnetic compatibility it is recommended to use shielded cables for
connecting potentiometers or standardized active current or voltage signals.
Electromagnetic interference (EMI) on the actuating signal Y
I
or Y
U
can be
suppressed to a great extent by subsequently installing a filter to the actuating
signal input.
Please contact the manufacturer direct for technical information.
ATTENTION !
To facilitate use in 3-conductor technology, the ground input
may be connected
to the N contact of the power input only in the 24 V AC version.
The new contact is then referred to as zero potential (0V).
If installed in a 3-conductor technology with strong electromagnetic influence this
can lead to disturbances. In this case don‘t join the ground input
with the
mainfuse N.
Fuse protection of mains power supply on system side: 6 A max.
