●
Maximum allowed inductance of 100 µH (2 twisted single strands, 75 m
long)

Parallel line routing where possible
The input 0V is connected in conductive form to the housing po‐
tential. It is therefore impossible to use an insulation monitor at
+24V and 0V against housing.

L+ L-, DC Bus Connection
Lethal electric shock caused by live parts with
more than 50 V!
WARNING
Before working on live parts: De-energize the installation and secure the power
switch against unintentional or unauthorized re-energization.
Wait at least 30 minutes after switching off the supply voltages to allow dis‐
charging. To shorten the waiting time until voltage has fallen below 50 V, you
can use a discharging device (see chapter "Appendix").
Check whether voltages have fallen below 50 V before touching live parts!
