8 Installing the power supply unit
8.1 Safety regulations and installation notes 8.2 Mains connection
The device can be connected to single-phase AC or three-
phase power grids (TN-S, TN-C, TT, and IT) while consider-
ing the nominal input voltage.

WARNING: risk of electric shock!
Only qualified specialist personnel may in-
stall, start up, and operate the device. Ob-
serve the national safety and accident
prevention regulations.
Prior to installation, disconnect the input volt-
age and make sure that it cannot be switched
on again unintentionally.
Mains connection must be performed by spe-
cialist personnel and protection against elec-
tric shock ensured.
Stellen Sie sicher, dass das Gerät nach den
Bestimmungen der IEC 60950 außerhalb der
Stromversorgung schaltbar ist (z. B. durch
den primärseitigen Leitungsschutz).
Cover termination area after installation in or-
der to avoid accidental contact with live parts
(e.g., by installing in a control cabinet).
Protect the device against ingress by foreign
bodies, e.g., paper clips or metal parts.
WARNING: risk of electric shock!
Make sure that all supply lines are sufficiently
dimensioned and have sufficient fuse protec-
tion.
Make sure that all output cables are dimen-
sioned accordingly for the maximum device
output current or have separate fuse protec-
tion.
WARNING: risk of electric shock!
Never open or repair the device yourself.
Internal fuses will only blow in the event of de-
vice malfunction. Do not modify or attempt to
repair the device. Send the device to the fac-
tory for examination.
For operation on two of the phase conductors
of a three-phase system, an isolating facility
for all poles must be provided.
