Connecting the System to the Line Voltage
The system has two hot-swappable, redundant power supply units.
V
CAUTION!
The power supply units automatically adjust to a mains voltage between
100 V - 127V or 200 V - 240 V. The system may be put into operation only
if the mains voltage range corresponds to the system’s voltage range.

Ê
Connect first the insulated connector of the power cables to the power
supply units of the system (1), and the power plug (2) into the mains socket
strip of the rack (see technical manual of the rack).
V
CAUTION!
Connect first always the power cable to the power supply units, and after
it to the mains.
I
Phase redundancy in the power supply of the system can be set up if
each of the power supply units are directly connected either to two
different phases or to two different mains power circuits.
V
CAUTION!
Make sure that both power supply units are populated!
