3-Phase Wye
Single phase, 2 wire
For the separate protective ground, you need a green/yellow ground wire with a
cross section of at least 4
mm
2
in addition to the main protective earthing terminal.
The ground wire must be connected permanently to the ground terminal on the
side of each R&S
QPS panel and earth.
The ground terminal is located on the power supply. Connect the terminal to the
protective grounding system of the building or room where the scanner is installed.

2. Make sure that the power supply is adequately protected against overcurrent. Oth-
erwise the fuse can blow.
We recommend that you use a power cable that is rated for a 16
A (included in the
delivery) and connect each panel to a separately protected power circuit (at least
10
A).
If you cannot connect the panels to separate power circuits, make sure that the
system is protected:
● By a fuse with at least 20
A in 200
V networks.
● By a fuse with at least 16
A in 230
V networks.
3. If the voltage drops to 70
% for 500
ms, a reboot occurs.
Supplying the system with power
Always complete all connections (LAN, USB etc.) before connecting the panels to the
power supply.
Refer to the data sheet for power rating and electrical safety compliance.
1. Make sure that the protective ground connection is established.
2. Connect the power cord to the panel's AC inlet.
3. Connect the power cord to the AC power source.
4. Turn on the mains power switch (position "I") on both panels.
