Power Supply
The device is optionally equipped with two power inputs and power supply units. If one power supply fails, due to
malfunction of the feeding power line or the power supply unit itself, the device will automatically switch over to the
other power supply unit. In order to make the power supply redundant, both power inputs must be connected to the
mains supply, if possible to different phases, power supply systems, or even better, one of them to an uninterrupted
power supply (UPS).
The power supply units operate with mains voltage of 100 ... 240 V and frequency of 50 … 60 Hz. Thus the device
can be used throughout the world without any modifications or transformers.
Be aware that the switched-mode power supplies operate with high voltages! Coming into contact with them
can lead to considerable electric shock that may result in death! To prevent electric shocks do not remove
any covers!
