If the PRIMES USB connecting cable and PRIMES power supply are connected simultaneously
during initial installation, the USB driver may not be recognized in exceptional cases. During initial
installation, only connect the device via the USB connecting cable. Once the USB connection has
been established, the power supply can be connected as necessary.
1. Connect the device to the PC via the PRIMES USB connection cable (plug/plug):
•
For a PC with an Internet connection, the USB driver is automatically installed.
•
For a PC without an Internet connection, the USB driver must be installed manually (see chapter 9.4.3 on
page 27). The USB driver has to be installed before the device is connected.
2. If necessary, connect the power supply unit via the adapter to the 9 pin D-Sub socket (RS485) of the
device.

In general, a USB interface without additional interference suppression measures is not in conformi-
ty with the EMC directive. In industrial environments with strong sources of interference, there could
therefore be disruptions in the connection and disruptions in data transmission.
