By using USB or Ethernet as communication interface the power supply unit included could be
directly connected to the RJ-12 jack of the device.
For usage of the RS232 interface a special RS232 connection cable is available (see 2.2. Available
accessories and spare parts). In that case the included power supply unit has to be connected to
the RJ-12 jack of the connection cable. The RJ-12 plug of the connection cable has to be connect-
ed to the RJ-12 jack of the device.
CAUTION:
The device has to be supplied by a limited power supply (e.g. NEC Class 2/LPS power sup-
ply) according IEC EN 60950, only!
Reversing the polarity of the supply voltage may destroy the device.
