Connecting the supply voltage

Apart from the primary PROFINET, EtherNet/IP, Profibus DP and Modbus
TCP interfaces, all the weighing terminal's connections are located on the
underside.
S The supply voltage is connected to terminal KL2.1 or KL2.3.
S The supply voltage can be connected to terminal KL2.2 or KL2.4 and trans­
mitted to the next weighing module. A maximum of eight weighing modules
can be connected in this way.
S The supply voltage is 12 V (–15%) to 30 V (+10%) at a max. current
consumption of 1.3 A. Only safety extra low voltages may be connected.
S The supply voltage connection is protected against polarity reversal.
