Figure 4: An example of typical installation of SMC 133 instrument — options L or S for various LVDC power
supplies and option U for universal LVAC. Typical connection options for voltage measurements: star, delta and
single phase feeders. Option E (left) for Ethernet port remote communication, option U (right) for local USB
communication port (all instruments provide RS485 serial line).
