● The specications are valid only if the conductors of the PE cable and AC power cable use the
same material. If the materials are dierent, ensure that the conductor cross-sectional area of
the PE cable produces a conductance equivalent to that of the cable specied in the table.
● The specications of the PE cable are subject to this table or calculated according to IEC
60364-5-54.
5.2.2 RS485 Communication
If RS485 is selected, connect an RS485 communications cable to the SUN2000, but
the AC power cable does not need to connect to a SmartLogger that supports
MBUS.
