NOTICE!
1 Danger of destroying the inverter's RS485 input. Pin 1 of
the RJ12 socket of the Web‘log data logger carries 24 V DC.
Never connect the alternative data connection cable to
pin 1!
3.6.5 RS485 termination
To prevent data transmission errors, the start and end of the RS485 bus
should be terminated:
n
The external data logger (at the start of the data connection) must be
terminated according to the manufacturer's specifications.
n
The last inverter (at the end of the data connection) is terminated by
plugging the optionally available termination plug into the free RJ45
socket (for RS485 bus) (see table in
Ä
Chapter 2.2 „Identification“ on page 7
under 'Optional accessories').
3.6.6 RS485 addressing
Every inverter must be assigned its own unique address for communica‐
tion between the bus master and the slaves.
Every inverter is set with an address of 1 at the factory. This means that
the addresses must be adjusted in systems having more than 1 inverter.
