For inverters, the address range can be selected between 1
and 32. You can defi ne the address for each inverter using the
confi guration menu (see Operating Instructions).
IMPORTANT
Ensure that the A and B wires are properly connected.
Communication is not possible if the wires are reversed.
(D) SYM-bus connection:
To connect several blueplanet inverters, terminal SYM+ of
one blueplanet is connected to terminal SYM+ of the other
blueplanet. Terminal SYM- is connected in the same manner.
A twisted shielded data cable is required for this. A connection
diagram is displayed in fi gure 5.22. The total length of the CAN
bus wiring should not exceed 650 feet with standard wire. With
a high quality CAT5 CAN-cable a total length of 4000 feet is
possible. Proper polarity must be maintained or devices will not
be able to communicate.
In fi gure 5.22, a terminating resistor is activated (set to “ON”)
in the fi rst and to the last inverter in the chain. For proper signal
transmission, the fi rst and the last unit in a chain must have
a terminating resistor. The terminating resistors in the other
inverters of the chain must be deactivated (set to “OFF”). In
the fi rst and the last unit of the chain, switch “CAN” is set to
“ON”. The switch is on circuit board mounted inside the door
of the inverter.
With a bus system such as the CAN, each unit sharing this
bus must possess a unique address. The address range can
be selected between 1 and 32. You can defi ne the address for
each inverter using the parameter menu.

interface using the KACO pro LOG
(A) Connecting the fault signal relay
The inverter is equipped with a potential-free relay contact to
signal faults. This contact closes if a fault occurs. The contact
is designed as a NO contact and marked as “ERR” on the
connection terminal. Maximum contact load
•
DC: 30 V / 3 A.
• AC: 250 V / 1.5 A.
IMPORTANT
In the event of failure of the grid-feed phase (power failure on
the public grid), the relay will not trigger. If this happens, all LEDs
and the display go out. The inverter is shut down completely.
A fault signal cannot be sent.
(B) Connecting the S0 output
The inverter is equipped with an S0 pulse output. Items such
as a large display can be connected to it. The pulse rate is
adjustable (see section 5.9, “Parameter programming”).
(C) The RS485 interface connection
The connection terminal (Figure 5.20) is on the blueplanet
communication circuit board. To connect several blueplanet
inverters, terminal A of one blueplanet is connected to terminal
A of the other blueplanet. Terminal B is connected in the same
manner. A twisted, shielded data cable is required for this. The
connection to the KACO proLOG is established similarly to the
interconnection of inverters. A connection diagram is displayed
in fi gure 5.21. The total length of the RS485 wiring should
not exceed 4,000 feet. Proper polarity must be maintained or
devices will not be able to communicate.

The terminating resistors in the inverters of the chain must be
deactivated (set to “OFF”). In the last unit of the chain, switch
“RS485” to “ON”. The switch is on the circuit board mounted
inside the door of the inverter.
With a bus system such as the RS485, each unit sharing this
bus must possess a unique address, regardless of whether it is
an inverter or any other device. The exception is the monitoring
device which is the master. This unit does not need an address.
