Connecting the
battery commu-
nication cables
1
Strip 10 mm from the single conductors
and mount the ferrules if necessary.
IMPORTANT!
Connect the individual conductors to an
appropriate ferrule if several individual
conductors are connected to one input of
the push-in terminals.
2
Insert the cable into the respective slot
and check the cable is securely retained.
IMPORTANT!
Use only twisted pairs for connecting
"Data +/-" and "Enable +/-", see section
Permitted cables for the data commu-
nication area on page 57.
Twist the cable shield and insert into the
"SHIELD" slot.
IMPORTANT!
Improperly fitted shielding can cause data
communication problems.
For the wiring proposal recommended by Fronius, see page 158.
Terminating res-
istors
It may be possible for the system to function without terminating resistors. However, ow-
ing to interference, the use of terminating resistors according to the following overview is
recommended for trouble-free functioning.
For permissible cable and max. distances see chapter Permitted cables for the data
communication area on page 57.
IMPORTANT!
Terminating resistors that are not positioned as illustrated can result in interference in the
data communication. If the terminating resistor on the battery cannot be deactivated, the
battery is to be set up at the bus end (see option 2, 3).
