* Special feature:
The assignment and colour sequence of the connector pin assignment of the temperature display
VDD 500 is different from that of the system centres Virtus 5 / CI 5xx0 / CI 4xx0 / and the pack
controller VPC 5000.
* A
120 Ohm
terminating resistor is permanently integrated in the case controller between terminals
2
and
3
. This means that the DISPLAY interface represents the beginning of the line, termination at
these terminals must
not
be done!
It is only at the end of the line (at the last temperature display VDD 500)
that a terminating
resistor of
120 Ohm
must
be installed.
Mounting instructions
Insert one end of the 120 Ohm terminating resistor
and
one wire (A-
brown / B+ white) with the enclosed TWIN wire end sleeve.
