LEGEND:
1)
Tri-state-input:
pin 2 on -V
O
=
discharge test mode
pin 2 on +V
O
=
boost charge mode
Note:
For 60/108V units: For the connection to +Vo an additional series resistor has to be used
(60 V: 18kOhm; 110 V: 56kOhm).
2)
Connection of temperature sensor with 2-pole wire to pin 7 (+) and pin 10 (-)
Note:
If several modules are paralleled, all of pin 7 and pin 10 respectively of each unit have to be inter-
connected.
3)
At active current sharing mode of paralleled units all pin 8 of each module have to be intercon-
nected. The analog GND (pin 10) has to be interconnected too.
ATTENTION:
If active current sharing mode is enabled, the use of external decoupling diodes and
fuses as well in minus on the output side is
not
allowed.
4)
External switch ON/OFF with optocouppler: internal resistor 2.7kOhm, I
min
5 mA, I
max
= 10 mA
Note:
The input is free of potential with safe electrical decoupling to primary side (500V DC to secondary
side).
5)
The relay outputs are free of potential with safe electrical
decoupling to primary side (500V DC to secondary side).
