Illustration 8.5 Signal Connection X3
Here is an example of how to wire signal plug X3 in order
to enable the hardware:
•
Pin 13 to 11 to 9 to 7
•
Pin 14 to 12 to 10 to 8
WARNING
HIGH VOLTAGE!
By using the above detailed wiring example the DC 300 V
output voltage is immediately available once the AC 400 V
supply voltage is connected.
Use a relay between pins 9 and 7 to control the output
voltage. The DC 300 V output voltage is enabled when the
relay is closed.

VLT ISD Power Supply Module Operating Instructions
Optocoupler active if output
voltage U o reduced (90 V) is OK
(Not valid for ISD 410)
Optocoupler active if output
voltage U o nominal (300 V) is OK
Optocoupler active in case of
any failure / error
Output will be switched on if
10-28 V applied here
Setpoint U o nominal (300 V) if
10-28 V applied here, otherwise
U o reduced (90 V)
Setpoint I o limited nominal (10.2 A)
if 10-28 V applied here, otherwise
I o limited reduced (7.8 A)
This potential-free 12 V auxiliary
voltage can be used to supply the
above mentioned optocoupler
inputs
