Battery connection

The maximum connection voltage (battery voltage) 450 V= (780 V=),
do not exceed even for a short time - risk of destruction!
Error message: OVERVOLTAGEF1
= slow-blow fuse
Programming an output for the pre-charge:
The output Dout1 switches the relay K3 if the DC link voltage (DC BUS) is greater than variable 1.
Attention:
The power connection has no reverse polarity protection.
If the polarity of the power connection is reversed, the unit may be destroyed.
Type Battery connection
250/400
Battery connection <2 m, from 2 to 10 m make connection stronger.
Use additional capacity from 10 m! Lay positive and negative cables in parallel.
Maximum connection cross-section 50 mm2, cable lug for M10.
