Possible reason
•
Check the capacitance in the
capacitor bank, refer to section
"P03 - Capacitor bank and
charging test".
•
If the capacitance is too low, one or
more capacitor rows are
disconnected. If there is an internal
error in a capacitor, the whole row
is disconnected by a fuse, refer to
page 130** and section "Capacitor
bank".
•
If the error appears after working
on the capacitor bank, it may be
that the internal residual voltage in
the modules was too high when
they were connected to each other.
This caused the fuse to blow, refer
to page 130**.
•
Check that S10 on D7 is switched
off.
•
If the error appears after working
on the capacitor bank, check the
cabling and the connections to the
capacitor bank, refer to page
130**.
•
Check fuse U8 on D8 and fuse U1
on D7.
•
Check the capacitance in the
capacitor bank, refer to section
"P03 - Capacitor bank and
charging test".
•
Internal short-circuiting in a
capacitor or in the capacitor bank,
refer to section "Capacitor bank".
