CAUTION
1. Check that the number of phases and the
rated volta
g
e of this product correspond
to the number of phases and volta
g
e of the
AC power suppl
y
.
Otherwise fire could occur.
2. Do not connect the AC power suppl
y
to the
output terminals (U, V, W).
Otherwise in

to
the DC terminals P(+), N(-).
Otherwise fire could occur.
