Note
1)
In standard configuration on 30kW and smaller units, the control power inputs are connected to the
main circuit power source. These can be easily separated if necessary.
Note
2)
800Hz is possible with special modifications, but a de-rating of the output current raing is necessary.
Note
3) Optional.
Note
4)
Programmable ON/OFF output terminal signals. Can be allocated from 62 types of signals.
Note
5)
Programmable analog output terminal. Can be allocated from 14 types of signals.
Note
6}
The
11
contact input terminals (of which three are optional) are programmable contact input
terminals, and can be
allocated from 52 types of signals.
Note
7) Three holes can be opened for input main circuit wiring, output main circuit wiring, and control
circuit wiring, but the openings must be securely covered after wiring.
Note
8}
When the cover
is
removed, always install the unit
in
a panel
so
that charged sections
are
not
exposed.
22kW and larger units can handle
-10 to
50°C
without removal of the cover.
Note
9)
22kW and larger units have a large opening instead of a wiring cover, an there is
no
space for
bending externally-connected cables inside the unit. Use the optional wire opening cover when
the unit is not installed in a
panel.
