When using a braking resistor built-in type
A built-in braking resistor is connected to terminals P(+) and DB at the factory as shown below.
If you want to connect a DC reactor together with the
built-in braking resistor, follow the instructions given on
the previous page.
Figure 2.9 Built-in Braking Resistor Con-
nection
(This example shows the braking resistor
built-in type FRN1.5C1S-221)
Note: A box () in the above model name replaces
A, C, E, or J depending on the shipping destination.
- If both wires of the built-in braking resistor
have been disconnected, you may con-
nect them to terminals P(+) and DB in
either combination.
- The braking resistor built-in type is avail-
able only in three-phase 200 V and
three-phase 400 V models of 1.5 kW o
more.
Never insert a braking resistor between terminals P(+) and N(-), P1 and N(-), P(+) and P1, DB
and N(-), or P1 and DB.
Doing so could cause fire.
g DC link bus terminals, P (+) and N (-)
These are provided for the DC link bus powered system. Connect these terminals with terminals P(+)
and N (-) of other inverters.
Consult your Fuji Electric representative if these terminals are to be used.
