Note 1. The Braking Unit or Braking Resistor Unit cannot be connected to the Inverter
(18.5 kW to 160 kW). However, 185-kW to 300-kW models can be connected.
Note 2. Make sure that terminals R and R1, S and S1, and T and T1 are short-circuited.
These terminals are short-circuited
with short bars before shipping. Be sure to re
-
move the short bars, however, when using 12-pulse rectification.
Note 3. Terminals
L1
1 (R1), L21 (S1), and L31 (T1) are not available on the 185- to 300-kW
Inverters.
Note 4. The
185- to 300-kW Inverters do not have built-in DC
reactors, nor can DC reactors
be externally connected.
