*Contact LSIS Customer Support before configuring the P2 (+) and N (-) terminals as the DC common
source. There are a few factors that require special attention for this application.
Note
External DC reactors cannot be used with 30 – 75 kW inverters. To use a DC reactor with these
inverters, purchase a 30 – 75 kW inverter that has a built-in DC reactor.
•
When a built-in DCR unit is present, the P1 (+) and P (-) terminals are connected to the r eactor’s
input and output terminals respectively.
•
If your product does not have a built-in DCR unit, the P2 (+) and N (-) terminals may be used as
the common DC source. Do not use the P1 (+) terminal as the common DC source, as this may
result in product damage.
•
Use the P2 (+) and N (-) terminals to connect a dynamic braking resistor to the inverter. Do not
connect the dynamic braking unit to the P1 (+) terminal, as this may result in product damage.
•
Contact LSIS Customer Support before configuring the N (-) terminal as the DC common source.
There are a few factors that require special attention for this application.

Connect the cables from the dynamic braking unit to the P2 (+) and N (-) terminals to utilize an
external dynamic braking unit.
