Type
Connects line power to the drive.
Drives with single phase 200 V input power use terminals R/L1
and S/L2 only (T/L3 must not be used).
Connects to the motor.
Available for connecting a braking resistor or the braking resistor
unit option.
These terminals are shorted at shipment. Remove the shorting bar
to install a DC choke.
For connecting a DC power supply.
Note: DC power supply input terminals (+1, –) are both UL and
EU certified.
Grounding Terminal
For 200 V class: 100 Ω or less
For 400 V class: 10 Ω or less
