Dc Bus Terminal (P, N) Or Brake Terminal (B, P) - JPS PDA Series Instruction Manual

2.6 DC bus terminal (P, N) or Brake terminal (B, P)

!
CAUTION
Some models with power terminal marked P and N, these models does not include Brake transistor inside the inverter.
Customer may use extra Brake Transistor Module for discharge brake function.
For models that include braking transistor, the power terminal will mark P and B. User can connect suitable resistor to
the P & B terminals directly.
Here is the recommended table for discharge resistors:

! Warning：Never connect resistor to P & N terminal
If the terminals are P & N, must add external braking unit.
2.7 A.C.L.
When power supply capacity is larger than 500KVA and/or using thyrister, phase advance capacitor etc. from same
power supply, must fitting A.C.L. at R.S.T. power input side to curb instantaneous current and to improve power ratio.
Here is the recommended table for A.C.L.:

Note: The A.C.L. for 220V and 380V/440V have different induction values, please does not mix up.
