3.3.5 Details of connection
Connect (1) Main power supply circuit, (2) DC link circuit, (3) Grounding circuit, (4) Control circuit, (5) Auxiliary
control power input circuit in this order.
For the cable size, refer to Section 3.3.7 "Cable Size Applicable to Main Circuit."
• Check that the power is turned off (with open circuit) before conducting wiring.
Electric shock may result.
• Do not turn on the converter with missing or dropping parts or damage given during transportation.
Electric shock or fire may result.
• Check that the phases and rated voltage of the product agree with the phases and voltage of the AC power
supply.
Injury may result.
• Keep consistency in the polarity between the DC power supply terminals P (+) and N (-) of the converter and
the main circuit DC terminals P (+) and N (-) of the inverter.
Fire may result.
• The PN wiring length to the DC link bus terminal must not exceed 5 m.
Fire may result.
(1) Main circuit power supply input terminals (L1/R, L2/S and L3/T)
RHC132S to 450S-69D (Filter stack)
Connect the L1/R, L2/S and L3/T main circuit power supply terminals to the U0, V0 and W0 terminals of the
dedicated filter stack.
