*1 Remove the jumper across terminals R/L1 - R1/L11, S/L2 - S1/L21 of the inverter, and connect the control circuit power
supply to the R1/L11 and S1/L21 terminals. The power input terminals R/L1, S/L2, T/L3 must be open. Incorrect connection
will damage the inverter. (E.OPT (option alarm) will occur. (
Refer to page 402.
)
*2 Do not insert the MCCB between terminals P/+
−
N/- (P
−
P/+, N
−
N/-). Opposite polarity of terminals N, P will damage the
inverter.
*3 Use Pr. 178 to Pr. 189 (input terminal function selection) to assign the terminals used for the X10 (X11) signal. ( Refer to page
222.) For communication where the start command is sent only once, e.g. RS-485 communication operation, use the X11
signal when making setting to hold the mode at occurrence of an instantaneous power failure. (
Refer to page 199.)
*4 Connect the power supply to terminals R1 and S1 of the MT-HC via an insulated transformer.
CAUTION
⋅
The voltage phases of terminals R/L1, S/L2, T/L3 and terminals R4, S4, T4 must be matched.
⋅
Use sink logic when the MT-HC is connected. The MT-HC cannot be connected when source logic (factory setting) is selected.
⋅
When connecting the inverter to the MT-HC, do not connect the DC reactor provided to the inverter.
