Connection of stand-alone option unit
(2) Connection example with the FR-BR(-H) type resistor
2.4.3
Connection of the high power factor converter (FR-HC)
When connecting the high power factor converter (FR-HC) to suppress power harmonics, perform wiring securely as shown
below. Incorrect connection will damage the high power factor converter and inverter.
below. Incorrect connection will damage the high power factor converter and inverter.
∗1
Connect the inverter terminals (P/+ and N/-) and brake unit (FR-BU2) terminals so that their terminal names match
with each other.
(Incorrect connection will damage the inverter and brake unit.)
with each other.
(Incorrect connection will damage the inverter and brake unit.)
∗2
When the power supply is 400V class, install a step-down transformer.
∗3
The wiring distance between the inverter, brake unit (FR-BU2) and resistor unit (FR-BR) should be within
5m(16.4feet) each. Even when the wiring is twisted, the cable length must not exceed 10m(32.8feet).
5m(16.4feet) each. Even when the wiring is twisted, the cable length must not exceed 10m(32.8feet).
∗4
Normal: across TH1-TH2...close, Alarm: across TH1-TH2...open
∗5
A jumper is connected across BUE and SD in the initial status.
NOTE
Do not remove a jumper across terminal P/+ and P1 except when connecting a DC reactor.
∗1
Always keep the power input terminals R/L1, S/L2, T/L3 open. Incorrect connection will damage the inverter.
∗2
Do not insert an MCCB between the terminals P/+ and N/- (between P and P/+, between N and N/-). Opposite polarity of terminals N/- and P/+ will
damage the inverter.
damage the inverter.
∗3
Use Pr. 178 to Pr. 182 (input terminal function selection) to assign the terminals used for the X10, RES signal. (Refer to page 113)
∗4
Be sure to connect terminal RDY of the FR-HC to the X10 signal or MRS signal assigned terminal of the inverter, and connect terminal SE of the
FR-HC to terminal SD of the inverter. Without proper connecting, FR-HC will be damaged.
FR-HC to terminal SD of the inverter. Without proper connecting, FR-HC will be damaged.
NOTE
The voltage phases of terminals R/L1, S/L2, T/L3 and terminals R4, S4, T4 must be matched.
Use sink logic (factory setting) when the FR-HC is connected. The FR-HC cannot be connected when source logic is
selected.
Do not remove a jumper across terminal P/+ and P1.
