Connect to the commercial power supply.
Keep these terminals open when using the high power factor
converter (FR-HC, MT-HC) or power regeneration common converter
(FR-CV).
Connected to the AC power supply terminals R/L1 and S/L2. To
retain the fault display and fault output or when using the high power
factor converter (FR-HC, MT-HC) or power regeneration common
converter (FR-CV), remove the jumpers from terminals R/L1 and R1/
L11, and S/L2 and S1/L21 and apply external power to these
terminals.
The power capacity necessary when separate power is supplied from
R1/L11 and S1/L21 differs according to the inverter capacity.
200V FR-F720-00630 or lower
class
400V FR-F740-00310 or lower
class
Connect the brake unit (FR-BU2, FR-BU, BU and MT-BU5), power
regeneration common converter (FR-CV), high power factor converter
(FR-HC and MT-HC) or power regeneration converter (MT-RC).
For the FR-F720-02330 (FR-F740-01160) or lower, remove the
jumper across terminals P/+ and P1 and connect the DC reactor. (Be
sure to connect the DC reactor supplied with the FR-F720-03160
(FR-F740-01800) or higher.)
When a DC reactor is not connected, the jumper across terminals
P/+ and P1 should not be removed.
For earthing (grounding) the inverter chassis. Must be earthed
(grounded).
