Terminal function description
Connect these terminals to a three-phase squirrel cage motor.
Connected to terminals P/+ and N/-. To retain the fault display and fault
output, remove the jumpers across terminals R1/L11 and S1/L21, and apply
external power through these terminals.
The power capacity necessary when separate power is supplied from R1/L11
and S1/L21 is 80 VA.
Wire the terminals between the converter unit and between the inverter as
shown in the terminal connection diagram. (Wire one terminal P to another
terminal P, and do likewise for terminal N.)
For earthing (grounding) the inverter chassis. This must be earthed
(grounded).
Terminal function description
Connect these terminals to the commercial power supply.
Connected to the AC power supply terminals R/L1 and S/L2. To retain the
fault display and fault output, remove the jumpers across terminals R/L1 and
R1/L11 and across S/L2 and S1/L21, and supply external power to these
terminals.
The power capacity necessary when separate power is supplied from R1/L11
and S1/L21 is 80 VA.
Wire the terminals between the converter unit and between the inverter as
shown in the terminal connection diagram. (Wire one terminal P to another
terminal P, and do likewise for terminal N.)
For earthing (grounding) the converter unit chassis. This must be earthed
(grounded).
