Ensure that the motor is configured for the correct supply voltage: single /
three-phase 230 V MICROMASTERS must not be connected to a 400 V
three-phase supply.
♦
When synchronous motors are connected or when coupling several motors in
parallel, the inverter must be operated with voltage/frequency control
characteristic (P1300 = 0, 2 or 3).
CAUTION
After connecting the power and motor cables to the proper terminals, make sure
that the covers have been replaced properly before supplying power to the unit!
NOTICE
♦
Ensure that the appropriate circuit-breakers/fuses with the specified current
rating are connected between the power supply and inverter (see chapter 5,
Tables starting on page 160).
