Peripheral Devices - Mitsubishi Electric 800 Series Instruction Manual

2.1.2

Peripheral devices

Check the model of the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity.
Refer to the following table for right selection.
 Molded case circuit breaker / earth leakage circuit breaker
• The following shows the rated current of the molded case circuit breaker (MCCB) or earth leakage circuit breaker (ELB).
Inverter model
FR-E860-0.75K(0017)
FR-E860-1.5K(0027)
FR-E860-2.2K(0040)
FR-E860-3.7K(0061)
FR-E860-5.5K(0090)
FR-E860-7.5K(0120)
NOTE
• Select an MCCB according to the power supply capacity.
• Install one MCCB per inverter.
• For the use in the United States or Canada, refer to "Instructions for UL and cUL" in the document enclosed with the product,
and select an appropriate fuses.
• When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to the
inverter model, and select cables and reactors according to the motor output.
• When the breaker installed on the inverter input side is shut off, check for the wiring fault (short circuit), damage to internal
parts of the inverter etc. The cause of the output shutoff must be identified and removed before turning ON the power of the
breaker.
 Magnetic contactor at the inverter's input line
• This is a matrix showing the model name of the Mitsubishi magnetic contactor to be installed at the inverter's input line
according to the selected inverter and rating.
