Mitsubishi Electric FR-E500 Instruction Manual page 56

Note: 1. Select the type of the no-fuse breaker
(NFB) in response to the power
supply capacity.
2. The power supply cable size of the
motor indicated assumes that its
length is 20m (65.62 feet).
3. The inverter input side magnetic
contactor
between the applicable ranges A, B
and C shown on the right, depending
on the power supply capacity and
wiring length. For the FR-E520-0.4K to 1.5K-NA, FR-E510W-0.4K to 0.75K-
NA, choose the S-N10 when the power factor improving reactor (FR-BEL or
FR-BAL) is used.
4. When the inverter capacity is greater than the motor capacity, choose the
breaker and magnetic contactor in accordance with the inverter type and
choose the cables and power factor improving reactor in accordance with
the motor output.
z Installation and selection of no-fuse breaker
Install a no-fuse breaker (NFB) in the power supply side for protection of the inverter's
primary wiring. Refer to the previous table and choose the NFB according to the
inverter's power supply side power factor (which changes with the power supply
voltage, output frequency and load). Especially for a completely electromagnetic type
NFB, the one with a larger capacity must be selected since its operational
characteristics change with harmonic currents. (Check the data of the corresponding
breaker for confirmation.) Also, the earth leakage circuit breaker used should be
durable against harmonic/surge (such as the Progressive Super Series).
