Peripheral Devices - Mitsubishi Electric FR-E540 K-EC Series Instruction Manual

2.3.6 Peripheral devices

(1) Selection of peripheral devices
Check the capacity of the motor to be used with the inverter you purchased.
Appropriate peripheral devices must be selected according to the capacity.
Refer to the following list and prepare appropriate peripheral devices:
Motor
Inverter Type
Output
(kW)
FR-E540-0.4K-EC 0.4
FR-E540-0.75K-EC 0.75
FR-E540-1.5K-EC 1.5
FR-E540-2.2K-EC 2.2
FR-E540-3.7K-EC 3.7
FR-E540-5.5K-EC 5.5
FR-E540-7.5K-EC 7.5
FR-E520S-0.4K-EC 0.4
FR-E520S-0.75K-EC 0.75
FR-E520S-1.5K-EC 1.5
FR-E520S-2.2K-EC 2.2
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.
3. The inverter input side magnetic
contactor to
between the applicable ranges A, B
and C shown on the right, depending
on the power supply capacity and
wiring length. For the FR-E520S-0.4K to 0.75K-EC 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.
