2.1 Peripheral devices
Check the inverter model of the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity.
Refer to the following list and prepare appropriate peripheral devices.
∗1 ySelect a MCCB according to the power supply capacity.
yInstall one MCCB per inverter.
∗2 For the use in the United States or Canada, select an UL and cUL certified fuse with Class T fuse equivalent cut-off
speed or faster with the appropriate rating for branch circuit protection. Alternatively, select a UL489 molded case circuit breaker (MCCB). (Refer to page 46)
∗3 Magnetic contactor is selected based on the AC-1 class. The electrical durability of magnetic contactor is 500,000 times. When the magnetic contactor is
used for emergency stop during motor driving, the electrical durability is 25 times.
If using an MC for emergency stop during motor driving, select an MC regarding the inverter input side current as JEM1038-AC-3 class rated current. When
using an MC on the inverter output side for commercial-power supply operation switching using a general purpose motor, select an MC regarding the motor
rated current as JEM1038-AC-3 class rated current.
∗5 The power factor may be slightly lower.
∗6 Single-phase 100V power input model is not compatible with DC reactor.

∗4 When connecting a single-phase 100V power input model to a power transformer (50kVA or more), install an AC reactor (FR-HAL) so that the performance
is more reliable. ( Refer to Chapter 3 of the Instruction Manual (Applied))
NOTE
y When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to the inverter model,
and cable and reactor according to the motor output.
y When the breaker on the inverter input side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter, etc.
Identify the cause of the trip, then remove the cause and power ON the breaker.
