5 Installation Requirements for Options
5.1 AC Input Reactor
The AC input reactor is an option used to suppress the harmonics in the input current.
In applications where strong suppression of harmonics is required, install an external
AC input reactor.
If an AC input reactor is required, ensure that sufficient installation space is reserved
in the cabinet.
5.2 Output Reactor
With an output reactor installed on the output side of the AC drive, the excessive dV/
dt can be reduced, lowering the voltage stress on the motor winding. This protects
the motor winding, lowers the motor temperature, and prolongs the service life of the
motor.
5.3 Fuse, Contactor, and Circuit Breaker
When the fuse is damaged or the circuit breaker trips, do not immediately energize the
product or operate the peripheral equipment. Wait at least for the time specified on the
warning label to prevent personal injury and equipment damage.
To meet the requirements of IEC/EN 61800‑5‑1 and UL61800‑5‑1, a fuse/circuit
breaker must be connected on the input side to prevent accidents caused by internal
short circuits.
5.4 EMC Filter
The optional EMC filter is able to meet the EN61800‑3 category C2 emission limits.
EMC filters are recommended to be installed according to the following requirements:
● The filter must be reliably grounded.
● The EMC filter must be installed close to the input terminals of the equipment, and
the cables connecting them must be shorter than 30 cm.
● The grounding terminal of EMC filter and the grounding terminal of equipment
must be connected together, and the filter and the equipment must be installed
on the same conductive installation surface, which is connected to the main
ground of the cabinet.
