Description
Cables
Device to transfer the electronic signals
Output reactor
Extend the effective transimiting distance of the
inverter to control the sudden high voltage when
switchiong on/off the IGBT of the inverter.
C.2 Power supply
Check that the voltage rating of the inverter complies with the supply voltage.
C.3 Cables
C.3.1 Power cables
Size the input power and motor cables according to local regulations.
Note:
A separate PE conductor is required if the conductivity of the cable shield is not sufficient for the purpose.
C.3.2 Control cables
All analog control cables and the cable used for the frequency input must be shielded.
The relay cable needs the cable type with braided metallic screen.
Note: Run analog and digital signals in separate cables.
Check the insulation of the input power cable according to local regulations before connecting to the drive.

Note:
1. It is appropriate to use the recommended cable size under 40
℃
and rated current. The wiring distance should
be no more than 100m.
2. Terminals P1, (+), PB and (-) connects the DC reactor options and parts.
C.4 Breaker and electromagnetic contactor
It is necessary to add fuse for the avoidance of overload.
It is appropriate to use a breaker (MCCB) which complies with the inverter power in the 3-phase AC power and
input power and terminals. The capacity of the inverter should be 1.5-2 times of the rated current.
Due to the inherent operating principle and construction of circuit breakers, independent of the
manufacturer, hot ionized gases may escape from the breaker enclosure in case of a
