Main power terminals
Do not connect 3-phase model to one-phase power. R/L1, S/L2 and T/L3
has no phase-sequence requirement, it can be used upon random
selection.
It is recommend to add a magnetic contactor (MC) to the power input
wiring to cut off power quickly and reduce malfunction when activating
the protection function of the AC motor drive. Both ends of the MC
should have an R-C surge absorber.
Fasten the screws in the main circuit terminal to prevent sparks condition
made by the loose screws due to vibration.
Please use voltage and current within the specification.
When using a general GFCI (Ground Fault Circuit Interrupter), select a
current sensor with sensitivity of 200mA or above and not less than
0.1-second operation time to avoid nuisance tripping.
Please use the shield wire or tube for the power wiring and ground the
two ends of the shield wire or tube.
Do NOT run/stop AC motor drives by turning the power ON/OFF.
Run/stop AC motor drives by RUN/STOP command via control terminals
or keypad. If you still need to run/stop AC motor drives by turning power
ON/OFF, it is recommended to do so only ONCE per hour.
Output terminals for main circuit
When it needs to install the filter at the output side of terminals U/T1,
V/T2, W/T3 on the AC motor drive. Please use inductance filter. Do not
use phase-compensation capacitors or L-C (Inductance-Capacitance) or
R-C (Resistance-Capacitance), unless approved by Delta.
DO NOT connect phase-compensation capacitors or surge absorbers at
the output terminals of AC motor drives.
Use well-insulated motor, suitable for inverter operation.
Terminals for connecting DC reactor, external brake resistor, external
brake resistor and DC circuit
This is the terminals used to connect the DC reactor to improve the
power factor. For the factory setting, it connects the short-circuit object.
Please remove this short-circuit object before connecting to the DC
reactor.
+1/DC+
When the AC Motor Drive is connected directly to a large-capacity power
transformer (600kVA or above) or when a phase lead capacitor is
switched, excess peak currents may occur in the power input circuit due
to the load changes and the converter section may be damaged. To
