For indoor use only; avoid direct sunlight. Place on a sturdy, stable surface to prevent severe vibrations. Ensure the environment is free of dust, corrosive gases, and flammable or explosive materials. Keep away from strong magnetic and electric fields. Ensure adequate ventilation; leave at least 10 cm of space around the device for heat dissipation, and do not block the cooling fan vents. Operating Environment: Temperature 5°C to 35°C, relative humidity ≤65%.

2.3 Pedoman Keselamatan Operasional

Do not operate the equipment or plug in or unplug the power cord with wet hands; Output must be turned off before connecting or disconnecting wires; do not touch the output terminals, internal components, the load, or the load wiring while the equipment is operating; do not shut down the equipment directly while it is in the output state; turn off the output first before shutting down the equipment; if you notice a strange odor, smoke, unusual noise, or overheating, immediately disconnect the power and do not continue operation.

②	Single-phase parallel connection: Use copper busbars to short-circuit the three output phases to connect high-power single-phase loads.
③	American Standard two-phase, using N/A/B terminals
④	The three phases are independent; you can set parameters for each phase separately and control whether each phase outputs power individually, allowing you to connect three different single-phase loads.
⑤	Three-phase imbalance: Three-phase voltage parameters and phase angles can be set individually; the phase angle range for phases A and B is 110°–130°, the phase angle range for phases A and C is 230°–250°, and the phase angle for phases B and C is automatically matched.
⑥	Standard mode: All three phases are 120° apart, and the same voltage and frequency are set for all three phases.
⑦	Step mode: Allows programmable settings for different output voltages, frequencies, and output durations; automatically switches after output.
⑧	Gradual transition mode: The start and end values for output voltage and frequency, as well as the transition duration, can be programmed; after the output is activated, the voltage and frequency change gradually and uniformly.
⑨	Harmonic Mode: 30 harmonic types to choose from; fundamental voltage and fundamental frequency can be set
⑩	Soft-start mode: You can set the start voltage, start frequency, and start time simultaneously.
⑪	Step Mode: Allows you to set the initial output voltage and frequency, as well as the step voltage, step frequency, and step time. After output begins, the system automatically steps up or down from the initial voltage and frequency.
