2.1 Standar Keselamatan Listrik

Input power supply single-phase AC 220 V ±10 V, 50/60 Hz. It must comply with safety standards and be equipped with a proper protective grounding system, with a protective grounding resistance of ≤4 Ω, to prevent electric shock.

2.2 Standar Keselamatan Lingkungan

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 exhaust vents of the cooling fans. Operating Environment: Temperature 5°C to 35°C, relative humidity ≤65% RH.

2.3 Pedoman Keselamatan Operasional

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

6. Pemecahan Masalah dan Penyelesaian Masalah Umum

Gejala Kesalahan	Kemungkinan penyebab	Prosedur
Tidak dapat menyala	Input power supply failure, blown fuse	Check Input power supply; check the fuse. If it has blown, replace it with a fuse of the same rating. Do not use a fuse with a higher current rating.
The output voltage cannot be continuously adjusted	Gear Shift Issues	If the high-range lock button is not used, the unit operates in automatic mode, with a maximum output voltage of 150 V in low range and a minimum output voltage of 150.1 V in high range.
Alarm during output	The load exceeds the power supply’s capacity	Sebagai contoh, LSP-500VAS has a maximum capacity of 500VA; do not connect loads that exceed the power supply’s capacity.
Kipasnya tidak berputar	Penumpukan debu, kerusakan motor	Matikan daya dan bersihkan debu dari kipas; jika masalah berlanjut, silakan hubungi kami untuk perbaikan atau penggantian kipas.
