2.1 Standar Keselamatan Listrik

Input power supply single-phase AC 110 V/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.

Note: The rear panel of the LSP series power supplies features an input voltage selector switch. See Section 3.2. Please take note!

2.2 Environmental Safety Standards

For indoor use only; avoid direct sunlight. Place on a sturdy, stable surface to prevent excessive vibration. 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 clearance 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% RH.

2.3 Pedoman Keselamatan Operasional

Do not operate the equipment or plug in/unplug the power cord with wet hands; the output must be turned off before connecting or disconnecting wires; allow the unit to warm up for at least 10 minutes after powering on before enabling the output; Do not touch the output terminals, internal components, the load, or load wiring while the equipment is operating; allow at least 3 minutes between powering on and off to prevent damage from power surges; do not shut down the equipment directly while it is in output mode; first disconnect the output before shutting down; if you notice an unusual odor, smoke, abnormal noise, or overheating, immediately disconnect the power and do not continue operation.

Tidak dapat menyala	Kerusakan sakelar pemilih tegangan input, sekering putus.	Periksa sakelar pemilih tegangan input; matikan daya, hilangkan korsleting atau kelebihan beban pada output, ganti sekering dengan yang memiliki nilai yang sama, dan jangan menambah nilai arus.
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.
Kode kesalahan 02 di pojok kanan bawah layar.	In the event of an output short circuit, current overload, or power overload, the power supply will automatically cut off the output to protect itself.	Please turn off the LSP power supply, check the wiring, and resolve any output short circuits before turning it back on; if the load current or power exceeds the power supply’s upper limit, you will need to purchase a larger AC power supply.
Kode kesalahan 01 di pojok kanan bawah layar.	Sekring putus.	Please turn off the LSP power supply and unplug the power cord. Check all fuses on the rear panel of the power supply and replace them with fuses of the same rating. Do not use fuses with a higher current rating.
