Instructions

Instructions for Use

Transport in original factory packaging; handle carefully.
Store in dry, non – corrosive gas indoor environment.

User acceptance inspection

Check nameplate model matches purchased product before use.
Capacity test: Conduct as per 4.2, using instruments with ≤2% relative error.
Withstand voltage test: Apply 75% of the voltage specified in 4.3.

Installation and operation

Install indoors, for use below 2000m altitude.
Ambient temperature -25~+50℃,humidity <85%; low-temperature version (-40~+50℃) available on request.
Installation site: avoid direct sunlight, rain,excessive dust and severe vibration; spacing >30mm; ensure good ventilation and heat dissipation in high summer temperatures.
Before installation,consider voltage rise after capacitor input to prevent long-term operation under over voltage; check voltage waveform and network characteristics; take measures to limit harmonics if harmonic sources exist.
When paralleled with induction motor, capacitor current <90% of motor no-load current.
Use flexible copper wires for line and grounding terminals,ensure good contact; check terminals regularly to prevent damage.
Interval between disconnection and reconnection >3min (self-discharge time) to avoid over voltage damage.

Ordering instructions

Users must provide product rated voltage,rated capacitance, number of phases, and other parameters.
Users should try their best to provide some characteristics of the place of use.
