Operation &Maintenance
◆Before installation, carefully review the relevant dimensional drawings and mounting instructions, and verify that the nameplate technical specifications meet the requirements.
◆For circuit breakers with a motor operator mechanism, do not remove the motor operator during installation, as it may affect tripping characteristics, After tripping, the motor operator automatically resets the breaker. Closing requires a closing command from the upper- level controller, tripping similarly requires a tripping command. For manual closing opening, set the motor operator switch to "Manual" . If the breaker is in the free trip position, it must be manually reset before performing closing or opening operations.
◆Internal and external accessories of the circuit breaker are preset at the factory. Users should not attempt to adjust or disassemble them.Installation can be done directly.
◆The phase line must be properly connected. Otherwise, internal electronic circuits may not function properly.affecting the protection capability.
◆For breakers equipped with an under voltage release, the release must be supplied with its rated operating voltage before closing is possible.
Transportation& Storage
Transportation
Protect against harmful liquids (such as water, rain, snow, chemical solvents, corrosive liquids, etc.) and avoid mixing with incompatible items; prevent strong impact and compression. Stack according to the packaging orientation instructions; the number of layers must comply with the label on the outer carton.
Storage
◆Ambient Temperature:-10℃to +45℃.
◆Relative Humidity: 90% (at +20℃ambient temperature).
◆The storage location shall be free of dust and conductive particles.
◆No corrosive, flammable, or explosive gases; protected from rain and snow.
◆It shall be dry and well ventilated.
◆Stack according to packaging orientation; the number of layers must not exceed the limit indicated on the outer carton.
Precautions
◆The company is not responsible for warranty claims if terminal damage is caused by improper installation, improper use(non-quality issues),or incorrect wiring.
◆If any issues arise during product use, please contact your local distributor or the company's customer service center.
