Safety information and precautions
1.1.3 During wiring:
Danger
●
Please observe the manual guidance and construct by professional electric engineering staff, otherwise
danger may occur!
●
Breaker should separate frequency convertor and power, otherwise fire may occur!
●
Please ensure that power is at zero-energy state before wiring, otherwise electric shock may occur!
●
Please keep correct earthing of convertor as per standards, otherwise electric shock may occur!
Danger
●
Do not connect input power to output terminal (U, V, W) on frequency convertor. Pay attention to
marking on wiring terminal and do not wire wrongly, otherwise driver may be damaged!
●
Ensure that all wirings conform to EMC requirements and regional safety standard. All wire diameters
refer to suggestions in manual, otherwise accident may occur!
●
Do not connect brake resistor directly between DC bus (+) (-) terminals, otherwise fire may occur!
●
Encoder shall use shielded wire single and ensure reliable earthing for terminal of shielding layer!
1.1.4 Before electrifying:
Caution
●
Please confirm the consistence between voltage class of input power and rated voltage class of
frequency convertor; correctness of wiring positions of power input terminal (R, S, T) and output
terminals (U, V, W). Check if any short circuit of peripheral circuit connecting to driver and if wiring
circuit is tightened, otherwise driver may be damaged!
●
Neither part of frequency convertor needs withstand voltage test as the product has been tested!
Danger
●
Electrify frequency convertor after covering cover plate, otherwise electric shock may occur!
●
Wiring of all periphery accessories shall comply with manual guidance and keep correct wiring as per
circuit connection method in manual, otherwise accident may occur!
1.1.5 After electrifying:
Danger
●
Do not open cover plate after electrifying, otherwise electric shock may occur!
●
Do not touch driver or peripheral circuit with wet hands, otherwise electric shock may occur!
●
Do not touch any input or output terminal of frequency convertor, otherwise electric shock may occur!
●
When firstly electrifying, frequency convertor will conduct security detection of external strong-
current loop, and do not touch U, V, W wiring terminal of driver or wiring terminal of motor,
otherwise electric shock may occur!
