
packing water, parts missing or damaged parts, please do not install!

Packaging logo and physical name does not match, please do not
install!

Handling should be light lift, otherwise there is the danger of damage
to equipment!

Do not use damaged drive or missing drive. Risk of injury!

Do not touch the control system components by hand, or there is the
danger of electrostatic damage!

Please install the flame retardant objects such as metal, away from
combustibles, or may cause a fire!

Do not allow lead wires or screws to fall into the drive, otherwise the
drive may be damaged!

Install the drive in a place where there is less vibration and direct
sunlight.

Drive placed in airtight cabinet or confined space, please note the
installation of space to ensure the cooling effect.

You must follow the guidance of this manual and be used by qualified
electrical engineers. Otherwise, unexpected danger may occur!

There must be a circuit breaker between the drive and the power
supply, otherwise a fire may occur!

Make sure the power supply is in zero-energy state before wiring,
otherwise there is danger of electric shock!

Please follow the standard to the drive properly grounded, otherwise
there is the risk of electric shock!

Never connect input power to the drive's output terminals (U, V, W).
Note that the terminal markings, do not take the wrong line! Otherwise
it will cause damage to the drive!

Never connect the braking resistor directly to the DC bus +, - terminals.
Otherwise it will cause a fire!

Refer to the manual's recommendations for the wire diameter used.
Otherwise it may happen accident!

Do not disassemble the connecting cable inside the driver. Otherwise,
the internal of the servo driver may be damaged.

Make sure the voltage level of the input power is the same as the rated
voltage of the driver. Check if the wiring position of the power input
terminals (R, S, T) and output terminals (U, V, W) is correct; Of the
external circuit is short-circuited, the connection is tightened, or cause
