Precautions for Wiring 3.1
Safety Requirements 3.1.1
The following requirements should be strictly followed when wiring.
Warning

Do not touch the internal components of the servo drive; otherwise, there are chances of electric shock.

When the servo is powered on, no one is allowed to enter the range of its mechanical movement to prevent any
possible personal injury or deaths.
Note

Only trained and authorized qualified engineers can perform the external wiring of the servo drive.

Check the voltage class of the servo drive carefully before powering it on. Failure to do so may lead to personal
injury or device damages.

Only reliably power off all the power to the system and wait at least 10 minutes can the servo drive housing be
opened.

Make sure that the rated input voltage of the servo drive is consistent with the AC supply voltage before use.

The servo drive has passed the voltage withstanding test before delivery, so the user should not perform this
test again.

Do not connect the power supply with the motor power output terminals U, V, W

Both the servo drive and motor must be reliably grounded for safety purposes.

For easier input side overcurrent protection and maintenance at outage, the servo drive should be connected to
the power supply through an air switch or fuse switch.

Except for the X1 terminal, it is strictly forbidden to connect the power supply input terminal to other terminals.
Otherwise, the product will be damaged.

The input voltage of all terminals should not fall out of the allowed range.

The maximum output current for the motor brake control output line connector is 1A. If the current carried by
the brake control is out of the allowed range, use an external relay to get the current back into the allowed
range.

Make sure the wiring sequence is correct, the connection is secure and the insulation is reliable before power
on. Otherwise, the product can be damaged.
