Safety regulations and core taboos

Core taboos:

Do not open the lid or connect wires with electricity. Internal capacitors may still be charged after power failure, and it is necessary to wait for at least 5 minutes for discharge;

The control terminal is only allowed to connect to a 24Vdc power supply and is prohibited from connecting to 120Vac (which will permanently damage the circuit board);

When installing an isolation switch on the output side, a shutdown linkage mechanism must be configured, otherwise it may cause equipment failure;

Before resetting the fault, it is necessary to remove the external startup signal to avoid safety accidents caused by accidental restarts.

Potential risk prevention measures

During high-voltage electric shock operation, stand on an insulation pad and operate with one hand; The equipment is well grounded, and the cross-sectional area of the grounding wire is ≥ 1.5mm ²

After discharging the capacitor and cutting off the power, wait for 5 minutes to confirm that the indicator light is off before opening the cover; Do not short-circuit DC bus capacitors

Release static electricity before damaging touch devices with static electricity; Avoid contact with interface pins and sensitive components of the circuit board

Motor damage, correct configuration of motor nameplate parameters and protection parameters, prohibit disabling critical protection functions

Before installation, check that the insulation resistance of the motor/cable is greater than 1M Ω and the measured voltage does not exceed 1000V due to insulation failure

F1 overcurrent motor short circuit, cable short circuit, load mutation inspection motor/cable insulation to reduce load mutation rate

F2 overvoltage deceleration time is too short, and the voltage fluctuation of the power grid prolongs the deceleration time. Install a braking resistor and check the power grid
