Safety tips for equipment wiring
Danger
● It's strictly prohibited for non-professional personnel to perform equipment installation, wiring, maintenance, inspection or part replacement!
● Before wiring, please power off all devices. As the power-off devices have built-in capacitors which have residual voltage, please wait at least the period specified in the Alarm label before wiring. Measure DC voltage of main loop and confirm that it's under the safe voltage, otherwise there is a risk of electric shock.
● Please perform wiring operation, remove the cover of product, or touch circuit board when it powers off. Otherwise, there is a risk of electric shock.
● Please ensure that devices and products are properly grounded; Otherwise, electric shocks might occur.
Alarm
● It's strictly prohibited to connect the input power to output of device or product; Otherwise, device might be damaged or even it starts a fire.
● When drive is connected to the motor, please ensure that the phase sequence of product and motor terminals are accurate and consistent so as to avoid reversing motor rotation.
● Cables used for wiring must meet the requirement on diameters and shielding, correspondingly. Shielding layer of shielded cables shall be reliably grounded at single end.
● Tighten terminal screws according to tightening torque specified in the manual. Insufficient or excessive tightening torque may cause overheating or damage to the connection, and even start a fire.
● After wiring operation ends, ensure that all cables are properly connected and no screw, gasket or exposed wire are found inside the product. Otherwise, there might be a risk of electric shock or product damage.
Attention
● To avoid damage to the equipment or built-in circuit of product, follow the steps specified in ESD preventive measures and wear a wrist strap to handle wiring operation.
● For wiring of control loop, use double-stranded shielding cables to connect the shielding layer to grounding terminal of the product. Otherwise, it might cause abnormal actions of the product.
