Page 6 Fig 1-1. Models description 1.2 Safety Information The use phase Safety class Precaution ◆ Before Do not install the product if the package is with water, or component is missing or broken. Danger Installation ◆ Do not install the product if the label on the package is not identical to that on the inverter.
Page 7 ◆ Do not leave cable strips or screws in the inverter. Risk of inverter damage. Caution ◆ Install the product at the place with less vibration and no direct sunlight. ◆ Consider the installation space for cooling purpose when two or more inverters are placed in the same cabinet.
Page 8 ◆ Wiring Wiring must be performed by authorized and qualified personnel. Risk of danger. Danger ◆ Circuit-breaker should be installed between inverter and the mains. Risk of fire. ◆ Make sure the input power supply has been completely disconnected before wiring. Failure to comply may result in personnel injury and/or equipment damage.
Page 9 ◆ Since all adjustable frequency AC drives from our company has been subjected to hi-pot test Caution before delivery, users are prohibited from implementing such a test on this equipment. Failure to comply may result in equipment damage. ◆ Signal wires should to the best of the possibility be away from main power lines.
Page 10 ◆ After Power-on Do not open the cover after power. Rick of electrical hazard. Danger ◆ Do not touches any input/output terminals of inverter with bare hands. Rick of electrical hazard. ◆ If auto tuning is required, be careful of personal injury when motor is running.
Page 11 capacitor to discharge to a safe value. Failure to comply will result in personal injury. ◆ All pluggable components can be inserted or pulled out only when power has been turned off. ◆ Set and check the parameters again after the AC drive is replaced. General Precautions 1.
Page 12 The AC drive may encounter the mechanical resonance point at some output frequency, which can be avoided by setting the skip frequency. 5. Voltage-sensitive device or capacitor on output side of the AC drive Do not install the capacitor for improving power factor or lightning protection voltage sensitive resistor on the output side of the AC drive because the output of the AC drive is PWM wave.
Page 13 In places where the altitude is above 1000 m and the cooling effect reduces due to thin air, it is necessary to de-rate the AC drive. Fig 1-3. Inverter output current derating and Altitude 10. Protection class DGI900 protection level is IP20 when inverter with keypad.
Page 14 Disposal The electrolytic capacitors on the main circuits and PCB may explode when they are burnt. Poisonous gas is generated when the plastic parts are burnt. Treat them as ordinary industrial waste.

The output frequency of the AC drives decreases as the load increases. You can reduce the workload of the motor under load by decreasing the output frequency for this motor, implementing workload balancing between multiple motors.

Page 228 They have been corrected upon delivery. When you resume the factory values, these parameters will be restored to the factory-corrected values. Generally, you need not perform correction in the applications. Measured voltage indicates the actual output voltage value measured by instruments such as the multimeter. Displayed voltage indicates the voltage display value sampled by the AC drive.
Page 229 Group E0 is user-defined parameter group. You can select the required parameters from all DGI900 functions codes and add them into this group, convenient for view and modification. Group E0 provides a maximum of 32 user-defined parameters. If "uP0.00" is displayed, it indicates that group E0 is null.

Page 237 (1) Reset the inverter after thoroughly investigating the cause of fault and clearing, otherwise, the inverter may be damaged. (2) If it can’t be reseted or fault occurs again after reset, please check the cause of fault, continuous reset may damage inverter. (3) Reset the inverter after waiting for 5min when overload or overheat protection occurs.

Page 240 communication interface, in which The MODBUS standard protocol is used for communication. The inverters can be used as slave connected to the host (such as PLC controller, PC), both of which have the same communication interface and protocol, for the purpose of centralized monitoring of the inverters.
Page 241 The inverter can either used as a host or slave in RS485 network. It can be used for controlling our other inverters as host to achieve multi-level linkage, or controlled by host (PC or PLC) as a slave. The specific communication mode as follows: Inverter is used as slave, in point-to-point communication of master-slave mode.
