V. Installation and Maintenance Guidelines

(I) Installation Specifications

Mechanical Installation

When using rail or backplane installation, ensure that the tightening torque of the fixing bolts complies with the specifications (recommended to be 1.5-2.0N·m), and reserve a gap of ≥10mm between modules to ensure smooth heat dissipation.
The installation location should be far away from interference sources and heat sources such as high-power frequency converters and heaters (distance ≥80cm). Install shock-absorbing gaskets next to equipment with severe vibration to avoid mechanical stress damaging internal components.

Electrical Wiring

Use copper core cables (cross-sectional area ≥1.5mm²) for the power supply line, and configure an independent air switch (rated current ≥10A). The pressing force of the terminal block should be moderate to prevent heat generation due to poor contact.
Use shielded twisted-pair cables for control signal cables, and ground the shield layer at one end (grounding resistance ≤4Ω). Avoid parallel routing with power cables; when crossing, keep a 90° vertical angle to reduce interference.
Before wiring, disconnect the system power supply, strictly distinguish between the positive and negative poles of the power supply and the input and output terminals, to avoid module burnout due to reverse connection.

(II) Configuration and Debugging

Parameter Configuration

Enter the configuration interface through GE's dedicated programming software or HMI panel, and set parameters such as output frequency, response threshold, and protection parameters according to control requirements. For example, in the motor control scenario, set the overcurrent protection threshold to 1.2 times the rated current.
For multi-module linkage systems, it is necessary to configure communication parameters and data interaction protocols to ensure smooth transmission of commands and status signals between modules.

Debugging Process

No-Load Debugging: Disconnect the load connection, check the status of the module's operation indicator light after power-on, test whether the output response is normal through analog signals, and connect the load only after confirming that there is no abnormality.
Load Debugging: Gradually load to the rated working condition, monitor parameters such as module temperature and output accuracy. For example, in the 50kHz output state, the measured actual output frequency deviation should be ≤±0.1kHz.
Linkage Debugging: Test the coordinated operation effect of multiple equipment to ensure that functions such as process connection and parameter linkage meet the requirements of the production process.
