6. Installation and Maintenance
Installation Location
Typically installed in the electrical cabinet between the inverter and the motor.
Installation Steps
- Power Off Operation: Before installation or replacement, the power must be cut off, and the Lockout/Tagout procedure must be followed.
- Remove Old Part: Dismantle the original snubber PCB.
- Install New Part: Install the 1336-SN-SP10A PCB in place and connect the corresponding cables and terminals.
- Inspection and Testing: Check if the wiring is secure and conduct a power-on test to verify the operation status of the inverter.
Maintenance Recommendations
- Regular Inspection: Check the appearance of the PCB for signs of burning, discoloration or corrosion.
- Environmental Requirements: Ensure the installation environment is dry, avoiding high temperature and humidity to prevent affecting its IP67 protection performance.
- Replacement Cycle: Depending on the equipment usage frequency and working environment, it is generally recommended to inspect it every 2-3 years as part of routine maintenance.
