- Strict Wiring & Installation Prohibitions
- Main power cables and control signal wires must be routed in separate cable trays with a minimum spacing of 30cm; long parallel laying is forbidden.
- Shielded motor cables are recommended; shield shall be grounded only at the control cabinet end.
- Main circuit copper busbars of high-power models shall be tinned and tightened with specified torque to avoid overheating and arcing.
- For multi-pump linked systems, AC contactors shall not be installed on the inverter output side for frequent switching.
- For sites with heavy dust and moisture, clean air duct filters regularly to prevent overheat alarms.
- If long motor cables (>50メートル) 必要です, an output du/dt filter must be installed to suppress peak voltage and protect motor insulation.

Supplementary Key Remarks
- 200V single/3-phase P7 models (P7E / P72 series) are excluded from the above table. This list only covers mainstream industrial 400V 3-phase fan & pump models P7U.
- Model Abbreviation Rule: The trailing digit 0 is often omitted in engineering drawings and procurement documents. 例えば, CIMR-P7U41600 is abbreviated as CIMR-P7U4160.
- Cabinet Classification: Models ≤132kW adopt standard wall-mounted cabinets; models ≥160kW (4160 and above) are large floor-standing cabinets equipped with independent high-power cooling fans.
- Distinction of output versions at the same power rating:
Standard built-in braking transistor; high-power models 4160 and above require an external braking unit + braking resistor to implement dynamic braking during deceleration.
