Receiving and unboxing inspection

1. Safety precautions

It is prohibited to transport equipment through the front cover or terminal cover to avoid damage caused by the main body falling;

When handling equipment and circuit boards, it is necessary to follow the electrostatic discharge (ESD) process to prevent circuit damage.

2. Model and nameplate verification

Key information on the nameplate: model (such as CIMR-RU2A0073AAA), rated capacity, input/output specifications, software version, serial number, and place of origin (Japan);

Model interpretation: Taking "CIMR-RU2A0073AAA" as an example, "RU" represents the R1000 series, "2A" is the 200V level, "0073" is the rated output capacity code, and "AAA" is the standard configuration.

3. Classification of enclosure types

IP20/UL Type 1: Suitable for indoor wall mounted or control cabinet installation, retaining IP20 protection even after removing the top protective cover;

IP00/Open Type: It needs to be installed inside a protective panel, without additional shell protection, and relies on external environmental isolation.

Mechanical Installation: Environmental Requirements and Operating Standards

1. Installation environment requirements

Specific requirements for environmental dimensions: Remarks

Temperature IP00 model: -10~+50 ℃; IP20 model: -10~+40 ℃ overheating requires capacity reduction to avoid severe temperature fluctuations

Humidity ≤ 95% RH, no condensation to prevent moisture and short circuit of the circuit board

Altitude ≤ 1000 meters (without capacity reduction); 1000~3000 meters: For every 100 meters increase, the capacity is reduced by 1%. At high altitudes, the heat dissipation capacity needs to be evaluated

Vibration low-power models (2A03P5~2A0053, etc.): 10-20Hz (9.8m/s ²), 20-55Hz (5.9m/s ²); High power models (2A0073~2A0105, etc.): 20~55Hz (2.0m/s ²) Avoid direct contact with vibration sources

The surrounding environment should be free of dust, oil mist, metal debris, corrosive gases, and direct sunlight. Installation on flammable surfaces or placement of flammable materials is prohibited

2. Installation method and spacing requirements

Installation direction: Only supports vertical installation. Tilting can cause poor heat dissipation and damage to internal components.

Single installation spacing:

Up and down direction: at least 120mm (heat dissipation space);

Left and right direction: at least 30mm (wiring and heat dissipation);

Rear: It should be tightly attached to the enclosed surface to avoid the dispersion of cooling airflow.

Side by side installation (with drive):

Ordinary side by side: minimum spacing of 50mm, top aligned;

Tightly side by side (only for low-power models 2A03P5~2A0028, etc.): spacing of 2mm, parameter L8-35=1 needs to be set, while considering capacity reduction.

3. Precautions for lifting and protection

High power models (2A0073, 2A0105, etc.) are equipped with lifting rings and are only used for temporary installation. Long term suspension is prohibited;

When lifting vertically, it is necessary to first fix the front cover, terminal block and other components. The vibration/impact during suspension should not exceed 1.96m/s ², and flipping or leaving unattended is prohibited.

Electrical installation: wiring specifications and safety requirements

1. Main circuit wiring (prevention and control of core risk points)

Terminal differentiation:

Input terminals (R/L1, S/L2, T/L3): connected to three-phase power supply, matched with equipment voltage level (200V level connected to 200~240V, 400V level connected to 380~480V);

Output terminals (+, -): Connect to the DC bus of the driver, be careful not to reverse the positive and negative poles;

Voltage detection terminals (r1/11, l/21, t1/31): detect the phase sequence and voltage of the input power supply, and take power from the primary side of the power coordination reactor.

Wiring requirements:

Wire specifications: Select according to the rated current of the model. For example, 2A03P5 uses 14AWG (American standard) or 3.5mm ² (European standard) wire, 4A0300 uses 300kcmil wire, and circular crimping terminals are required;

Tightening torque: M4 screws 2.1~2.3N · m, M8 screws 5.4~6.0N · m, excessive tightening may damage the terminals;

Grounding: Independently grounded, not sharing grounding wire with high current equipment such as welding machines; Grounding resistance of 200V level ≤ 100 Ω, 400V level ≤ 10 Ω.
