6. Installation and Maintenance

Installation Method

• Vertical Installation: Vertical installation is usually adopted, which requires good ventilation and avoids direct sunlight.
• Heat Dissipation Space: Reserve at least 100mm of heat dissipation space on the top, bottom, left and right during installation to prevent overheating.

Wiring Requirements

• Main Circuit: Connect L1/L2/L3 to the input terminal, U/V/W to the output terminal, and PE as the ground wire.
• Control Circuit: Provides 24V DC power supply, including Digital Input/Output (DI/DO) and Analog Input/Output (AI/AO).
• Braking Resistor: If the load requires rapid braking, an external braking unit (e.g., BTV series) is required.

Environmental Adaptability

• Temperature Control: The operating temperature range is -10°C to +50°C, and derating is required according to the ambient temperature when mounted on DIN rails.
• Protection Class: The standard protection class is IP21; for use in humid or dusty environments, please select the IP54 or IP65 version.
