6. Installation and Maintenance

6.1 Installation Guidelines

• Installation Direction: Both horizontal and vertical installation are supported. The maximum operating temperature is limited to 50°C for vertical installation.
• Installation Height: No height restriction for installation.
• Mechanical Size Requirement: The module spacing is 37.5mm, and corresponding reserved space on the DIN rail is required during installation.
• Accessory Installation: The matched left and right end covers must be installed correctly to protect internal bus connections and ensure system stability.
• Protection Specification: With IP20 protection grade, the module shall be installed in a clean control cabinet to avoid dust accumulation and liquid intrusion.

6.2 Wiring Precautions

• The I/O supply voltage is 24 VDC, and the actual contact load shall not exceed the rated 10 A to avoid equipment damage.
• There is no electrical isolation between the bus and the RS232 interface. Common ground processing and anti-interference measures shall be fully considered in system design to prevent signal interference.

6.3 Maintenance and Upgrade

• Hardware upgrade and firmware management can be realized via Automation Studio (V4.3 and above versions).
• Official E-CAD (electrical design drawings) and M-CAD (mechanical design drawings) files are provided to facilitate system integrated design, equipment transformation and daily maintenance.
• As a passive bus base module, it requires no special maintenance. Daily inspection focuses on checking connection firmness and cleaning contact surfaces to keep the module in good operating condition.
