Product Installation Diagram
Tips
- When installing this product, the horizontal lines between cabinets should be securely and reliably connected.
- The door of this product features an interlocking mechanism with the main switch, meaning the door can only be opened when the power is off. The other side panels of this product are secured with screws and do not have an interlocking function with the main switch. Therefore, users must ensure that the power is disconnected before removing the side panels for maintenance.
- Non-professionals should not attempt to open the cabinet for maintenance or repair.
Frequently Asked Questions
What standards does this switchgear series comply with?
This product complies with international standards IEC 439 and NEMA ICS 2-322, as well as the national standard GB 7251-2005 for "Low-Voltage Complete Switchgear" and the professional standard ZBK 36001 for "Low-Voltage Withdrawable Complete Switchgear."
What are the environmental temperature requirements for installation?
The ambient air temperature must be between -50℃ and +40℃. Additionally, the average temperature within any 24-hour period should not exceed +35℃.
Can the cabinet doors be opened while the system is powered on?
No. The cabinet door is equipped with an safety interlocking mechanism linked to the main switch, ensuring the door can only be opened when the power is completely turned off.
What is the protection level and operation mode of this switch cabinet?
The cabinet features an IP40 level of protection. It supports three operation modes: On the Spot, In the Distance, and Automatically.
What should be done if the installation site conditions do not meet the standard specifications?
If your specific application conditions exceed the standard limits (such as elevation over 2000m or extreme environmental factors), please communicate your requirements to our company when placing your order to negotiate a customized solution.
