Installation Instructions
- Ensure secure installation inside the panel for optimal performance.
Installation method:
Fixed installation
Distribution box: Carefully install inside the distribution box to ensure maximum stability and durability.
Vertical installation
Direction: Typically installed vertically, with the operating handle facing upwards for ease of access and operation.
Avoid: Inverted installation is discouraged unless explicitly permitted by the product guidelines.
Connection
Power cord: Securely connect to the input terminal of the circuit breaker (labeled as 'L1', 'L2', 'L3') ensuring reliable power flow.
Load line: Connect to the output terminal (labeled as 'T1', 'T2', 'T3') for smooth load distribution.
Grounding wire: If available, the grounding terminal must be firmly connected to ensure safety.
Distance requirements
Spacing: Maintain ample distance from other devices to facilitate excellent heat dissipation and ease of maintenance.
Reference: For precise spacing guidelines, please consult the product manual.
Safety precautions
Power off operation: Power must be securely turned off during installation to effectively prevent electric shock hazards.
Protective equipment: Ensure the use of insulated gloves and goggles for personal protection.
