INDUSTRIAL DEPLOYMENT & INSTALLATION GUIDELINES

Successful deployment begins with meticulous site preparation. The installation manual details critical steps to ensure system integrity and long-term performance.
– Pad Preparation: The system requires a level, reinforced concrete pad with a minimum compressive strength of 28 MPa. The pad must include integrated grounding points and cable trenches for power and communication lines.
– Lifting & Positioning: A dedicated lifting plan using certified spreader bars is provided to safely hoist and position the cabinet without stressing structural points.
– Cooling System Commissioning: The liquid cooling circuit must be filled with the specified coolant (water/ethylene glycol mix) and purged of air. Initial startup procedures include verifying flow rates and leak checks.
– Electrical Interconnection: Detailed wiring diagrams guide the connection of AC mains, auxiliary supply, and the DC busbar for parallel expansion. All terminations must be torqued to specified values to prevent hot spots.
– EMS Integration: The system includes a pre-configured Energy Management System (EMS) for intuitive local control and remote monitoring via a secure cloud platform, enabling real-time performance analytics and O&M alerts.
