What is the purpose of properly spacing BPUs during installation?

The purpose of properly spacing BPUs (Base Power Units) during installation is primarily to ensure room for maintenance access and to provide adequate air supply. Proper spacing allows technicians to safely and effectively perform routine maintenance, repairs, or inspections on the units. It also facilitates adequate airflow, which is crucial in preventing overheating and ensuring the efficient operation of the units. When BPUs are spaced appropriately, it mitigates the risk of overheating and enhances overall system reliability, which is critical in any power setup.

While other reasons such as following local guidance or allowing for cable installation are important considerations, the primary focus on access for maintenance and air supply directly impacts the operational effectiveness of the BPUs, making this the correct reason for their proper spacing during installation.
