To ensure a successful UPS deployment, pre-sales confirmation focuses on accurately matching your needs and avoiding installation risks. Start by defining your load list, backup time, installation scenario, and power environment. Then proceed with UPS sizing (capacity calculation, type matching, battery configuration, specification verification), followed by a thorough site environment check (space, floor loading, temperature/humidity/dust, cabling, grounding, isolation). Confirm the technical solution, service warranty, and delivery schedule, and finally review all contract details including model, quantity, unit price, total price, payment terms, delivery time, after-sales terms, and shipping arrangement. This structured approach guarantees a tailored, reliable, and risk-free power protection solution.
