How to install Minuteman EXR Series Line Interactive Uninterruptible Power Supply

Proper installation ensures optimal performance, maximum battery life, and reliable protection for your equipment. Start by selecting a suitable location—dry, well-ventilated, away from heat sources, water, or excessive dust. The unit should stand on a stable surface with clear space for airflow and any attached external battery packs. Keep cords tidy to prevent tripping hazards and to maintain unobstructed vents on the UPS.

• Unbox and verify contents: Ensure the UPS, power cord, user manual, and any external battery cables or adapters for your SKU are present and undamaged.
• Initial battery conditioning: Connect the UPS to a wall outlet and allow the internal battery to charge for 8–12 hours before applying load; this conditions the battery for accurate runtime readings.
• Load placement: Plug critical devices (servers, NAS, networking gear, workstations) into the UPS’s battery-backed outlets. Non-critical peripherals can be placed on surge-only outlets if provided, optimizing battery use for essential equipment.
• AC power connection: Use the appropriate regional power cord to connect the UPS to a dedicated wall outlet with sufficient amperage. Ensure the outlet matches the UPS input specification and that the circuit can handle the connected load.
• Battery pack integration: If using external battery packs, connect them to the dedicated connectors and follow the unit’s prompts or display indicators to recognize the additional runtime. Perform a test after connection to verify performance.
• Monitoring setup: Connect the USB (or RS-232) cable to a computer and install the included or recommended management software. Configure alert thresholds, automatic shutdown, and notification methods to protect your data and devices during an outage.
• Testing and safety: Run a controlled self-test from the UPS control panel to verify startup sequencing, protection features, and battery health. Confirm proper operation of alarms, indicators, and load transfer behavior.
• Maintenance planning: Schedule regular battery health checks and firmware or software updates when available; maintain ventilation clearance and keep the area free of dust and moisture to maximize longevity.
