how to install Eaton Tripp Lite Series ±120VDC External Battery Cabinet for Select 10-30K S3M-Series 3-Phase UPS

• Verify compatibility: Confirm that your UPS is within the SmartOnline S3M-Series 3-Phase family and that the UPS model supports external ±120VDC battery configurations. Review the user manual or consult technical support if you are unsure about the exact SKU compatibility.
• Power down and prepare: Before installation, power down the UPS and disconnect main input sources to ensure a safe work environment. Confirm that any battery replacement or extension work complies with your facility’s safety protocols and local regulations.
• Position the cabinet: Place the external battery cabinet in a secure, well-ventilated area near the UPS. Ensure there is adequate clearance for maintenance access and cable routing, and follow any manufacturer-recommended mounting or stand requirements if floor mounting or rack mounting is used.
• Connect the DC link: Use the supplied DC interconnect cables to connect the external battery cabinet to the UPS DC input/output terminals designated for external battery banks. Follow the wiring diagram in the installation guide precisely to avoid incorrect polarity or loose connections.
• Secure and inspect: After wiring, secure all connections with the appropriate fasteners, verify cable routing to prevent strain or interference, and inspect physically for signs of damage or wear. Check for proper ventilation signs and ensure there are no obstructed vents in the cabinet or surrounding area.
• Configure UPS settings: Power up the UPS and access its configuration interface to recognize the external battery bank. Enable external battery monitoring if available, and set runtime expectations according to the load profile and desired uptime targets.
• Test and validate: Run a controlled battery discharge or runtime test to validate that the external cabinet provides the expected extension of runtime under your typical load. Monitor voltage, current, and temperature readings during the test to confirm stable operation.
• Documentation and maintenance: Record serial numbers, installation dates, and maintenance windows. Establish a regular inspection and battery health check schedule to ensure long-term reliability and uptime performance.

Frequently asked questions

• Q: What is the primary benefit of using an external ±120VDC battery cabinet with S3M-Series 3-Phase UPS?
