Installation
NOTE: The pins must be open to keep the UPS running. If the UPS shuts down because the REPO connector
pins are shorted, restart the UPS by re-opening the REPO connector pins and turning on the UPS manually.
Maximum resistance in the shorted loop is 10 ohm.
NOTE: Always test the REPO function before applying your critical load to avoid accidental load loss.
