Connecting the REPO Port WARNING: If the UPS is to be installed in a computer equipment room, it must be connected to a REPO circuit. The REPO port is designed to meet the requirements stated in National Electrical Code (NFPA 70) Articles 645-10 and 645-11. The REPO port allows power to the UPS output receptacles to be switched off from a remote location. To activate the REPO port: 1. Install a suitable switch at the required remote location. 2. Remove the connector block from the REPO port. Connecting the Ground Bonding Screw The ground bonding screw on the rear of the unit is provided as an attachment point for conductors. Use the ground bonding screw if the rack contains any conductors for the purpose of functional grounding or bonding of ungrounded metal parts. To connect the ground bonding screw: 1. Remove the ground bonding screw. 3. Wire the connector block using stranded, non-shielded wire (AWG #22 - #18, or equivalent). 4. Replace the connector block in the REPO port. 2. Attach the grounding cable and secure the ground bonding screw. IMPORTANT: • The REPO port must meet the requirements of the NFPA Articles 645-10 and 645-11 for a disconnecting means. • The remote switch must be in the Off (open) position to enable power to the output receptacles.
