However, transfersbetween Normal mode and Bypass mode are available through thefront panel.Two REPO/ROO positions may be used: normally-open ornormally-closed. The pins on the normally-open REPO connector are notconnected together. When this connection is closed: For REPO, the logic circuitry completely shuts down the UPS, thuspreventing the power from supplying the load. For ROO, a remote on signal energizes the load, and opening theconnection sends a remote off signal that de-energizes the load.NOTE To restart the UPS, return the REPO terminal to its normal deactivated state, thenuse the front panel to return the UPS to Normal mode.NOTE Disconnect the load when changing the active state of the ROO contact. The loadwill energize or de-energize as soon as the state is changed, depending on whether there is ajumper installed.C A U T I O N The REPO must not be connected to any utility connected circuits. Reinforced insulationto the utility is required. The REPO switch must have a minimum rating of 24 Vdc and20 mA. To ensure the UPS stops supplying power to the load during any mode of operation, theinput power must be disconnected from the UPS when the emergency power-off functionis activated. When REPO is activated for a UPS with line-to-line 208V input, the output receptacleswill have 120V neutral (L2) to ground.REPO/ROO ConnectionsWire Function Terminal Wire Size Rating Suggested Wire SizeREPO/ROO L1 0.82–0.33 mm2(18–22 AWG) 0.82 mm2 (18 AWG)L2
