Only qualified service personnel (such as a licensed electrician) should perform the hardwired installation.

The REPO switch is a customer-supplied switch that can disconnect UPS output voltage from your protected equipment. If you are using a REPO switch, you need a junction box, external wiring, and a switch with the following specifications:

SThe switch should be a wall-mounted, momentary-contact, normally open, pushbutton switch.

SMinimum ratings of 240 Vac and 35 mA.

SWire should be 18 AWG (0.75 mm2) minimum.

SThe black and white REPO wires are at high-voltage potential (240V). Refer to your local electrical code for proper installation of the high-voltage REPO wires.

STo ensure the UPS stops supplying power to the load during any mode of operation, the input power must be disconnected from the UPS when the emergency power-off function is activated.

1.Place the conduit through the access hole on the junction box (see Figure 6). Connect the exposed conduit wires to the corresponding compression terminals (see the following table). Tighten the compression terminals with a screwdriver.

2.Pivot the REPO receptacle guard out of the way, plug the REPO plug/receptacle PPU connector into the REPO receptacle on the PPU rear panel and twist the connector in place (see Figure 4 on page 26).
