Overview Emergency Power Off System The Emer gency Power Off (EPO) System consists of one or more wall-mounted, push-button EPO boxes. Each EPO box provides a single point of equipment shutdown for up to eight APC devices and one third-party device (such as an upstream breaker), using Normally Open (NO) contact closure connections. An EPO box can b[...]

Installation Prepare the EPO 1. Open the EPO System box by removing the screws on the side. Keep the screws for use after the system is installed. The box will not close securely without the screws in place. 2. Mount the system in a readily-accessible area, on a wall near the principal entrance doors, according to NEC Articles 645.10 and 645.1 1, I[...]

3. Install an appropriate tting with a lock-nut for each knockout used. 4. Connect conduits to the ttings. Note: If not using conduits, run the cables through the knockout directly .

2. Run the conduits (or cables) from the connected devices to the junction or switch box. If using conduits, it will contain all wiring from the connected devices and all cascading cables. Remove the knockouts required for installation. Note: When planning conduit requirements, consider that two cascading cables will t in 13 mm (½ in) conduits [...]

7. Reinforce the EPO box with 6 mm (¼ in) screws in the corner mounting holes. Note: The top two 6 mm (¼ in) mounting holes may be blocked by some junction boxes. In this instance, use only the bottom two 6 mm (¼ in) mounting holes for reinforcement. Connect Devices to the EPO Box Connect APC devices to terminals 1–8. Connect an auxiliary devi[...]

5. Connect a suitable ground or PE wire to the #8-32 ground stud in the lower left corner of the EPO box. Mount Additional EPO Boxes There are two alternatives for wiring additional EPO boxes. Either cascade the boxes only to wire devices to one box (see “Cascade Multiple EPO Boxes“ ), or wire devices directly to each EPO box (see “Direct W i[...]

APC APC APC APC APC APC APC APC Note: The recommended maximum total distance of wire, to run per circuit is 300 m (1000 ft). Cascade the APC Devices with CA T -5 Cables Connect the CA T -5 cables to the jacks inside the EPO box. Each cable can support up to four APC device wire pairs. Follow these guidelines when connecting CA T -5 cables: • Use [...]

Cascade the Auxiliary Device with Wire Pairs 1. After wires are run from auxiliary device (1) to terminal block position 9, run a second set of wires (2) from terminal block position 9 on the rst EPO box to terminal block position 9 on the second EPO box. 2. Continue until all boxes are connected. (See the diagram in “Cascade Multiple EPO Boxe[...]

Note: If an APC FM Series Precision Air Conditioning System connected to the EPO box, pressing the check point will shut off functionality to the unit, but the unit will still be powered. B. After verifying the wiring, close the system box, making sure not to pin wires or disturb connections, and secure with the screws, previously removed when open[...]

Operation Engage the System 1. Lift the shield on any of the installed EPO boxes and press the button. A red ag will drop down from the box, providing an easy visual mark as to which EPO box in your room has been activated. Reset the EPO System 1. Pull the button towards you (1) and push the ag up until it catches (2). Pulling the button does[...]

Reset the Equipment Apply power to the devices according to the procedures for each device. Note: Refer to the operation manual included with each device for specic instructions on how to apply power to the device. 990–161 1C-001 Emergency Power Off System Installation and Operation 15[...]
