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 device to terminal 9. Connect only one 0.10–0.75 mm² (24–18 AWG) wire pair to each terminal block.

1.Attach EPO circuits to each device according to the specific instructions for that device. Use

the Normally Open (NO) contact option.

2. Run a suitable 0.10–0.75 mm² (24–18 AWG) wire from the devices to terminals 1–8 on the EPO box terminal block. If you are using conduits, run the wires through the conduits to the terminal(s). Make the connections to the terminal block in numerical order (terminal 1, and then terminal 2, etc.).

3. Run a suitable 0.25–0.10 mm² (22–18 AWG) wire from the contact closure points for any auxiliary device to terminal 9 on the EPO box terminal block. If you are using conduits, run the wires through the conduits to the terminal.

Note: The auxiliary circuit is rated 1A at 48 VDC/240 VAC.

4.If necessary, secure the wires inside the box using the releasable wire ties (provided).
