| + | [title] Acquiring and installing a new relay |
|---|---|
| + | [* black] The relay must have a 12-volt coil, not 240v or 120v. |
| + | [* black] OpenEVSE has a drop-in replacement relay that likely performs better than the original and fits the JuiceBox mounting studs. See here: [https://store.openevse.com/products/50a-dpst-relay-set|Struthers-Dunn Model - 450BXX50-12] |
| + | [* black] It's a good idea to install the new relay in the reverse orientation of the original JuiceBox relay, so the AC line is on the inactive terminals at rest. This is just preference, doesn't affect operation. |
| + | [* black] Screw the relay wires (usually yellow/white) to the relay coil contacts. |
| + | [* black] Install the AC mains feed into the lower terminals where they fit, while also adding the AC board supply (red/black) small wires on TOP of the AC mains wires (between screw & lug, not between lug & relay). |
| + | [* black] Finally, install the AC output (J1772 cable) lines on the upper terminals where they fit, while also adding the relay sense wires (usually orange and blue) on top of the lugs similar to the AC supply wires. |
