|
| ! | WARNING! Read Safety Warning, on page 1, before using this control. |
|
|
|
| Disconnect the AC line before wiring. | |

Note: To avoid erratic operation, do not bundle AC line and motor wires with wires from sig- nal following, Start/Stop Switch or any other signal wires. Use shielded cables on all signal wiring over 12” (30cm). Shield should be Earth grounded on the control side only. Wire the control in accordance with the National Electrical Code requirements and other codes that may apply to your area. See Table 3 and Figure 4, on page 6.
Be sure to properly fuse each AC line conductor that is not at ground potential. Do not fuse neu- tral or grounded conductors. See Section VII, on page 10. A separate AC line switch or con- tactor must be wired as a disconnect so that each ungrounded conductor is opened. A Power On/Off Switch may be used in lieu of, or in addition to, the Start/Stop Switch. The switch can be wired for single pole or double pole operation, as required.
To maintain the watertight integrity of the control, be sure to use suitable watertight connec- tors and wiring which are appropriate for the application. Two 7/8” (22.2mm) knockout holes are provided for standard 1/2” knockout connectors (not supplied) for wiring. A watertight plug is provided if only one knockout is required.
The enclosure is designed with a hinged case so that when the front cover is open, all wiring stays intact. To open the cover, the four screws must be loosened so they are no longer engaged in the case bottom. After mounting and wiring, close the cover making sure that the wires do not get caught or crimped as the cover is closed. Tighten all four cover screws so that the gasket is slightly compressed. Do not over tighten.
