2. Tighten the connectors to a torque of 1.77 to 2.16 Nm. (For conduits, use a tightening torque of 0.78 to 0.88 Nm.)

The case may be damaged if the connectors are tightened excessively.

3. If using a 1/2-14NPT conduit, apply sealing tape to the connector conduit opening to conform to IP67.

4. For 3-conduit connections, use the enclosed cap screws on the unused conduit openings and tighten to a torque of 1.27 to 1.67 Nm.
