3.2.3 Wiring for Power at the Controller

The instrument can be wired for line power by hard-wiring in conduit or by wiring to a power cord. Regardless of the type of wire used, the connections are made at the same terminal. A local disconnect designed to meet local electrical code is required and must be identified for all types of installation. See Figure 3-15and Figure 3-16 on page 14 for suggested local disconnect configurations.

1.Obtain appropriate fittings with NEMA 4X/IP66 environmental rating.

2.Loosen the screws using a phillips-head screwdriver and open the hinged controller cover.

3.Remove the high-voltage barrier (see Figure 3-11 on page 11).

4.Insert the wires through the strain relief fitting or conduit hub located in the right-rear access hole in the bottom of the enclosure. Tighten the strain relief if used, to secure the cord.

5.Properly prepare each wire (Figure 3-13) and insert each wire into the terminal according to Table 3-2. Tug gently after each insertion to ensure the connection is secure.

6.Seal any unused openings in the controller box with conduit opening sealing plugs, see Replacement Parts on page 21.
