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 3-15 and
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.
