UM353-1
Installation

Power input to a Moore 353 should be routed through a
clearly labeled circuit breaker, fuse or on-off switch that is
located near the controller and is accessible by the
operator. The protective device should be located in a
non-explosive atmosphere unless suitable for use in an
explosive atmosphere. This type of wiring is shown in
Figure 8-27. It will permit removal of controller power
without affecting the on-line status of adjacent controllers.
Where separate wiring is not required, power input wiring
can daisy chain together a series of controllers. Here, each
controller, except for the last controller on the daisy chain,
will have two wires (18 AWG recommended) inserted in
terminal H and in terminal N. If a larger gauge is to be
used, the two wires can be inserted in a crimp-on
connector and the connector inserted in the terminal, for a
more secure installation. Daisy chained wiring is shown
in Figure 8-28. Perform the following steps at H, N, and
G terminals at each involved controller.

FIGURE 8-28 Daisy Chained Power Wiring
1. Strip ground wire(s) 3/8" (10 mm) to 1/2" (13 mm). Clamp the ground wire(s) under the green, square pressure
plate and ground screw (case/safety ground) at top center of each rear terminal area. Tighten the ground screw
to 20 in. lbs.
2. Remove 1/4" (6 mm) to 5/16" (8 mm) from each Hot and Neutral wire to be inserted in a terminal or crimp-on
connector.
3. Crimp-On Connector only - Insert the wires into the crimp-on connector until the wires are visible at the pin
end of the connector. Use a standard electrical connector crimp tool to crimp the connection. Be certain that
both power input wires are fully inserted in the connector before crimping.
4. Loosen the terminal screw using a straight blade screwdriver with a 1/8" (3 mm) blade width.
5. Insert the striped wire or crimp-on connector pin into the terminal and tighten the screw to 5 in. lbs.
