For non-conduit installations, plug the detachable AC line cord into the receptacle on the rear of the control unit. Plug the
other end of the line cord into a properly grounded 120 volt AC outlet.
For installations where it is required to run the AC input wiring in conduit, perform the following.
1.Ensure the AC line cord is unplugged and remove the AC inlet receptacle wiring from TB1-N, TB1-L1, TB1-EARTH GROUND (see
figure 2)
2. Remove the mounting hardware from the AC inlet receptacle and remove it from the rear of the control unit.
3. Install the conduit adapter plate (supplied) in the hole where the AC inlet receptacle was removed. (see Figure 2)
4. Install the AC input wiring (0.8mm
2 (18 AWG) minimum) through the conduit adapter plate using conduit and wire to TB1 as follows.
Hot/Line to TB1-L1
Neutral/Common to TB1-N
Ground to TB1-EARTH GROUND
NOTE
When using conduit to route the AC input wiring to the control unit, the last several feet of conduit attached to the control unit should be
of a flexible type, such that the control unit chassis can be slid out of its enclosure for testing and set-up purposes.
