Connecting the Power Wires
WARNING: All electrical components must meet applicable
national and local electrical codes including installation by
qualified personnel. These codes may require a means in the fixed
wiring of disconnecting AC power having a contact separation of
at least 0.120" (3mm) in the line and neutral poles. The wire used
for connection to the controller must have insulation rated at
105°C minimum. Do not connect the controller to one phase of a
3-phase power source. Ensure the AC power source is OFF prior
to connecting to the controller.
Connecting an Earth Ground Source
Caution: Warranty may be void if the controller is not properly
grounded to an earth ground device.
!
1. Install a copper-clad ground device; i.e., 8’ (2,5m) ground rod into
well moistened soil. The top of the rod buied at least 12” (30,5cm)
below grade.
2. Using a Cad-weld
TM
(or equivalent) attachment method, connect a
6 AWG (10mm
2
) solid copper wire to the ground device and route
to the controller in the most direct path. (Wire bends should be
minimal and not be less than 8” (20,3cm) in radius).
3. Route ground wire through cabinet base using 1/4” (6mm) access
hole provided.
