Wiring Guidelines
Wiring to the Power Supply
Connect the AC or DC power source input wiring to the power supply as shown. The power
supply terminals can accept up to 14 AWG solid or stranded wire. Do not overtighten the
terminal screws; the recommended torque is 7 to 9 inch-pounds (0.882 to 1.02 Nm).
WARNING: Once the power wiring is connected, secure the terminal block cover in the closed position.
When the cover is open there is a risk of electrical shock if you accidentally touch the connection
terminals or power wiring.
Grounding
A good common ground reference (earth ground) is essential for proper operation of the
Productivity3000 system. One side of all control circuits, power circuits and the ground lead
must be properly connected to earth ground by either installing a ground rod in close proximity
to the enclosure or by connecting to the incoming power system ground. There must be a
single-point ground (i.e. copper bus bar) for all devices in the enclosure that require an
earth ground.
