Connect the Power
Use 2.5 mm
2
(14 AWG) 75 °C (167 °F) copper wire with 1.2 mm (3/64-in.) insulation to
connect power. Follow these steps for each wire (high side (L1), low side (L2/N), and
ground) to connect power.
1. Turn the screw counterclockwise to open the wiring terminal.
WARNING
If you connect or disconnect wiring while the field-side power is on, an electrical arc can
occur. This could cause an explosion in hazardous location installations. Be sure that
power is removed or the area is nonhazardous before proceeding.
IMPORTANT
The third terminal from the top (between low side and ground) is not used on the 1756
power supplies.
