1. Connect the dc common terminal on the power supply to
the dc common (-) terminal on D8 TB2.
2. Connect the positive terminal on the power supply to the
dc positive (+) terminal on D8 TB2.
3. If using an isolated dc output or another power supply to
power the loads, connect the dc common of the supply
powering the loads to the dc common of the supply pow-
ering the controller.
4. Use the ground connector on TB2 for chassis ground.
This terminal is connected to the D8 chassis and must be
connected to earth ground.
5. Connect 120/240 Vac power to the power supply.
NOTE! Connect the dc common of the power supply
used for loads to the dc common of the sup-
ply powering the controller. If the supplies
are not referenced to one another, the con-
troller’s outputs will not be able to switch the
loads.
NOTE! When making screw terminal connections,
tighten to 4.5 to 5.4 in.-lb. (0.5 to 0.6 Nm).
CAUTION! Without proper grounding, the D8 may not
operate properly or may be damaged.
