ROC827 Instruction Manual

3.4Installing a Power Input Module

To install the Power Input module:

Caution	Failure to exercise proper electrostatic discharge precautions, such as
	wearing a grounded wrist strap may reset the processor or damage
	electronic components, resulting in interrupted operations.

When working on units located in a hazardous area (where explosive gases may be present), make sure the area is in a non-hazardous state before performing procedures. Performing these procedures in a hazardous area could result in personal injury or property damage.

Note: Remove the plastic module cover and wire channel cover, if present.

1.Slide the Power Input module into the slot.

2.Press the module firmly into the slot. Make sure the connectors at the back of the Power Input module fit into the connectors on the backplane.

3.Tighten the two captive screws on the front of the Power Input module firmly (refer to Figures 3-1 and 3-2).

4.Replace the wire channel cover.

5.Review “Restarting the ROC827” in Section 6, Troubleshooting.

6.Return power to the ROC827.

3.5Connecting the ROC827 to Wiring

The following paragraphs describe how to connect the ROC827 to power. Use the recommendations and procedures described in the following paragraphs to avoid damage to equipment.

Use 12 American Wire Gauge (AWG) wire or smaller for all power wiring.

Caution	Always turn off the power to the ROC827 before you attempt any type of
	wiring. Wiring of powered equipment could result in personal injury or
	property damage.

To avoid circuit damage when working with the unit, use appropriate electrostatic discharge precautions, such as wearing a grounded wrist strap.

To connect the wire to the removable block compression terminals:

1.Bare the end (¼ inch maximum) of the wire.

2.Insert the bared end into the clamp beneath the termination screw.

3.Tighten the screw.
