3.4 Installing 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.
3.5 Connecting 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.
