Anleitung Zusammenfassung


Use the following procedure for connecting the output power wires for new equipment to a previously installed panel: Warning: The circuit breaker panel uses electrical voltage and current levels that may be considered an energy hazard. Only qualified personnel should be allowed to install, operate, maintain, or otherwise come into contact with this equipment when energized. Only insulated tools should be used on energized elements of the panel. 1. Remove the large protective cover from the rear side of the panel. 2. Turn off the circuit breaker for the circuit to which equipment will be added. 3. Connect the output power wiring to the power output terminals. Wire leads should be equipped with crimp-on spade lugs or ring connectors that have a minimum width of 0.32 inches (81.3 mm). The terminals also accommodate copper wire without lugs (insulation stripped back). The terminals can accept a variety of wire sizes up to #12 AWG with crimp-on spade lug or ring connectors or wires in sizes from #12 AWG to #22 AWG with insulation stripped back. In selecting wire size, follow local code referring to the ampacity guidelines provided in Appendix A. Caution: Use care to avoid shorting out adjacent terminals when connecting new output power wiring to a powered circuit breaker panel. Shorting can cause injury and damage the panel or the connected equipment. 4. Re-install the protective cover over the output power terminal blocks. 5. Switch the circuit breaker to the on position and verify that the breaker alarm indicator turns off. Page 25 © 2006, ADC Telecommunications, Inc. ADCP-80-570 • Issue 2 • March 2006 6.2 Using the Reset Switch The purpose of the Reset switch is to allow you to clear an alarm when you turn off a circuit breaker. When you press the Reset switch, any alarms currently existing are cleared but any new alarm will be reported. Use the following procedure: 1. If for some reason you need to turn off power to a particular circuit, switch the circuit breaker to an off position and then immediately press the Reset Switch. 2. When ready, turn the circuit back on. Note: Switching the circuit breaker back on returns the circuit to the normal alarm reporting mode. If any other circuit has an active alarm that was cleared by the Reset switch, that alarm will continue to be cleared until the circuit breaker for that circuit is turned back on. 7 MAINTENANCE Maintenance includes performing a routine inspection and replacing a circuit breaker. 7.1 Performing a Routine Inspection Caution: Take care to avoid damaging the circuit breakers or wiring. 1. Inspect the panel for damage to the circuit breakers and for damaged or broken wires at the power and external alarm connections. 2. If excessive dirt is found during the inspection, brush or wipe dust and dirt from the panel with a soft bristle brush or soft cloth. 3. If any circuit breaker is broken or damaged, replace the circuit breaker. 7.2 Replacing a Circuit Breaker Any existing circuit breaker may be field-replaced with an identical circuit breaker or with a breaker that has the same rating. Use the following procedure to replace an existing circuit breaker with a new breaker: 1. Turn-off or disconnect the power from the power bus (either A or B) that supplies current to the circuit breaker to be replaced. 2. Press the Reset switch to suppress alarms for the “off” circuits. Danger: During normal operation, the terminal connections on the circuit breakers are electrically energized. Failure to disconnect the power from the power bus that supplies current to the circuit breaker being replaced may cause severe personal injury to the installer and/or equipment damage.

Insert a flat-bladed screwdriver into the slot above the circuit breaker as shown in Figure 19. 4. Push down and forward on the upper circuit breaker lock tab until the top of the circuit breaker is released from the panel. 5. Hold the top edge of the circuit breaker to keep the circuit breaker from snapping back into the panel when the screwdriver is withdrawn from the slot. 6. Insert a flat-bladed screwdriver into the slot below the circuit breaker. 7. Push down and forward on the lower circuit breaker lock tab until the bottom of the circuit breaker is released from the panel. 8. Pull the circuit breaker forward and out of the panel to expose the wiring connections on the rear side of the circuit breaker. Figure 19. Releasing the Circuit Breaker Lock Tab 20646-A 1. INSERT SCREWDRIVER INTO SLOT AND DEPRESS TO RELEASE LOCKING TAB. 2. TILT FUSE FORWARD. ADCP-80-570 • Issue 2 • March 2006 9. Disconnect the power and load wires (#14 AWG white and black wires) and the alarm wires (#24 AWG black wires) from the terminals on the rear side of the circuit breaker as shown in. 10. Connect the power and load wires to the specified terminals on the rear side of the replacement circui...
