Connecting The Equipment
•
Route the necessary cabling, and connect the OPX-X to the digital communications system per the connections
detailed on the next page.
•
The installation requires a grounding wire separate from the third-wire AC line cord ground. The OPX-X
cabinet provides a ground stud. Connect a #10 or #12, insulated, solid copper, wire between this ground stud
and either the ground stud on the digital communications system cabinet or a reliable earth ground.
•
Plug the AC line cord for the OPX-X into a 117 VAC outlet. Observe the status light on the unit, and insure
that it turns on steady.
CAUTION
To help insure that foreign voltages, which could appear on the TELCO lines, do not damage the system,
be sure gas discharge tubes or similar protection devices are installed, and properly grounded, in all
connected TELCO lines.
2.4
Verifying Proper Installation
Use a voltmeter to check for the presence of either AC or DC voltage on the OPX1 and OPX 2 ports.
Make these voltage measurements with all system wiring installed and the AC power turned off.
1. Measure for both AC and DC voltage between the TIP lead of the OPX 1 port and the KSU grounding stud.
The measured voltage must be 0 volts.
2. Measure for both AC and DC voltage between the RING lead of the OPX 1 port and the KSU grounding stud.
The measured voltage must be 0 volts.
3. Repeat steps 1 and 2 for the OPX 2 port.
4. Apply AC power to the OPX-X.
5. Repeat steps 1–3. The measured voltage must now be approximately -50VDC.
