An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that
no exposed portion of the DC-input power source wire extends from the connector(s) or terminal block(s).
Statement 122
Warning
7.
Use a ratcheting torque flathead screwdriver to torque the power connector captive screws (above the
installed wire leads) to 5in-lb (0.565 Nm).
Do not over-torque the power connector’s captive screws. The torque should not exceed 5in-lb (0.565 Nm).
Caution
8.
Connect the other end of the positive wire to the positive terminal on the DC power source, and connect
the other end of the return wire to the return terminal on the DC power source.
When you are testing the switch, one power connection is sufficient. If you are installing the switch and
are using a second power source, repeat Step 4 through Step 8 using the second power connector.
Attaching the Power Connectors to the Switch
To attach the power connectors to the front panel of the switch, follow these steps:
1.
Insert one power connector into the DC-A receptacle on the switch front panel, and the other into the
DC-B receptacle.
Failure to securely tighten the captive screws can result in an electrical arc if the connector is accidentally
removed. Statement 397
Warning
Use twisted-pair supply wires suitable for 86°F (30°C) above surrounding ambient temperature outside the
enclosure. Statement 1067
Warning
Installation of the equipment must comply with local and national electrical codes. Statement 1074
Warning
2.
Use a ratcheting torque flathead screwdriver to tighten the captive screws on the sides of the power
connectors.
When you are testing the switch, one power source is sufficient. If you are installing the switch and are
using a second power source, repeat this procedure for the second power connector (DC-B), which installs
just below the primary power connector (DC-A).
When you are installing the switch, secure the wires coming from the power connector so that they cannot
be disturbed by casual contact. For example, use tie wraps to secure the wires to the rack.
Applying Power to the Power Converter
Move the circuit breaker for the AC outlet or the DC control circuit to the
on
position.
