WARNING: When a hazardous area is present, ensure the union nut and blanking plug are

properly tted in the conduit opening. The explosion-proof rating applies only when the union

nut and blanking plug are secured in place. When the union is broken, the device is no longer

explosion-proof.

WARNING: Before disassembling the union nut and blanking plug, make sure the area is non-

hazardous.

Adapter Kit Installation

If the NuFlo USB adapter is purchased as a kit, install it in the Scanner 2000 according to the steps below.

The USB adapter is comprised of a USB adapter socket, a blanking plug, and a union nut. The blanking plug

and union nut are connected to the adapter only when the USB port is not in use.

1. Remove the plug from a conduit opening in the Scanner 2000 enclosure.

2. Thread the cable of the adapter through the conduit opening and screw the adapter into place.

3. Wire the adapter cable to either communications port on the Scanner 2000 main circuit board as shown in

the wiring diagram (black wire to negative terminal).

4. If the USB port will not be used immediately, nest the blanking plug inside the union nut and screw the

union nut onto the adapter to cover the USB socket. Hand-tighten to ensure a snug connection.
