Addendum – USB Barcode
Overview
Controllers have been equipped with an external USB port for barcode scanning. It is important to
note the following before using the port or the USB barcode reader.
1)
The barcode reader is not approved for Class I Division 2 locations (US) or a Group II
Category 3 Zone 2 (Europe) area, but can be used in a flammable area if the area is known to
be non-hazardous. It is up to the customer to determine how they determine if the area is non-
hazardous (through gas monitoring, detection, etc).
2)
The barcode reader or any other USB device is not intended to be permanently connected to the
external USB port. The external USB port is intended for intermittent use and USB devices
connected to it should be used for as short a time as possible.
3)
If a customer desires to keep a device permanently connected to the external USB port, the
customer must ensure that the USB device has the appropriate certifications for permanent use
in a Class I Division 2 location or a Group II Category 3 Zone 2 area.
USB Connection Port
A controller may be equipped with an external USB port. The external USB port allows a USB
connection to be made without having to open the controller door. Electrical devices should never be
operated, connected to, or disconnected from the USB port unless the area surrounding the equipment
is known to be free of flammable material. All controllers with a USB port on the controller will also
have a warning label (Figure A) for operation in a flammable area. The USB port has a cap that can be
used to cover the port when not in use.
