3. LABEL
The reader’s front label can provide identification and instructions. The front label is usually a customer designed
and supplied part. Should the customer not wish to provide a label, a weather-resistant Cubic label is available.
4. WEATHERPROOFING
The reader, as supplied, is intended for use inside buildings. It is not weatherproof. It can be used on the outside
of buildings if it is mounted on a nonporous surface using an available gasket and front label. If used, the gasket
should be attached to the back of the reader and the label should be attached to the front of the reader. Peel the
protective paper from the adhesive backing on the label and on the gasket and attach them to the unit.
5. WIRE
The wire used to supply power to the unit (via pins 7 and 8 of the terminal block) should consist of a twisted pair
of sufficient size to carry a maximum of 0.3A dc.
The allowable voltage drop in the wires depends upon whether the unit’s optical isolator is being used (pin 2 is
not connected to pin 8 and pin 6 is not connected to pin 7) or is being bypassed (pin 2 is connected to pin 8 and
pin 6 is connect to pin 7).
If the optical isolator is being used, then the voltage drop should be low enough to assure that the unit receives at
least 8 volts and at least 0.3A.
If the optical isolator is not being used, then the voltage drop should be no more than 0.25 Vdc per wire (of the
twisted pair of wires) or there will be too much ground offset between the unit and the controller to which it is
attached.
