Warnings and Cautions 
Before installation 
Warning: Before installation, TURN OFF the external circuit breaker which supplies 
power to the device. 
Before connecting the device to the power supply, verify that the output voltage is 
within specifications of the power supply. (See “Technical specifications” on page 
37.) 
Do not apply power to the device until after the installation has been completed.  
The equipment can be damaged if this precaution is not observed. 
Fire Safety and Liability Notice 
Warning: Never connect card readers to any critical entry, exit door, barrier, elevator or 
gate without providing an alternative exit in accordance with all the fire and life 
safety codes pertinent to the installation. 
These fire and safety codes vary from city to city and you must get approval from 
local fire officials whenever using an electronic product to control a door or other 
barrier. Use of egress buttons, for example, may be illegal in some cities. In most 
applications, single action exit without prior knowledge of what to do is a life safety 
requirement. Always make certain that any required approvals are obtained in writing.  
DO NOT ACCEPT VERBAL APPROVALS SINCE THEY ARE NOT VALID. 
Damage during shipment 
Caution: IF ANY DAMAGE TO THE SHIPMENT IS NOTICED, A CLAIM MUST 
BE FILED WITH THE COMMERCIAL CARRIER RESPONSIBLE FOR THE 
DAMAGE. 
Electrostatic discharge 
Caution: Electrostatic discharge (ESD) can damage integrated circuits and modules. To 
prevent damage always follow these procedures: 
Use static shield packaging and containers to transport all electronic components, 
including completed reader assemblies. 
Handle all ESD sensitive components at an approved static controlled workstation. 
These workstations consist of a desk mat, floor mat and an ESD wrist strap. 
Workstations are available from various vendors.
