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 44.)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. 

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. 

IF ANY DAMAGE TO THE SHIPMENT IS NOTICED, A 

CLAIM MUST BE FILED WITH THE COMMERCIAL CARRIER 
RESPONSIBLE FOR THE DAMAGE. 

Electrostatic discharge (ESD) can damage integrated circuits and 

modules.
