CAUTION: To reduce the risk of electric shock or energy hazards: 
•  This equipment must be installed by trained service personnel, as defined by the NEC and IEC 
60950-1, Second Edition, the standard for Safety of Information Technology Equipment. 
•  Connect the equipment to a reliably grounded SELV source. An SELV source is a secondary 
circuit that is designed so normal and single fault conditions do not cause the voltages to 
exceed a safe level (60 V DC). 
•  The branch circuit overcurrent protection must be rated 24 A.
