NOTE: Be sure to connect correspondingly numbered "Data" and "Data & Power" ports. Ethernet Power Supply User s Guide 2-3 Appendix A — Safety Information Safety Information A Read the following safety information before performing any installation, removal, or maintenance procedure on the Ethernet Power Supply. WARNING Warnings contain directions that must be followed for personal and product safety. Follow all directions carefully. WARNING Read the installation instructions in Section 2 before connecting the Ethernet Power Supply to its power source. WARNING Follow basic electricity safety measures whenever connecting the Ethernet Power Supply to its power source. WARNING The Ethernet Power Supply chassis is intended to be grounded. Ensure the power host is connected to earth ground during normal use. Ethernet Power Supply User s Guide A-1 Appendix A — Safety Information WARNING This product relies on the building installation for short-circuit (overcurrent) protection. Make sure a fuse or circuit breaker no larger than 120VAC, 15A. U.S. (240VAC, 10A international) is used on the phase conductor. WARNING Do not work on the system or connect or disconnect cables during periods of lightning activity. WARNING A voltage mismatch can cause equipment damage and may pose a fire hazard. If the voltage indicated on the label is different from the power outlet voltage, do not connect the Ethernet Power Supply to this power outlet. WARNING For shelf-mounted equipment, make sure the surface is stable and strong enough to support the equipment. Do not stack more than four Ethernet Power Supply units on top of one another. WARNING Ultimate disposal of this product should be handled according to all national laws and regulations. WARNING The Ethernet Power Supply "Data" and "Data & Power" ports are shielded RJ-45 data sockets. They cannot be used as Plain Old Telephone Service (POTS) telephone sockets. Only RJ-45 data connectors may be connected to these sockets. A-2 Ethernet Power Supply User s Guide Appendix A — Safety Information § Installation and removal of the Ethernet Power Supply must be carried out by qualified personnel only. § Power Cord Set: The power cord must be approved for the country in which it is used: U.S.A. and Canada Denmark Switzerland § The cord set must be UL- approved and CSA certified. § The minimum specification for the flexible cord is: No. 18 AWG Type SV or SJ 3-conductor § The cord set must have a rated current capacity of at least 10A. § The attachment plug must be an earth-grounding type with a NEMA 5-15P (15A, 125V) or NEMA 6-15P (15A, 250V) configuration. § The supply plug must comply with section 107-2-D1, standard DK2-1a or DK2-5a. § The supply plug must comply with SEV/ASE 1011. Ethernet Power Supply User s Guide A-3 Appendix A — Safety Information § The appliance coupler (the connector to the unit and not the wall plug) must have a configuration for mating with an EN60320/IEC320 appliance inlet. § The socket outlet must be near to the unit and easily accessible. You can only remove power from the unit by disconnecting the power cord from the outlet. § This unit operates under SELV (Safety Extra Low Voltage) conditions according to IEC 950. The conditions are maintained only if the equipment to which it is connected also operates under SELV conditions. § Switzerland only: The supply plug must comply with SEV/ASE 1011. § France and Peru only: This unit cannot be powered from IT supplies. If your supplies are of IT type, this unit must be powered by 230V (2P+T) via an isolation transformer ratio 1:1, with the secondary connection point labeled Neutral, connected directly to earth (ground).
