electrical shock ? energy hazards ? fire ? mechanical and heat hazards ? radiation hazards ? chemical hazards on-board dc/dc converters and dc/dc regulators are defined as component power supplies. as components they cannot fully comply with the provisions of any safety requirements without ?conditions of acceptability?. clearance between conductors and between conductive parts of the component power supply and conductors on the board in the final product must meet the applicable safety requirements. certain conditions of acceptability apply for component power supplies with limited stand-off (see mechanical information and safety certificate for further information). it is the responsibility of the installer to ensure that the final product housing these components complies with the requirements of all applicable safety standards and regulations for the final product. component power supplies for general use should comply with the requirements in iec/en/ul 60950-1 safety of information technology equipment. product related standards, e.g. ieee 802.3af power over ethernet , and ets-300132-2 power interface at t he input to telecom equipment, operated by direct current (dc) are based on iec/en/ul 60950-1 with regards to safety. ericsson power modules dc/dc converters, power interface modules and dc/dc regulators are ul 60950-1 recognized and certified in accordance with en 60950-1. the flammability rating for all construction parts of the products meet requirements for v-0 class material according to iec 60695-11-10, fire hazard testing, test flames ? 50 w horizontal and vertical flame test methods. isolated dc/dc converters & power interface modules the product may provide basic or functional insulation between input and output according to iec/en/ul 60950-1 (see safety certificate), differ ent conditions shall be met if the output of a basic or a func tional insulated product shall be considered as safety extra low voltage (selv). for basic insulated products (see safety certificate) the output is considered as safety extra low voltage (selv) if one of the following conditions is met: ? the input source provides supplementary or double or reinforced insulation from the ac mains according to iec/en/ul 60950-1. ? the input source provides functional or basic insulation from the ac mains and the product?s output is reliably connected to protective earth according to iec/en/ul 60950-1. for functional insulated product s (see safety certificate) the output is considered as safety extra low voltage (selv) if one of the following conditions is met: ? the input source provides double or reinforced insulation from the ac mains according to iec/en/ul 60950-1. ? the input source provides basic or supplementary insulation from the ac mains and the product?s output is reliably connected to protective earth according to iec/en/ul 60950-1. ? the input source is reliably connected to protective earth and provides basic or supplementary insulation according to iec/en/ul 60950-1 and the maximum input source voltage is 60 vdc. galvanic isolation between input and output is verified in an electric strength test and the isolation voltage (v iso ) meets the voltage strength requir ement for basic insulation according to iec/en/ul 60950-1. it is recommended to use a slow blow fuse at the input of each dc/dc converter. if an input filter is used in the circuit the fuse should be placed in front of the input filter. in the rare event of a component problem that imposes a short circuit on the input source, this fuse will provide the following functions: ? isolate the fault from the input power source so as not to affect the operation of other parts of the system ? protect the distribution wi ring from excessive current and power loss thus preventing hazardous overheating non - isolated dc/dc regulators the dc/dc regulator output is selv if the input source meets the requirements for selv circuits according to iec/en/ul 60950-1. e pkb4000c series direct converters input 36-75 v, output up to 60 a / 144 w en/lzt 146 377 r4d september 2013 ?
