To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a time-delay fuse with a maximum rating of 6 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used.

Page 7 BATTERY Data Sheet GE EQW006 Series, Eight Brick Power Modules: DC-DC Converter 36 – 75Vdc Input; 12Vdc Output; 6A Output Current Safety Considerations For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL60950, CSA C22.2 No. 60950-00 and VDE 0805:2001- rd 12 (IEC60950, 3 Ed). These converters have been evaluated to the spacing requirements for Basic Insulation, per the above safety standards; and 1500 Vdc is applied from Vi to Vo to 100% of outgoing production. For all input voltages, other than DC MAINS, where the input voltage is less than 60V dc, if the input meets all of the requirements for SELV, then:  The output may be considered SELV. Output voltages will remain within SELV limits even with internally-generated non-SELV voltages. Single component failure and fault tests were performed in the power converters.  One pole of the input and one pole of the output are to be grounded, or both circuits are to be kept floating, to maintain the output voltage to ground voltage within ELV or SELV limits. For all input sources, other than DC MAINS, where the input voltage is between 60 and 75V dc (Classified as TNV-2 in Europe), the following must be adhered to, if the converter’s output is to be evaluated for SELV:  The input source is to be provided with reinforced insulation from any hazardous voltage, including the AC mains.  One Vi pin and one Vo pin are to be reliably earthed, or both the input and output pins are to be kept floating.  Another SELV reliability test is conducted on the whole system, as required by the safety agencies, on the combination of supply source and the subject module to verify that under a single fault, hazardous voltages do not appear at the module’s output. The power module has ELV (extra-low voltage) outputs when all inputs are ELV. All flammable materials used in the manufacturing of these modules are rated 94V-0, and UL60950 A.2 for reduced thickness. The input to these units is to be provided with a maximum 6A time- delay in the unearthed lead. October 1, 2015 ©2012 General Electric Company. All rights reserved.
