Page 9: Electrical Safety
1�4 Electrical Safety WARNING! The DC input to the modules (and the converter system) – though not dangerous in volt- age – has a high short circuit current capacity that may cause severe burns and electri- cal arcing. The DC output is a potentially dangerous voltage. Do not touch the output connections when under power. -
Page 10: Product Overview
2� Product Overview 2�1 Introduction The 100VA eLimiter+ is a unique remote powering solution that meets the NEC requirements for remote power- ing of electrical devices such as iDAS (indoor distributed antenna systems), remote radios, security cameras, different sensors, access controllers and alarms. The unit can be used to distribute -48Vdc to remote equipment without the use of conduits and complies with the NEC requirement for Class 2 power limited circuits. -

6�4�2 Thermal Management with Fan Tray If operating more than 1 continuous shelf a fan tray is required. One fan tray can be used for up to three shelves. Three contiguous shelves require a fan tray and two baffles to meet the specified cooling requirements. Install the fan tray directly below the three converter shelves and a baffle tray below the fan tray. -
Page 21: Figure 7 - Thermal Management Without A Fan Tray
6�4�3 Thermal Management without Fan Tray When installing the eLimiter+ without a fan tray, 3RU space is required for thermal management. Each shelf requires a 1RU air space, 1 baffle tray and then an additional 1RU air space, see Figure 7. Install the first converter shelf and then leave 1 RU of air space directly above the converter shelf. -
Page 22: Input And Output Wiring
6�5 Input and Output Wiring This power system is suitable for installation as part of a Common Bonding Network (CBN) and is intended to be used in a DC-I configuration (isolated from frame ground). This system is intended to be used with a -48Vdc rectifier/ battery system at the input, and surge protectors and line terminators at the output. -
