E2-455 User Manual ATTENTION! Incorrect termination of the supply wires may cause internal damage. Before turning the power on double-check ALL connections by referring to this User Manual. CAUTION To comply with FCC RF Exposure requirements in section 1.1310 of the FCC Rules, antennas used with this device must be installed to provide a separation distance from all persons as described in section “Safety Notices” below to satisfy RF exposure compliance.
E2-455 User Manual FCC (USA) Exposure to RF energy is an important safety consideration. The FCC has adopted a safety standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated equipment as a result of its actions in Docket 93-62 and OET Publication KDB 447498 D01. Depending on antenna type, ensure the following minimum separation distances from antennas for (A) Occupational and (B) General Population.

E2-455 User Manual 1 Introduction The E2-455 is a radio modem module used as a base radio for a number of Elpro wireless products, with additional products to be added in the future. It operates as a wireless network adapter for transfer of 802.11 format data frames over lower speed wireless links. The E2-455 consists of a host microcontroller, an RF transceiver section, and a power supply section.
E2-455 User Manual 2.1 Mounting Points Four mounting points are provided for 2.5mm Mounting screws. 2.2 Heat-Sink Block A Heat-Sink should be connected to the device’s Heat-Sink block to prevent the power amplifier overheating. The interface to the Heat-Sink block uses two M3 screws separated by 15mm, with engagement depth between 3mm-4mm. Use heat-paste or other heat-conducting material to provide an effective heat conduction path from the heat-sink block to the supplied heat-sink. 2.
