Preparing the ISS and Radiation Shield The radiation shield must be partially disassembled in order to make necessary cable connections, and to install batteries in the solar-powered wireless ISS. The ISS sensors are connected by cables to the Sensor Interface Module (SIM), located inside the radiation shield. The SIM contains electronics that measure and store weather values for transmission to the console via cable or radio waves.

Powering the Fan The Cabled Vantage Pro is powered by an AC-power adapter. The Wireless Vantage Pro ISS is solar-powered with batteries for overnight power. Refer to the Junction Board Connections illustration when powering the fans.
PAGE 8
Wireless Vantage Pro The solar-powered fan on the Wireless ISS will begin operating as soon as you install the batteries. To prevent discharging the batteries, you should only power the fan in a Wireless Vantage Pro immediately before mounting the ISS in its final location. 1. On the Radiation Shield fan plate, insert the O-ring in the groove around the edge of each battery compartment. 2.

Mounting the ISS Refer to this section in your ISS Installation Manual. Additional Mounting Options Refer to this section in your ISS Installation Manual. Fan-Aspirated ISS Options Batteries The Wireless Fan-Aspirated ISS is solar powered and is supplied with two NiCad C-cell batteries. At your option you may decide to install either zero, one, or two C-cell batteries. ✦ Install two fan batteries for maximum length of overnight aspiration but with slightly lower average daytime aspiration.
