Connection to Sentinel Node
Sentinel Compatibility
The current available from the solar system is limited due to the IS certification so the solar system
may not be used for all Sentinel node configurations.
The following configurations are supported:
-Sentinel Digital
-Sentinel HART
-Sentinel Analog in 1-5V mode (with a sensor power draw of less than 8mA)
-Sentinel Modbus (with a sensor power draw of less than 10mA)
-Sentinel Turbine
-Sentinel Thermocouple
Note: The Sentinel Solar cannot be used with a Sentinel Analog operating in 4-20mA mode.

Wiring Requirements
To ensure intrinsic safety is maintained it is required that the installer follow these guidelines
when connecting sensors to the SignalFire node.
The sentinel node must be purchased for use with the solar system. The “solar ready” Sentinel
node has a cable gland for the power cable. This should be routed away from any sensor wires
entering the Sentinel node.
See pictures for proper wire routing examples.
-The solar power cable must enter through the cable gland
-All wiring should be neat and orderly

Mounting
The solar system comes on a mounting bracket which may be mounted to either a horizontal
or vertical pole using hoe clamps. The tabs on the bracket may be bent to fit around the pole.
Alternatively, U-bolts can be placed through the holes in the rear of the bracket for pole
mounting.
The system should be installed with the solar panel facing south with a good view of the sky.
Mount the system so that the mounting side of the triangle is vertical and the battery box is at the
bottom.
SignalFire also supplies a varity of mounting kits for various sensors. Contact SignalFire or visit
http://www.signal-fire.com/sentinel-bracket-kits/ for information.

Cleaning Instructions
The solar panel and bracket may be cleaned with water, mild soap, and a damp cloth as
needed. High pressure washing is not recommended.
