Read the product documentation carefully before installing or operating the product. If you encounter the following marking during installation or operation, consult product documentation to find out the nature of the potential hazards and any actions which have to be taken to avoid them:

WARNING Only licensed experts may install electrical components. They must adhere to local and state legislation and regulations.
WARNING Make sure that you prepare and connect only de-energized wires.
WARNING Transmitters powered with AC (mains) power must be connected only to a grounded (earthed) power supply (class I equipment).
WARNING Only licensed experts may connect the AC (mains) power connection to the power supply. A readily accessible disconnect device must be incorporated in the fixed wiring.
WARNING Attach only cables with temperature rating of minimum +80 °C (+176 °F) to the PELV power supply terminal.

INDIGO520 PoE version transmitters shall be supplied by a Power Sourcing Equipment (PSE) unit which fulfils the requirements of IEEE802.3at specifications.


INDIGO510 and INDIGO520 PELV version transmitters shall be supplied by an isolated power source which fulfils the requirements of: Limited-Energy Circuit in accordance with UL/CSA 61010-1 or Limited Power Source (LPS) in accordance with (UL/CSA 60950-1 or EN 62368-1, Annex Q) or Class 2 supply source which complies with the National Electrical Code (NEC), NFPA 70, Clause 725.121 and Canadian Electrical Code (CEC), Part I, C22.1.

CAUTION Attach only Vaisala Indigo-compatible probes to the transmitter.
CAUTION Do not modify the unit or use it in ways not described in the documentation. Improper modification or use may lead to safety hazards, equipment damage, failure to perform according to specification, decreased equipment lifetime, or the warranty becoming void.
CAUTION The transmitter's Ethernet interface is designed to be used in trusted network environments (trusted corporate LAN or VPN-based connection over the Internet). Avoid connecting the transmitter directly to a public network because the device can be attacked by a malicious user through the network.
CAUTION A factory reset deletes all current settings of the device. After the factory reset, you need to reconfigure the settings, including outputs and relays. When you connect to the web interface the next time, you will be prompted to give the activation code and create new users.
CAUTION Do not replace detachable mains supply cords by inadequately rated cords.
CAUTION Do not use the transmitter in a manner not specified by Vaisala. If the transmitter is used in an unspecified manner, the protection provided by the equipment may be impaired.
