| WARNING Only licensed experts may install electrical components. They must adhere to local and state legislation and regulations. |
| WARNING Ground the product and verify outdoor installation grounding periodically. Failure to provide proper grounding can result in injury or death from electrical shock and can severely damage the equipment. |
| WARNING Do not operate in an explosive atmosphere, for example, when flammable gases or fumes are present. Operation of electrical equipment in such an environment constitutes a safety hazard. |
| WARNING Make sure that you prepare or connect only de-energized wires. |
| WARNING A long cable between units (sensors, transmitters, power supplies, and displays) can cause a lethal lightning-induced current surge. Always ground the enclosure to a suitable grounded location with a short, low-resistance cable. |
| CAUTION Do not damage or change the wiring. Incorrect wiring can cause damage and prevent or limit operation. |
| WARNING The system is powered from several power sources to ensure uninterrupted service. To make the system non-energized, disconnect all power sources. |
