observed
This symbol, if noted on the instrument, references the instruction manual for operation and/or
safety information.
This symbol, when noted on a product enclosure or barrier, indicates that a risk of electrical shock and/or electrocution exists.
This symbol, if noted on the product, indicates the need for protective eye wear.
This symbol, when noted on the product, identifies the location of the conne ct ion for Protectiv e Earth (ground).
This symbol, when noted on the product, identifies the location of a fuse or current limiting device.

2.2 General Product Information

The controller enclosure is NEMA4X/IP66-rated and has a corrosion-resistant finish designed to withstand corrosive environmental constituents such as salt spray and hydrogen sulfide. The controller display shows the current reading plus a secondary measurement such as temperature if connected to a single sensor, or two readings with their corresponding secon dary measurement reading s when two sensors are connected.
Installation instructions for the contro ller are presen ted in th is manu al. If a system with a sensor and a controller has been purchased, complete information for installation and operation is also presented in the sensor system manual.
