Installation kit The Model 3350/3700 installation kit includes the parts shown in Figure 1. Figure 1. Field-mount installation kit 4 x Flat washer 4 x Lock washer 4 x M8x16 Bolt assemblies Mounting bracket Transmitter can be oriented on bracket. See Step 3. 2 STEP 1. Choosing a location Choose a location for the transmitter based on the requirements described below. WARNING Improper installation in a hazardous area could cause an explosion. Install the transmitter in an area that is compatible with the rating on the approvals tag. See Figure 3. Environmental requirements Install the Model 3350/3700 according to specified limits: • Ambient temperature: –4 to +140 °F (–20 to +60 °C) Dimensions See Figures 2, 3, and 4 for Model 3350/3700 dimensions. Visibility of tags To ensure personal and system safety, all tags attached to the housing must remain visible. Clean them as often as necessary. Replace tags that are damaged, missing, or worn. See Figure 3 for location of approvals tag. 3 Figure 2.
