Chapter 3: Installation & Startup

Overview

This chapter describes procedures to mount the M2 Transmitter in the monitoring

environment and wire it to input power and devices.

Mounting the M2 Transmitter

1. Select a mounting site that is representative of the monitoring environment. Consider

the following when you select the mounting site.

• Select a site where the M2 is not likely to be bumped or disturbed. Make sure

there is sufficient room to perform start-up, maintenance, and calibration

procedures.

• Select a site where the target gas is likely to be found first. For lighter gases,

mount the detector near the ceiling; for heavier gases, mount the detector near the

floor.

2. At the monitoring site, use #10 screws through the junction box’s two mounting holes

to secure the junction box to a vertical surface. Figure 11 - Figure 17 show the outline

and mounting dimensions for each version of the M2. Mount the M2 with the detector

facing down as shown in the following figures.
