Installation, Unpack, Mounting | Emerson M21, M22 specification

SECTION 1: Installation

1.1 Unpack

Carefully remove all components from the packaging and check them against the enclosed packing list. Inspect all components for obvious damage such as broken or loose parts. If you find any components missing or damaged, notify the representative or Net Safety Monitoring, immediately.

1.2 Mounting

Ensure transmitter and sensor are securely mounted, taking into consideration all requirements. Sensors may be installed directly to transmitters or remotely using a Certified Net Safety junction box. See Figure 11 when mounting sensor remotely.

1.2.1 Transmitter Orientation Option

Depending on the installation and mounting requirements, the transmitter enclosure (housing) may be mounted in different orientations as seen in Figure 2. To accommodate the different mounting orientations, the electronics module can be rotated inside the transmitter enclosure. See Section ‘1.2.3 Rotating electronics module relative to enclosure and conduit entries’ and Figure 4.

NOTE: Ensure the orientation allows proper wiring and adequate wire length inside the transmitter enclosure.
