SECTION 2.0

INSTALLATION

This section is for installation of the controller.

WARNING

All electrical installation must conform to the National Electrical Code, all state and local codes, and all plant codes and standards for electrical equipment. All electrical installations must be supervised by a qualified and respon- sible plant electrician.

2.1 LOCATING THE CONTROLLER

Position the Model 54e pH/ORP controller to minimize the effects of temperature extremes and to avoid vibration and shock. Locate the controller away from your chemical process to protect it from moisture and fumes.

Select an installation site that is more than 2 ft from high voltage conduit, has easy access for operating personnel, and is not exposed to direct sunlight.

2.2 UNPACKING AND INSPECTION

Inspect the exterior of the shipping container for any damage. Open the container and inspect the controller and related hardware for missing or damaged parts.

If there is evidence of damage, notify the carrier im- mediately. If parts are missing, contact Rosemount Analytical customer support.

2.3.2 Wall or Surface Mounting:

1.Mount the bracket to the controller using the sup- plied four screws as shown in Figure 2-2.

2.Mount controller mounting bracket to wall using any appropriate fastener such as screws, bolts, etc (see Figure 2-1 below).

2.3.3 Pipe Mounting:

2.3 MECHANICAL INSTALLATION

2.3.1 Mounting the Controller

The Model 54e pH/ORP controller may be supplied with a mounting bracket accessory. If you use the mounting bracket on wall or pipe installations, avoid mounting on pipes which vibrate or are close to the process. The bracket may be modified to mount the controller on I-beams or other rigid members. You can also fabricate your own bracket or panel mount the controller using the bracket as an example.

1.Attach the mounting bracket to the rear of the con- troller and tighten the four screws as shown in Figure 2-2.

2.Place supplied U bolts around the mounting pipe and through the pipe mounting bracket and mounting bracket. Tighten the U bolt nuts until the controller is securely mounted to the pipe.
