WARNINGS

RISK OF ELECTRICAL SHOCK

Making cable connections to and servicing this instru­ment require access to shock hazard level voltages
which can cause death or serious injury, therefore,
disconnect all hazardous voltage before accessing
the electronics.

Relay contacts made to separate power sources
must be disconnected before servicing.

Electrical installation must be in accordance with the
National Electrical Code (ANSI/NFPA-70) and/or
any other applicable national or local codes.

Unused cable conduit entries must be securely
sealed by non-flammable closures to provide enclo­sure integrity in compliance with personal safety and
environmental protection requirements. Use NEMA
4X or IP65 conduit plugs supplied with the instrument
to maintain the ingress protection rating (IP65).

For safety and proper performance this instrument
must be connected to a properly grounded three­wire power source.

Proper relay use and configuration is the responsi­bility of the user. No external connection to the
instrument of more than 60VDC or 43V peak
allowed with the exception of power and relay termi­nals. Any violation will impair the safety protection
provided.

Do not operate this instrument without front cover
secured. Refer installation, operation and servicing
to qualified personnel.

WARNING

This product is not intended for use in the res­idential, commercial or light industrial environ­ment per certification to EN50081-2.

SENSOR CHOICE GUIDELINES

The Model 54eC is compatible with both contacting and inductive conductivity sensors. The best sensor for an application
depends on many factors, among them are the conductivity to be measured, the compatibility of the sensor's wetted mate­rials with the process chemicals and conditions, and the mounting arrangement. The tables below are provided as an aid
for choosing an appropriate sensor.

MODEL 54e C INSTALLATION

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
responsible plant electrician.

LOCATING THE CONTROLLER

Position the Model 54e C 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.

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 immediately. If
parts are missing, contact Rosemount Analytical customer sup­port.

MECHANICAL INSTALLATION

Mounting the Controller

The Model 54e C 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.

Wall or Surface Mounting:

1. Mount the bracket to the controller using the supplied four
screws.

2. Mount controller mounting bracket to wall using any appro­priate fastener such as screws, bolts, etc

Pipe Mounting:

1. Attach the mounting bracket to the rear of the controller and
tighten the four screws.

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.

Panel Mounting:

The controller is designed to fit into a 5.7 x 5.7 inch (DIN standard
144x144 mm) panel cutout (Figure 2-3). Installation requires both
front and rear access.

1. Install the controller as shown in Figure 2-3. Insert the instru­ment enclosure through the front of the panel cutout and align
the panel mounting brackets as shown.

2. Insert two mounting bracket screws through each of the two
mounting brackets and into the tapped holes in the rear of the
controller enclosure and tighten each screw.

3. Insert four panel mounting screws through each hole in the
mounting brackets. Tighten each screw until the mounting
bracket holds controller firmly in place. To avoid damaging
the controller mounting brackets, do not use excessive force.
