2 Installation
2.1 General installation information
WARNING
Electrical shock
Installation and servicing of this product may expose personnel to
dangerous voltages.
Electrical installation must be in accordance with the National Electrical
Code (ANSI/National Fire Protection Agency-70) and/or any other
national or local codes.
The equipment is protected throughout by double insulation.

servicing.
Ensure that all equipment doors are closed and protective covers are in
place, except when maintenance is being performed by qualified
personnel.
Signal wiring must be rated at least 240 V.
Non-metallic cable strain reliefs do not provide grounding between
conduit connections. Use grounding type bushings and jumper wires.
Make sure that the instrument is connected and properly grounded
through a three-wire power source.
Proper use and configuration is the operator's responsibility.
1. Install the transmitter with a sun shield or out of direct sunlight and
areas with extreme temperatures.
2. Install the system in an area where vibrations and electromagnetic
and radio frequency interference are minimized or absent.
3. Keep the transmitter and sensor wiring at least 1 ft (0.30 m) from
high voltage conductors. Be sure there is easy access to the
transmitter and sample conditioning system.
4. The transmitter is suitable for panel, pipe, or surface mounting.

3 Wiring
3.1 General wiring information
The transmitter includes removable connectors and slide-out signal input
boards.The front panel is hinged at the bottom. The panel swings down for
easy access to the wiring locations.
3.1.1 Removable connectors and signal input boards
The transmitter uses removable signal input boards and communication
boards to facilitate wiring and installation.
You can remove each of the signal boards either partially or completely from
the enclosure for wiring. The transmitter has three slots for placement of up
to two signal input boards and one communication board.
Slot 1 - left Slot 2 - center Slot 3 - right
Communication board Input board 1 Input board 2
3.1.2 Wire the signal input boards
Slots 2 and 3 are for signal input measurement boards.
Procedure
1. Wire the sensor leads to the measurement board following the lead
locations marked on the board.
2. Carefully slide the wired board fully into the enclosure slot and take
up the excess sensor cable through the cable gland.
3. Tighten the cable gland nut to secure the cable and ensure a sealed
enclosure.
3.1.3 Digital communication boards
HART® and Profibus® DP communication boards will be available in the
future as options for Rosemount 1056 digital communication with a host.
The HART board supports Bell 202 digital communication over an analog
4-20 mA current output. Profibus DP is an open communication protocol
that operates over a dedicated digital line to the host.
3.1.4 Alarm relays
Emerson supplies four alarm relays with the switching power supply (85 to
264 Vac, 03 order code) and the 24 Vdc power supply (20 - 30 Vdc, 02 order
code). You can use all relays for process measurement(s) or temperature.
You can also configure any relay as a fault alarm instead of a process alarm.
Quick Start Guide 13
Quick Start Guide February 2022
In addition, you may configure any relay independently and program it to
activate pumps or control valves.
All process alarms, alarm logic (high or low activation or USP*), and
deadband are user-programmable. Customer-defined failsafe operation is
supported as a programmable menu function to allow all relays to be
energized or not energized as a default condition upon powering the
transmitter. You may program the USP* alarm to activate when the
conductivity is within a user-selectable percentage of the limit. USP*
alarming is available only when a contacting conductivity measurement
board is installed.
3.2 Preparing conduit openings
There are six conduit openings in all configurations of the transmitter.
Note
Emerson fits four of the openings with plugs upon shipment.

NOTICE
Always use proper cable gland fittings and plugs for wire and cable
installations.
Conduit openings accept 0.5 in (13 mm) conduit fittings or PG13.5 cable
glands. To keep the case watertight, block unused openings with Type 4X or
IP66 conduit plugs.
