CAUTION!

USE WIRE SUITABLE

FOR 75° MINIMUM

NOTES:

• For supply connections use 16 AWG or larger wires rated for at least 75° C

• Use copper conductors only

• Class 2 wiring must be separated a minimum of 1/4 inch from any class 1 conductor

IMPORTANT!

Terminal identification of the panel mount controller is different from terminal identification of the wall/rail mount controller! This manual contains wiring instructions for both types of controllers.

Be sure to follow the instructions that pertain to the controller you are using.

Mounting Requirements

Panel Mount Controller

Select a mounting location with the following characteristics:

1) Minimal vibration.

2) An ambient temperature range between 0 and 50°C (32 and 122 °F).

3) Easy access to the rear of the instrument.

4) No corrosive gases (sulfuric gas, ammonia, etc.).

5) No water or other fluid (i.e. condensation).

6) Relative humidity of 20% to 80% non condensing.

Bracke t

Gasket

The instrument can be mounted on a panel up to 15 mm (0.591 in) thick with a square cutout of 45 x 45 mm (1.772 x 1.772 in). For outline refer to Dimensions and Panel Cutout.

Panel surface texture must be better than 248 microinches.

The instrument is shipped with a rubber panel gasket (50 to 60 Sh). To assure the IP65 and NEMA 4 protection, insert the panel gasket between the instrument and the panel as shown below.

Install the instrument as follows:

1) Insert the instrument in the gasket.

2) Insert the instrument in the panel cutout.

3) Pushing the instrument against the panel, insert the mounting bracket.

4) Torque the mounting bracket screws between

0.3 and 0.4 Nm (2.66 and 3.54 lbf-in).

5) To insure NEMA 4X/IP65 protection, make sure the instrument does not move within the cutout .

WARNING:

1) The correct functionality of these instruments is guaranteed only if transport, storage, installation, wiring, working condition and maintenance are executed in compliance with this manual.

2) The protection degree of these instruments is equal to IP 20 (according to IEC529) and they are connected to dangerous power lines, for these reasons:

-installation, wiring and maintenance must

be executed by qualified personnel;

-all warnings contained in this manual must be complied.

3) The safety requirements for Permanently Connected Equipment say:

-a switch or circuit-breaker shall be

included in the building installation;

-It shall be in close proximity to the

equipment and easy to reach for the operator;

-it shall be marked as the disconnecting device for the equipment. NOTE: a single switch or circuit-breaker can drive more than one instrument.

4) Before to executing any operation on the connections, disconnect the instrument from the power line by the circuit breaker.

GENERAL ASSEMBLING INFORMATION

Select a cleaned location, easy to reach, where minimum vibrations are present and the ambient temperature is within 0 and 50 °C (32 and 122 °F). These instruments can be mounted either on wall or DIN rail.

RAIL MOUNTING

Use DIN rail in accordance with EN 50 022 (35 x 7.5 mm or 35 x 15 mm).

WALL MOUNTING

For wall mounting, use the (A) holes. In this case it is advisable to use four M4 screws with a torque of 1Nm.

Wiring Guidelines

Panel Mount Controllers

A) Measuring Inputs

NOTE: Any external components (like Zener diodes, etc.) connected between sensor and input terminals may cause errors in measurement due to excessive and/or not balanced line resistance or possible leakage currents.

RTD INPUT -- Panel Mount Controller

RTD

TC Input

Shield

Thermocouple Input Wiring

NOTE:

1) Do not run input wires with power cables.

2) For TC wiring use proper compensating cable,

preferably shielded (see Appendix B).

3) Shielded cable should be grounded at one end

only.

NOTE:

1) Don’t run input wires with power cables.

2) Pay attention to the line resistance; a high line resistance may cause measurement errors.

3) When shielded cable is used, it should be grounded at one side only to avoid ground loop currents.

4) Resistance of the 3 wires must be the same.

mA, mV and V Inputs Wiring

NOTE:

1) Don’t run input wires together with power cables.

2) Pay attention to the line resistance; a high line resistance may cause measurement errors.

3) When shielded cable is used, it should be grounded at one side only to avoid ground loop currents.

4) The input impedance is equal to: Less than 5 Ω for 20 mAdc input Greater than 1 MΩ for 60 mVdc input Greater than 400 KΩ for 5 Vdc and 10 Vdc input

B) Logic Input - Panel Mount Controller

This input is used for remote acknowledgement (reset).

Safety note:

- Do not run logic input wiring with AC power cables.

Logic input

- Use an external dry contact capable of switching 0.5 mA, 5 Vdc.

- The instrument needs 100 ms to recognize a contact status variation.

- The logic inputs are NOT isolated from the measuring input.

C.1) Relay Outputs Panel Mount Controller

Class 1

(Alarm)

The OUT 1 contact rating is 3A/250V AC on resistive load. The OUT 2 contact rating is 2A/250V AC on resistive load. The number of operations is 1 x 10 rating. NOTES 1) To avoid electric shock, connect power

line at the end of the wiring procedure.

2) For power connections use No 16 AWG or larger wires rated for at last 75 °C.

3) Use cupper conductors only.

4) Don’t run input wires with power cables.

All relay contacts are protected by varistor against inductive load with inductive component up to 0.5 A.

NO - OUT 1

C - OUT 1

NC - OUT 1

at specified

The following recommendations avoid serious problems which may occur, when relay outputs are used with inductive loads.

C.2) Inductive Loads

High voltage transients may occur switching inductive loads. Through the internal contacts these transients may introduce disturbances which can affect the performance of the instrument. For all the outputs, the internal protection (varistor) assures a correct protection up to 0.5 A of inductive component.

The same problem may occurs when a switch is used in series with the internal contacts as shown below:

LOAD

External Switch in Series with Internal Contact

In this case it is recommended to install an additional RC network across the external contact as shown above. The value of capacitor (C) and resistor (R) are shown in the following table.

devices with one remote master unit.

7) Safety requirements for permanently connected equipment:

- Include a switch or circuit-breaker in the installation.

- Place switch in close proximity to the equipment and within easy reach of the operator.

- Mark the switch as the disconnecting device for the equipment.

NOTE: A single switch or circuit-breaker can drive more than one instrument.

8) When the NEUTRAL line is present, connect it to terminal 4.

9) To avoid shock and possible instrument damage, connect power last.
