POINTS OF CAUTION■ CONFORMITY WITH EU DIRECTIVES LEGISLATION• The equipment must be mounted inside a panel.
• The actual installation environments such as panel configurations, connected devices, connected wires, may affectthe protection level of this unit when it is integrated in apanel system. The user may have to review the CE requirements in regard to the whole system and employ additional protective measures* to ensure the CE conformity.
* For example, installation of noise filters and clamp filters for the power source, input and output connectedto the unit, etc.

INSTALLATION
Set the unit so that its DIN rail adapter is at the bottom.
■ MOUNTING THE UNIT ON A DIN RAIL
A) Hang the upper hook at the rear side of unit on the DINrail.
B) Push in the lower in keeping pressing the unit to the DINrail.

■ POWER INPUT RATING & OPERATIONAL RANGE• Locate the power input rating marked on the product andconfirm its operational range as indicated below:		 85 – 264V AC rating: 85 – 264V, 47 – 66 Hz, approx. 2 – 3VA		 24V DC rating: 24V ±10%, approx. 2W

DIN RailAB■ GENERAL PRECAUTIONS• Before you remove the unit or mount it, turn off the power
supply and input signal for safety.
■ ENVIRONMENT• Indoor use.
• When heavy dust or metal particles are present in theair, install the unit inside proper housing with sufficientventilation.
• Do not install the unit where it is subjected to continuousvibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -5 to +55°C(23 to 131°F) with relative humidity within 0 to 90% RH
in order to ensure adequate life span and operation.
■ WIRING• Do not install cables close to noise sources (relay drivecable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
• Install lightning surge protectors for those wires connect-■ REMOVING THE UNIT
A) Push down the DIN rail adaptor using a minus screwdriver.
B) Pull out the lower part of the unit.
C) Remove the upper part from the DIN rail.

TERMINAL CONNECTIONSADJUSTMENT PROCEDURE

Connect the unit as in the diagram below or refer to the connection diagram on the front of the unit.

This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any calibration.
For matching the signal to a receiving instrument or in caseof regular calibration, adjust the output as explained in thefollowing.

Use a signal source and measuring instruments of sufficientaccuracy level. Turn the power supply on and warm up for
more than 10 minutes.
1) ZERO: Apply 0% input and adjust output to 0%.

2) SPAN: Apply 100% input and adjust output to 100%.
3) Check ZERO adjustment again with 0% input.
4) When ZERO value is changed, repeat the above procedure 1) – 3).

OUTPUT■ CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accuracy described in the data sheet. When the output is out oftolerance, recalibrate the unit according to the “ADJUSTMENT PROCEDURE” explained earlier.

WIRING INSTRUCTIONS■ SCREW TERMINALTorque: 0.8 N·m

CHECKING
1) Terminal wiring: Check that all cables are correctly connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
7 – 8 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% ofthe full-scale.
4) Output: Check that the load resistance meets the described specifications.
