are maintained. Prior to installation, check that the insu-
lation class of this unit satisfies the system requirements.
• Altitude up to 2000 meters.
• The equipment must be mounted inside a panel.
• The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con-
form to CE requirements. Failure to observe these re-
quirements may invalidate the CE conformance.
• The actual installation environments such as panel con-
figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated
in a panel 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 con-
formity.
* For example, installation of noise filters and clamp fil-
ters for the power source, input and output connected to
the unit, etc.
• Install lightning surge protectors for those wires connect-
ed to remote locations.

• Do not install the unit where it is subjected to continuous
vibration. 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 10 to 85% RH
in order to ensure adequate life span and operation.
• Be sure that the ventilation slits are not covered with ca-
bles, etc.
■WIRING
• Do not install cables close to noise sources (relay drive
cable, 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.
■AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.
• With voltage output, do not leave the output terminals
shortcircuited for a long time. The unit is designed to
endure it without breakdown, however, it may shorten ap-
propriate life duration.

and Y, which corresponds output of matched table, is the
output.
The range is available between -5 to +105 (%) for both X and
Y. For X, it is required to set in ascending order from X001.
Be sure that if it is set with other than ascending order, cor-
rect conversion is not carried out.

MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Without linearization, 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 sig-
nal remains within accuracy described in the data sheet. If
the output signal is out of accuracy, when the input display
value is out of accuracy, perform the input fine adjustment.
When the input display value is correct but the output is
out of accuracy, perform the output fine adjustment. Refer
to this manual, when adjusting with front buttons. Refer
to the M2ECFG users manual (EM-5147), when adjusting
with M2E Configurator Software (model: M2ECFG). And
then follow the procedure shown below.
• INPUT FINE ADJUSTMENT
1) Set the input signal to 0%, and adjust the input display to
0% by [69] Input Zero fine adjust.
2) Set the input signal to 100%, and adjust the input display
to 100% by [70] Input Span fine adjust.
3) Again set the simulated input to 0%, confirm the input
display.
4) If input display is shifted, repeat the procedure from 1) to
3).
• OUTPUT FINE ADJUSTMENT
1) Set the simulated input to 0%, and adjust the output sig-
nal to 0% by [71] Output Zero fine adjust.
2) Set the simulated input to 100%, and adjust the output
signal to 100% by [72] Output Span fine adjust.
3) Again set the simulated input to 0%, confirm the output
signal.
4) If output signal is shifted, repeat the procedure from 1) to
3).
