DANGER
Ignoring this indication or wrong handling may lead to an
imminent danger such as death or serious injury.
WARNING
Ignoring this indication or wrong handling may result in death or
serious injury.
CAUTION
Ignoring this indication or wrong handling may cause injury to
people or property damage only.
⚫Installation
Although there is no restriction in particular on the installing position, the installation place should
be free from dust and moisture so as to prevent insulation failure due to dewing. Due attention
should be paid to the installation environment such as improving ventilation by installing a cooling
fan if temperature rise is expected due to apparatuses around the product. Avoid the installation
at a place subject to continuous vibration because there is the possibility of contact failure
of cable connections.
CAUTION
Never install the product at a humid or moist place. It is dangerous
because electric shock will be caused.
Do not install it at a place where ambient temperature is very high.
Internal circuits may be damaged due to high temperature.
Installation at a place subject to constant vibration may result in contact
failure of cable connections.

Failure
If any failure of this unit is suspected, it must be checked at a safe place such as check terminals of
the connected apparatuses instead of checking the output voltage, etc. with the connector pins of
this apparatus, to prevent short-circuit, etc.
In case of failure, contact our company.
DANGER
Never disassemble the product. Touching the interior is very dangerous
because there is the possibility of electrical shock.

Jumper of indicated value to be set of jumper pins (A,
B, C, D) (for the indicated value, see the left table).
After setting (A, B, C, D), the decimal point is set with
(JP1, JP2, JP3) (see Fig. 1) to complete the full-scale
change.
* When the setting is changed, the full-scale value
may be deviated, and in such a case, the full-scale
adjustment should be made.
Full-scale adjustment
If the full scale is deviated, adjust it by turning the adjusting volume on the left side of Fig. 2.
