Pulling the front part of the unit forcibly may separate
the front housing from the body housing. Touching ex-
posed internal power/input terminals may cause an elec-
tric shock if the unit is powered.

When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
•
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 -10 to +55°C
(14 to 131°F) with relative humidity within 30 to 90% 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.
