POWER INPUT RATING
•Operationalvoltagerange&powerconsumption
15V DC rating: Rating ±5%, approx. 7.5mA (with no load)
■
ENVIRONMENT
•Indooruse
•Donotinstalltheunitwhereitissubjectedtocontinuous
vibration. Do not apply physical impact to the unit.
•Environmentaltemperaturemustbewithin-25to+85°C
(-13to185°F)withrelativehumiditywithin30to90%RH
in order to ensure adequate life span and operation.

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 en-
dure it without breakdown, however, it may shorten ap-
propriate life duration.
CHECKING
1) Terminal wiring: Check that wiring is correctly connect-
ed according to the connection diagram.
