ed 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 CE conformity.
■POWER INPUT RATING & OPERATIONAL RANGE
•Locate the power input rating marked on the product and
confirm its operational range as indicated below:
24V DC rating: 24V ±10%, approx. 40mA
■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 the

•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.
