POINTS OF CAUTION
■POWER INPUT RATING & OPERATIONAL RANGE
•Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 240V AC rating: 85 – 264V, 47 – 66 Hz, approx. 10VA
24V DC rating: 24V ±10%, approx. 7W
■GENERAL PRECAUTIONS
•Before you remove the module, turn off the power supply,
input signal and output signal for safety.
■ENVIRONMENT
•Indoor use.
•When heavy dust or metal particles are present in the air,
install the module inside proper housing with sufficient
ventilation.
•Do not install the module where it is subjected to continu-
ous vibration. Do not subject the unit to physical impact.
•Environmental temperature must be within -5 to +60°C
(23 to 140°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
•Wrong connection may damage the module.
•Do not connect cables to moving parts or pull them tightly.
•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 module is designed to function as soon as power is
supplied, however, a warm up for 10 minutes is required
for satisfying complete performance described in the data
sheet.
