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. 15VA at 100V AC
approx. 20VA at 200V AC
approx. 21.5VA at 240V AC
24V DC rating: 24V ±10%, approx. 8.5W
■
HOT-SWAPPABLE MODULES
• The module can be replaced while the power is ON. Be
sure to replace it when the module is not communicat-
ing with a host, as it may affect the system. Replacing
multiple modules at once may greatly change line voltage
levels. We highly recommend to replace them one by one.
■
ENVIRONMENT
• Indoor use.
• Attach the antenna to the unit.
• 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.
• Attachment and adjustment of sleeve antenna: Loosen
the connector (See the below figure), and rotate the an-
tenna. Holding the antenna vertically, tighten the connec-
tor by hand. Make sure to fix the antenna firmly.
Connector
• Attachment of rooftop antenna: The magnet on the bottom
face allows the antenna to be attached on a metal box and
such. To obtain optimum performance from the antenna,
attach it on a metal plate (recommended dimension: 500
mm × 500 mm or more). However, in the case of connect-
ing FE1 or FG of the power supply module to a metal
plate, the isolation between FE1 or FG and the internal
bus or internal power or antenna connector will be lost.
Tighten the connector with a specified torque (0.9 N∙m).
As a guide, finger-tighten the connector until it stops, and
then rotate it 10 to 15 degrees with a wrench. Do not force
the cable to bend beyond the acceptable bending radius
of 3 cm.
• Please note that using 7.5 m coaxial cable (model: CX-
SAC0SAD0Q0750) (OKI) for extension decreases trans-
mission distance.
■
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.
