POINTS OF CAUTION

Thank you for choosing us. Before use, please check contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact our sales office or representatives.

■ CONFORMITY WITH EU DIRECTIVE• Use dual-shield cables (Shinko Seisen Industry Model
ZHY262 PBA) for the network. If it is not sufficient, usea ferrite core (Kitagawa Industries Model GRFC-13) for
the network cable.
• The equipment must be mounted inside the instrument
panel of a metal enclosure.
• The actual installation environments such as panel configurations, connected devices, connected wires, may affect the protection level of this unit when it is integrated
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 the CE conformity.

■ PACKAGE INCLUDES:
DC voltage input module.....................................................(1)■ MODEL NO.
Confirm Model No. marking on the product to be exactly
what you ordered.
■ INSTRUCTION MANUALThis manual describes necessary points of caution when
you use this product, including installation, connection andbasic maintenance procedures.

■ POWER INPUT RATING & OPERATIONAL RANGE• Locate the power input rating marked on the product andconfirm its operational range as indicated below:		 24V DC rating: 24V ±10%, approx. 50mA
■ GENERAL PRECAUTIONS• Before you remove the unit or mount it, turn off the power
supply and input signal for safety.
• DO NOT set the switches on the module while the poweris supplied. The switches are used only for maintenancewithout the power.
■ ENVIRONMENT• Indoor use.
• When heavy dust or metal particles are present in theair, install the unit inside proper housing with sufficientventilation.
• 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.
■ WIRING• Do not install cables close to noise sources (relay drivecable, 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 supplied, however, a warm up for 10 minutes is required forsatisfying complete performance described in the data
sheet.
