BEFORE USE ....Thank you for choosing M-System. 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 M-System’s Sales Office or representatives.

■ PACKAGE INCLUDES: Temperature control module (control module + CJC sensor, 2 pcs.) .......................... (1)

■ MODEL NO.Confirm that the model number described on the product is exactly what you ordered.

■ INSTRUCTION MANUALThis manual describes necessary points of caution when you use this product, including installation, connection and basic maintenance procedures.

POINTS OF CAUTION■ HOT INSERTION/REMOVAL OF MODULESRemoving or replacing modules does not affect other mod-ules on the same backplane. It is possible to replace them without removing the power supply. However, replacing multiple modules at once may greatly change line voltage levels. We recommend that you replace them one by one.

■ ENVIRONMENT•Indooruse•Whenheavydustormetalparticlesarepresentintheair,

install the unit inside proper housing with sufficient ven-tilation.

•Donotinstalltheunitwhereitissubjectedtocontinuousvibration.Donotsubjecttheunittophysicalimpact.

•Environmentaltemperaturemustbewithin-10to+55°C(14to131°F)withrelativehumiditywithin30to90%RHin order to ensure adequate life span and operation.

■ WIRING•Do not install cables (power supply, input and output)

close to noise sources (relay drive cable, high frequency line, etc.).

•Do not bind these cables together with those in whichnoisesarepresent.Donotinstalltheminthesameduct.

■ UNUSED INPUT CHANNELS•Unused channels canbe specifiedand set so on thePC
