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.

(14 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.

■ WIRING

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 ....
