! SAFETY PRECAUTION � When the indicator is installed, connect an earth bonding conductor from FG to the earth connection marked “ ”. � Disconnect the mains power supply before opening the rear panel for whatever. � To install the optional interface cards, it is necessary to disconnect the mains power supply and fit a yellow/green earth bonding cable to the rear panel. (Fixed with another two earth bonding cables) � Before turning the power on ensure the supply voltage is within the acceptable range, AC 85 ~ 265 V. � The operating ambient temperature range is -10 ~ +40 °C (+14 ~ +104 °F). Thank you for purchasing EXCELL Check-weigh Indicator. To guide you to use our product correctly, please read the user manual carefully to avoid mis-operating this product.
