1. INTRODUCTION
This manual contains installation, operation and maintenance instructions for the US-4011 indicators. Please read this
manual completely before installation and operation.
1.1. Safety Precautions
For safe and dependable operation of this equipment, please comply with the following safety precautions:
l Verify that the input voltage range printed on the data label matches the local AC power to be used.
l Make sure that the power cord does not pose a potential obstacle or tripping hazard.
l Use only approved accessories and peripherals.
l Operate the equipment only under ambient conditions specified in these instructions.
l Disconnect the equipment from the power supply when cleaning.
l Do not operate the equipment in hazardous or unstable environments.
l Do not immerse the equipment in water or other liquids.
l Service should only be performed by authorized personnel.
NOTE: Some functions maybe disabled by manufacture before shipping, if you need these functions or don’t want to
use some other functions, please contact with manufacture in advance, because of this, some operations or faceplate
maybe are a little bit different, and some description sections may be deleted.
