40 Safety Requirement General Safety Summary Please review the following safety precautions carefully before putting the instrument into operation so as to avoid any personal injury or damage to the instrument and any product connected to it. To prevent potential hazards, please follow the instructions specified in this manual to use the instrument properly. Use Proper Power Cord. Only the exclusive power cord designed for the instrument and authorized for use within the local country could be used. Ground the Instrument. The instrument is grounded through the Protective Earth lead of the power cord. To avoid electric shock, connect the earth terminal of the power cord to the Protective Earth terminal before connecting any input or output terminals. Connect the Probe Correctly. If a probe is used, do not connect the ground lead to high voltage since it has isobaric electric potential as the ground. Observe All Terminal Ratings. To avoid fire or shock hazard, observe all ratings and markers on the instrument and check your manual for more information about ratings before connecting the instrument. Use Proper Overvoltage Protection. Ensure that no overvoltage (such as that caused by a bolt of lightning) can reach the product. Otherwise, the operator might be exposed to the danger of an electric shock. Do Not Operate Without Covers. Do not operate the instrument with covers or panels removed. Do Not Insert Anything Into the Air Outlet. Do not insert anything into the air outlet to avoid damage to the instrument. Use Proper Fuse. Please use the specified fuses. Avoid Circuit or Wire Exposure. Do not touch exposed junctions and components when the unit is powered on. Do Not Operate With Suspected Failures. If you suspect that any damage may occur to the instrument, have it inspected by authorized personnel before further operations. Any maintenance, adjustment or replacement especially to circuits or accessories must be performed by II DG1000Z Quick Guide

41 authorized personnel. Provide Adequate Ventilation. Inadequate ventilation may cause an increase of temperature in the instrument, which would cause damage to the instrument. So please keep the instrument well ventilated and inspect the air outlet and the fan regularly. Do Not Operate in Wet Conditions. To avoid short circuit inside the instrument or electric shock, never operate the instrument in a humid environment. Do Not Operate in an Explosive Atmosphere. To avoid personal injuries or damage to the instrument, never operate the instrument in an explosive atmosphere. Keep Instrument Surfaces Clean and Dry. To avoid dust or moisture from affecting the performance of the instrument, keep the surfaces of the instrument clean and dry. Prevent Electrostatic Impact. Operate the instrument in an electrostatic discharge protective environment to avoid damage induced by static discharges. Always ground both the internal and external conductors of cables to release static before making connections. Use the Battery Properly. Do not expose the battery (if available) to high temperature or fire. Keep it out of the reach of children. Improper change of a battery (lithium battery) may cause an explosion. Use the specified battery only. Handle with Caution. Please handle with care during transportation to avoid damage to keys, knobs, interfaces, and other parts on the panels. DG1000Z Quick Guide III
