KEEP AWAY FROM LIVE CIRCUITS.
Operating personnel must not remove instrument covers. Component replacement and
internal adjustments must be made by qualified service personnel. Do not replace
components with power cable connected. Under certain conditions, dangerous voltages
may exist even with the power cable removed. To avoid injuries, always disconnect power,
discharge circuits and remove external voltage sources before touching components.
DO NOT SERVICE OR ADJUST ALONE.
Do not attempt internal service or adjustment unless another person, capable of rendering
first aid and resuscitation, is present.
DO NOT EXCEED INPUT RATINGS.
This instrument may be equipped with a line filter to reduce electromagnetic interference
and must be connected to a properly grounded receptacle to minimize electric shock
hazard. Operation at line voltages or frequencies in excess of those stated on the data plate
may cause leakage currents in excess of 5.0 mA peak.
DO NOT EXCEED LOAD INPUT VOLTAGE RATING.
WARNING
DO NOT EXCEED LOAD INPUT VOLTAGE RATING
This instrument does NOT have a means to disconnect its Load input from a
connected power supply. If the voltage applied to the Load input exceeds its
maximum rating – even if the load is turned completely off – damage to the load
WILL occur. Damage caused by exceeded maximum load input voltage under any
circumstance is NOT covered by the manufacturer’s product warranty. Remove any
load input connections when the load is not in use, even when it is turned off.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT.
Because of the danger of introducing additional hazards, do not install substitute parts or
perform any unauthorized modification to the instrument. Return the instrument to an
Adaptive Power Systems Sales and Service Office for service and repair to ensure that safety
features are maintained.
Instruments that appear damaged or defective should be made inoperative and secured
against unintended operation until they can be repaired by qualified service personnel.
