shall not be liablefor user’s failure to complywith these requirements.
The Genesys power supplyserieshas been evaluated to INSTALLATION CATEGORY II.
Installationcategory(over voltage category) II: locallevel,appliances, portable equipment etc.. With
smaller transient over voltage than Installation Category(over voltagecategory) III.
ThisproductisaSafetyClass 1instrument. To minimize shock hazard, the instrumentchassis must
be connectedtoanelectricalground. The instrument mustbe connectedto the AC power supply
mains through athree conductorpower cablefor SinglePhase modelsand throughafour conductor
power cablefor Three Phase modelswith theground wire firmly connectedtoanelectricalground
(safety ground) at the power outlet.
For instruments designed to be hard-wired to the supply mains,the protective earth terminal must
be connectedtothe safety electricalground before anotherconnectionis made. Any interruptionof
theprotective ground conductor, or disconnectionofthe protective earth terminal will cause a
potentialshock hazardthat might causepersonal injury.
Thereisapotentialshock hazardatthe RS232/485 and the IEEE ports when using power supplies
with ratedorcombinedvoltage greater than 400V and the Positive Output of the Power Supplyis
grounded. Do Not connect the Positive Output to ground when usingthe RS232/485orIEEE.
Fuses mustbechanged by authorized service personnelonly. For continued
protection against risk of fire,replace onlywith thesame type
and ratingoffuse. Refer to
maintenanceinstructions in chapter 9for fusesrating.
The Genesys power supply units havefuses in allsupplyconductots.To prevent potential risk of
hazard duringservicing, the unitshallbefully disconnected from thesupply.
Do not useACsupply which exceeds the input voltage and frequency rating of this instrument. The
input voltage and frequencyratingofthe Genesys power supply series is:190-240V~, 50/60Hz for
Three Phase 200V models and 380-415V~, 50/60Hz forThree Phase 400V models. For safety
reasons,the mains supplyvoltage fluctuations should not exceed +/-10% of nominal voltage.
Operating personnel must not removethe instrument cover.Nointernal adjustment or component
