Warning: Do not operate the supplied humidifier in combustible or explosive surroundings.
Warning: Do not operate the supplied humidifier if there is any damage to the cabinet or any
components in humidifier are damaged.
Warning: The main switch should be a connection breaker which has over current and leakage
current protecting functions per code EN60947-3 or EN60947-2 if point gap required by EN60947-3
can be fulfilled.
4. Physical environment and operating conditions
 •Ambienttemperature+4°C~+38°C(40°Fto100°F)
 •Humidity=50%at40°C(104°F),=90%at20°C(68°F)
 •Altitude=1000m(abovemeansealevel)(3300ft)
5. Transportation and storage conditions
Electrical equipment shall be designed to withstand, or suitable precautions shall be taken to
protect against, the effects of transportation and storage temperatures within a range of
 -25°Cto+55°C(-15°Fto130°F)andforshortperiodsnotexceeding24h,upto+70°C(160°F). 
Suitable means shall be provided to prevent damage from humidity, vibration and shock.
6. Requirements
 Thesupplydisconnectingdevice(i.e.aswitch-disconnect,adisconnectusedincombinationwith 
 switchingdevices,oracircuit-breaker)shallfulfillallofthefollowingrequirements:
 • IsolatetheelectricalequipmentfromthesupplyandhaveoneOFF(isolated)andoneON 
  positiononly,clearlymarkedwith“O”and“I”(symbols60417-2-IEC-5008and
  60417-2-IEC-5007,see10.2.2),withtheactuatingdirectionsinaccordancewithIEC60447. 
  Circuit-breakerthat,inaddition,hasareset(tripped)positionbetween“O”and“I”arealso 
deemed to satisfy this requirement.
 • HaveavisiblegaporapositionindicatorwhichcannotindicateOFF(isolated)untilallcontacts 
are actually open and there is an adequate isolating distance between all the contacts in
accordance with IEC 60947-3.
 • BeprovidedwithameanspermittingittobelockedintheOFF(isolated)position
  (e.g.bypadlocks).Whenlocked,remoteaswellaslocalclosingshallbeprevented.
 • Disconnectallliveconductorsofitspowersupplycircuit.However,forTNsupplysystems,the 
neutral conductor may or may not be disconnected. It is noted that in some countries,
  disconnectionoftheneutralconductor(whenused)iscompulsory.
 • Thehandleofthesupply-disconnectingswitchshallbelocatedbetween0.6mand1.7m
  (2ft.and5-1/2ft)abovetheservicinglevel.
 • Thedisconnectingswitchmusthaveovercurrentandoverloadprotectingfunctionsand  
initialize them as low as possible under normal running.
 • Thisdisconnectingswitchshouldhaveleakagecurrentprotectingfunction.Themaxleakage 
current should be less than 30mA.
