6.2 Connection best practices

6.2.1 Wiring best practices

RISK OF ELECTRIC SHOCK AND FIRE
• Do not use the device with loads greater than those indicated in the technical specifications.
• Do not exceed the temperature and humidity ranges indicated in the technical specifications.
• Usetherequiredsafetyinterlocks(disconnectors)ofasuitablesizebetweenthepowersupplyandthehumidifier.
• Only use cables with a suitable cross-section as indicated in the section "Wiring best practices".
Whenwiringthehumidifiers,observethefollowinginstructions:
• Makesuretheoperatingenvironmentandconditionsfallwithinthespecifiedvalues.
• Usecablesofthecorrectdiameter,suitedtothevoltageandcurrentrequirements.
LOOSE WIRING CAN RESULT IN ELECTRIC SHOCK AND OVERHEATING
Tighten connections in compliance with the technical specifications for torque values.
MALFUNCTIONING OF THE EQUIPMENT
• Performthewiringcarefully,incompliancewithelectromagneticcompatibilityandsafetyrequirements.
• Carry out a full start-up test.
• Makesurethewiringiscorrectforthefinalapplication.
• Minimise the length of the connections as much as possible and avoid winding the cables around electrically connected parts.
• Beforeapplyingthepowersupply,checkallthewiringconnections.
• Do not connect cables to unused terminals and/or to terminals labelled "No connection "(N.C.)".
