WARNING
Theoperationslistedbelowmustbeperformed
byskilledpersonnel.
1)Beforeconnectingtheelectricsystem,makesurethat:
·
thepowersupplyplanttotheliftisequippedwiththeprotection
devicesrequiredbycurrentstandardsinthecountrywherethe
machineryisinstalled.
·
thepowersupplylinehasthefollowingcross-section:
Liftvoltage400V,three-phase: .................minimum2.5mm2
Liftvoltage230V,three-phase: ................. minimum4mm2
Liftvoltage230V,single-phase: ................minimum6mm2
·
thevoltageoscillationsarewithinthetolerancerangesetforth
bythespecifications.
Provideprotectionfrom10Aforthree-phaseoperationand
16Aforsinge-phaseoperation.
