Even when the unit has been shut down, voltage will still be present at terminals
and connections of the EC fans. This means there is a risk of electric shock
that could result in injury or death.
Do not touch the EC fans for five minutes after disconnecting the power across
all poles.
Use a rubber mat if working on the unit when it is electrically charged.
Only use cables that meet local wiring regulations with regard to voltage, current,
insulation material, load etc. Always fit an earth conductor.
