The mains connection cable, the mains connection fuse links and any devices to disconnect and switch the po‐
werfeed must be available on site in order to connect the unit to the power supply. A 4-lead cable with a PE earth
conductor which complies with the table in  "Hoist motor data", Page 20 is required for the power supply.
Please note that the length of the supply cable specified for a given cross-section must not be exceeded in order
to avoid excessive voltage drop and malfunctions during start-up of the motor caused by undervoltage.
Connection to the electric supply
● First check to ensure that the voltage and frequency specified on the rating plate match your mains supply.
Ensure that the mains connection cable is not connected to the power supply and secured against accidental
restoration of the power supply.
● Remove the service cover to connect the supply cable.
● Use the mains connection set included in the delivery for the plug connection to the mains connection cable.
