6.9 Connecting to the mains network
An electrical wiring diagram is delivered with the hoist. Carry out the following procedures before
connecting the hoist to the mains network:
• Check that the rated voltages correspond to the main voltage. The voltages and frequencies marked
on the rating plate of motors driven by inverter can deviate from the values on the rating plate for the
hoist.
• If the hoist has been in storage for a long time or has been transported by sea, check that the motors
are dry and measure their insulation resistance.
• Ensure that the power supply to the hoist is protected with fuses of the correct size.
• Check that the phase sequence is correct.
• Carefully check all connections.
