WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or death,
or damage to the equipment can occur. If you are not a qualified electrical
professional, do not do installation or maintenance work.
WARNING!
Beware of hot coolant. Do not work on the liquid cooling system until the pressure
is lowered down by stopping the pumps and draining the coolant. High-pressure
warm coolant (6 bar, max. 50 °C) is present in the internal cooling circuit when it
is in operation.

Use the required personal protective equipment. Wear protective gloves and long
sleeves. Some parts have sharp edges.
