Options
Error-switch-off is effected at:
− Maximum heat sink temperature
− Maximum interior temperature
In the factory setting a warning message is triggered when
− the maximum heat sink temperature is reached (minus 5 °C)
− the maximum interior temperature is reached (minus 5 °C)
The warning messages can be output via digital outputs.

WARNING
To avoid serious physical injury or considerable damage to property, only qualified staff
may work on the devices.
During operation, the heat sink can reach a temperature of up to 75 °C.
the heat sink during operation.
The heat sink may be hot even some time after the frequency inverter was switched off.
Comply with the following requirements:
− The installation surface of the external heat sink must at least be as large as the cold plate surface.
− The contact surfaces of the external heat sink and cold plate must be plane.
− The contact surfaces must be clean and degreased.
• For fixing the frequency inverter, drill 6 threaded holes M6 in the installation surface. For the in-
stallation dimensions, refer to the following chapters.
• Deburr the threaded holes.
• Clean the contact surfaces of the external heat sink and cold plate.
• Apply a thin and uniform film of heat conducting paste on the cold plate.
The heat conducting paste compensates the roughness of the contact surfaces and
thus the heat transmission resistance between the cold plate and the heat sink. In this
way, the cooling efficiency is increased.
• Mount the frequency inverter vertically on the heat sink using six M6 bolts. The bolts must have a
minimum length of 30 mm. Tighten all bolts uniformly.
The maximum tightening torque of the fixing bolts in a typical construction is 3.4 Nm.
After the mechanical installation continue with the electrical installation according to chapter 5
“Electrical Installation”. Comply with the safety instructions provided there.
