Electrical / Mechanical Installation
Important
A time delay of approx. 3 - 30 sec will occur at start up. If the PCB is dismounted from the metal housing,
the warranty will be void. Before handling the frequency converter, it must have been disconnected from
supply power for at least 5 min.
Location
The frequency converter is cooled by passive air circulation. To avoid reduced operation or operating stops
due to overheating of the frequency converter, the frequency converter must be mounted vertically on a
metal plated wall with the glands facing downwards. The frequency converter must be mounted with space
around it to ensure sufficient cooling by allowing free circulation of air. Make sure that the mounting
surface can withstand the temperature of the surface of the frequency converter.
Operating temperature
The frequency converter must be installed in a well ventilated enviroment. The surrounding temperature
must not exceed 40°C and the frequency converter must never be mounted in a location where it is
exposed to direct sun light.
The E1045-1500 will be able to run at maximum supply power without additional cooling at 40°C ambient
temperature.
The E1045-2000 will be able to run up to 1650W supply power without additional cooling at 40°C ambient
temperature. When running at more than 1650W power supply the E1045-2000 will need additional
cooling. This should be done by making sure that there is a sufficient airflow through the cooling fins of the
heat sink.
The frequency converter will reduce performance of the motor, if a too high temperature is measured. By
default, this temperature is set at maximum, but it can be adjusted down through the ModBus
–
interface.
