1.2 Safety Instructions
1.2.1 High Voltage Warning
WARNING
The voltage of the variable speed drive is dangerous
whenever it is connected to mains. Incorrect installation of
the variable speed drive may cause damage to the
equipment, serious injury or death. Consequently, it is
essential to comply with the instructions in this manual as
well as local and national rules and safety regulations.
1.2.2 Safety Instructions
•
Make sure the drive is properly connected to
earth
•
Do not remove the mains connector or motor
(compressor) connector while the drive is
connected to power
•
Protect personnel against supply voltage
•
Protect the variable speed drive against over-
current according to national and local
regulations
•
The earth leakage current exceeds 3.5 mA
•
A stop command does not disconnect power
from the drive
