Electrical Installation
The voltage on the frequency converter is
dangerous when the unit is connected to
mains. Incorrect installation of the motor
or frequency converter may lead to material damage
or serious injury or it may be fatal. Consequently, the
instructions in this manual as well as national and
local rules and safety regulations must be complied
with. Touching the electrical parts may be fatal, even
after the mains supply has been disconnected. Wait
at least 15 minutes if using VLT 5052-5102.
NB!:
It is the user
’
s or certified electrician
’
s
responsibility to ensure correct earthing and
protection in accordance with applicable
national and local norms and standards.
All terminals for the control cables are located under
the protective cover of the frequency converter. The
protective cover (see drawing) can be removed by
means of a pointed object - a screwdriver or similar.
Once the protective cover has been removed, the
actual EMC-correct installation can start.
