1.1 Safety

1.1.1 Warnings

WARNING
High Voltage Warning
The voltage of the frequency converter is dangerous
whenever it is connected to mains. Incorrect installation of
the motor or frequency converter 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.
WARNING
Electrical Hazard
Touching the electrical parts may be fatal - even after the
equipment has been disconnected from mains. Also make
sure that other voltage inputs have been disconnected
(linkage of DC intermediate circuit). Be aware that there may
be high voltage on the DC link even when the LEDs are
turned off. Before touching any potentially live parts of the
frequency converter, wait at least as stated in the table
below:
Voltage (V)
3 x 200
3 x 200
3 x 400
3 x 400
CAUTION
Leakage Current:
The earth leakage current from the frequency converter
exceeds 3.5 mA. According to IEC 61800-5-1 a reinforced
Protective Earth connection must be ensured by means of a
min. 10mm² Cu or an addtional PE wire - with the same cable
cross section as the Mains wiring - must be terminated
separately.
Residual Current Device:
This product can cause a DC current in the protective
conductor. Where a residual current device (RCD) is used for
extra protection, only an RCD of Type B (time delayed) shall
be used on the supply side of this product. See also Danfoss
Application Note on RCD, MN.90.GX.YY.
Protective earthing of the frequency converter and the use
of RCDs must always follow national and local regulations.

1.1.2 Safety Instructions

•
Make sure the frequency converter is properly
connected to earth.
•
Do not remove mains connections, motor
connections or other power connections while the
frequency converter is connected to power.
•
Protect users against supply voltage.
•
Protect the motor against overloading according to
national and local regulations.
•
The earth leakage current exceeds 3.5 mA.
•
The [OFF] key is not a safety switch. It does not
