1.1.1 Warnings

WARNING
High Voltage Warning
The voltage of the Adjustable frequency drive is dangerous
whenever it is connected to line power. Incorrect instal-
lation of the motor or Adjustable frequency 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.
WARNING
Electrical Hazard
Touching the electrical parts may be fatal - even after the
equipment has been disconnected from line power. Also
make sure that other voltage inputs have been discon-
nected (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 Adjustable frequency drive, wait at least as
stated in the table below:
Voltage (V) Power range (HP/kW)
3 x 200 0.34–5 [0.25–3.7]
3 x 200 7.5–15 [5.5–11]
3 x 400 0.5–10 [0.37–7.5]
3 x 400 15–125 [11–90]
3 x 600 3–10 [2.2–7.5]
3 x 600 15–125 [11–90]

CAUTION
Leakage Current:
The ground leakage current from the Adjustable frequency
drive exceeds 3.5 mA. According to IEC 61800-5-1, a
reinforced protective ground connection must be ensured
by means of a min. 0.016 in² [10 mm²] Cu or an additional
PE wire - with the same cable cross-section as the line
power 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, MN90GXYY.
Protective grounding of the Adjustable frequency drive
and the use of RCDs must always follow national and local
regulations.
Motor thermal protection:
Motor overload protection is possible by setting Parameter
1-90 Motor thermal protection to the value Electronic
Thermal Relay (ETR) trip.
Installation at high altitudes
For altitudes above 6,600 feet [2 km], please contact
Danfoss regarding PELV.

WARNING
•
Make sure the Adjustable frequency drive is
properly grounded.
•
Do not remove AC line input connections, motor
connections or other power connections while
the Adjustable frequency drive is connected to
power.
•
Protect users against supply voltage.
•
Protect the motor against overloading according
to national and local regulations.
•
The ground leakage current exceeds 3.5 mA.
•
The [OFF] key is not a safety switch. It does not
disconnect the Adjustable frequency drive from
line power.
