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
DISCHARGE TIME!
Adjustable frequency drives contain DC link capacitors that
can remain charged even when the adjustable frequency
drive is not powered. To avoid electrical hazards,
disconnect AC line power, any permanent magnet type
motors, and any remote DC link power supplies, including
battery backups, UPS and DC link connections to other
adjustable frequency drives. Wait for the capacitors to fully
discharge before performing any service or repair work.
The wait time required is listed in the Discharge Time table.
Failure to wait for the specified period of time after power
has been removed to do service or repair could result in
death or serious injury.

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
with a min. 10 mm² Cu or an additional PG 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, MN90G.
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], contact Danfoss
regarding PELV.

connections or other power connections while
the adjustable frequency drive is connected to
line 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/Reset] key is not a safety switch. It does
not disconnect the adjustable frequency drive
from line power.
