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

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 with a min.
10 mm 2 Cu or an additional 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,
MN90G.
Protective earthing of the frequency converter and the
use of RCDs must always follow national and local
regulations.
Motor thermal protection
Motor overload protection is possible by setting 1-90 Motor
Thermal Protection to [4] ETR trip.
WARNING
Installation at high altitudes
For altitudes above 2 km, contact
Danfossregarding PELV.
