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 installation 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 mm
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.
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 1-90 Motor
Thermal Protection to [4] ETR trip.
WARNING
Installation at high altitudes
For altitudes above 6,600 feet [2 km], contact Danfoss.
