1.1.1 High Voltage Warning

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.

1.1.2 Safety Instructions

CAUTION
Before using functions directly or indirectly influencing
personal safety (e.g. Safe Stop, Fire Mode or other
functions either forcing the motor to stop or attempting to
keep it functioning) a thorough risk analysis and system
test must be carried through. The system tests must
include testing failure modes regarding the control
signaling (analog and digital signals and serial communi-
cation.
NOTE
Before using Fire Mode, contact Danfoss
•
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
disconnect the frequency converter from mains.

1.1.4 General Warning

WARNING
ELECTRICAL SHOCK 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 4 min for all sizes.
Shorter time is allowed only if indicated on the nameplate
for the specific unit.
