2.1.1 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 causedeath, serious
injury or damage to the equipment. Consequently, it is
essential to comply with the instructions in this manual as
well as local and national rules and safety regulations.

2.1.2 Safety Instructions

CAUTION
Prior to using functions directly or indirectly influencing
personal safety (e.g. 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 signalling (analog and
digital signals and serial communication.
•
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.

2.1.3 General Warning

WARNING
Warning:
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), as well
as the motor connection for kinetic back-up.
Before touching any potentially live parts of the frequency
converter, wait at least as follows: Be aware that there may
be high voltage on the DC link even when the Control
Card LEDs are turned off. A red LED is mounted on a
circuit board inside the drive to indicate the DC bus
voltage. The red LED will stay lit until the DC link is 50 Vdc
or lower.
Voltage
380 - 480V
525 - 600V
Be aware that there may be high voltage on the DC link even
when the LEDs are turned off.
WARNING
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 by means of:
a min. 10mm2 Cu or 16mm2 Al PE-wire or an addtional PE
wire - with the same cable cross section as the Mains
wiring - must be terminated separately.
Residual Current Device
This product can cause a D.C. 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 earthing of the frequency converter and the use
of RCD's must always follow national and local regulations.
