16 Safety instructions
Additional instructions and notes
WARNING!
Obey these instructions. If you ignore them, injury or death, or
damage to the equipment can occur.
• If you install the drive on an IT system (an ungrounded power system or a high-
resistance-grounded [over 30 ohms] power system), disconnect the internal EMC
filter; otherwise the system will be connected to ground potential through the EMC
filter capacitors. This can cause danger or damage the drive.
Note:
Disconnecting the internal EMC filter increases the conducted emission
and reduces the drive EMC compatibility considerably.
• If you connect the drive to an IT system (an ungrounded power system or a high-
resistance-grounded [over 30 ohms] power system), disconnect the varistor from
ground. Failure to do so can cause damage to the varistor circuit.
• If you install the drive on a corner-grounded TN system, disconnect the internal
EMC filter; otherwise the system will be connected to ground potential through the
EMC filter capacitors. This will damage the drive.
Note:
Disconnecting the internal EMC filter increases the conducted emission
and reduces the drive EMC compatibility considerably.
• Use all ELV (extra low voltage) circuits connected to the drive only within a zone
of equipotential bonding, that is, within a zone where all simultaneously
accessible conductive parts are electrically connected to prevent hazardous
voltages appearing between them. You can accomplish this by a proper factory
grounding, that is, make sure that all simultaneously accessible conductive parts
are grounded to the protective earth (PE) bus of the building.
• Do not do insulation or voltage withstand tests on the drive.
Note:
• The motor cable terminals of the drive are at a dangerous voltage when the input
power is on, regardless of whether the motor is running or not.
• The DC and brake resistor terminals (UDC+, UDC-, R+ and R-) are at a
dangerous voltage.
• External wiring can supply dangerous voltages to the terminals of relay outputs.
• The Safe torque off function does not remove the voltage from the main and
auxiliary circuits. The function is not effective against deliberate sabotage or
misuse.
WARNING!
Use a grounding wrist band when you handle the printed circuit
boards. Do not touch the boards unnecessarily. The components on the boards
are sensitive to electrostatic discharge.
