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 a drive whose varistors are not disconnected is installed on an IT power
system (an ungrounded power system or a high resistance grounded [over 30
ohms] power system), the drive will be connected to earth potential through the
varistors. This may cause danger or damage the drive.
• If a drive whose varistors (built-in) or mains filter (external option) are not
disconnected is installed on an corner-grounded TN system, the drive will be
damaged.
• 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 or drive modules.
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.
