2.4 Notes for operator protection

Live components
During operation and shortly after the system has been switched off with the Emergency Off
button, high voltages are still present in the inverter and its components. These voltages may
remain if the connection to the motor is not removed or grounded. This danger exists with
permanent-magnet synchronous motors and synchronous motors which are not de-excited
immediately. These voltages may remain if the connection to the motor is not removed or
grounded. High voltages cause death or serious injury if the safety instructions are not
observed or if the equipment is handled improperly.
Never open the covers or doors when the system is in operation or while the DC link
capacitors are still discharging (in the case of current-source DC link inverters: commutation
capacitors). The DC link capacitors (commutation capacitors) can take up to 10 minutes to
discharge (or 5 minutes with compact devices) after the Emergency Off button is actuated.
Automatic startup
Depending on parameter settings and connection of external control devices, the inverter
can start up automatically when the line voltage is connected. This can result in death, serious
injury or material damage.
Confirm whether or not your system is capable of automatic starting and, if appropriate, take
measures to ensure personal safety and operational readiness at the driven machine.
2.4 Notes for operator protection
Read the following information about personal protection.
The unit meets the safety requirements as defined by IEC EN 61800‑5‑1 and UL 508 C.
Specialist personnel
Ensure that any transport, installation, operation or maintenance work is carried out by
qualified, trained staff. The minimum qualification must be that of an electrician in accordance
with EN 50110 "Operation of electrical systems".
For the purpose of these basic safety instructions, "skilled technical personnel" means people
who are familiar with the installation, mounting, commissioning and operation of the product.
They must be properly qualified for the tasks with which they are charged. Qualified personnel
must also be thoroughly familiar with all the safety-related instructions and measures described
in the product documentation.
