3.3 Precautions against risk of Electric Shock
The high voltage of some accessories and components in the servo-driver/inverter might
cause electrocution, if the user came into contact with them. Be careful to the terminal
boards and to the motor/dynamic brake connection.
There are some condensers inside the driver which maintain a dangerous voltage for at
least 6 minutes after switching them off. Before starting any operation, make sure that the
driver has been switched off at least 6 minutes earlier and that the motor is still.
Avoid any metal components (screws, electrical cables…) fall into the driver during the in-
stallation, because they might cause short-circuits.
The driver is an electric generator. The running speed becomes electric potential. High volt-
age is already generated at 300 rpm.
During installation and maintenance, disconnect the device from the mains power supply.
Risk of Electric Shock.
Some components (such as the aluminium heat sink) are made of conductive materials.
They must be safely connected to the protective conductor (PE/Ground) by using the spe-
cific terminal strips, in order to avoid Electric Shock.
Never use the device if it is partially or totally disassembled. Risk of Electric Shock and/or
damages to people and properties.
