COSMOS DRIVER SERIES 3000 - USE AND MAINTENANCE MANUAL
3.3 Precautions against risk of Electric Shock
The high voltage of some accessories and components in the driver might cause electrocution, if the
user came into contact with them. The connectors with a dangerous voltage are: MOTOR/J4,
BRAKE R/J2, DC BUS/J3, LINE/J1.
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 installation,
because they might cause short-circuits.
The driver is an electric generator. The running speed becomes electric potential. High voltage 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 specific 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.
