24 Safety instructions

General safety in operation

These instructions are for all personnel that operate the drive.
WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur.
• Keep the cabinet doors closed when the drive is powered. With the doors open,
a risk of a potentially fatal electric shock, arc flash or high-energy arc blast exists.
• If you have a cardiac pacemaker or other electronic medical device, keep away
from the area near motor, drive, and the drive power cabling when the drive is in
operation. There are electromagnetic fields present which can interfere with the
function of such devices. This can cause a health hazard.
• Give a stop command to the drive before you reset a fault. If you have an external
source for the start command and the start is on, the drive will start immediately
after the fault reset, unless you configure the drive for pulse start. See the firmware
manual.
• Before you activate the automatic fault reset or automatic restart functions of
the drive control program, make sure that no dangerous situations can occur.
These functions reset the drive automatically and continue operation after a fault
or supply break. If these functions are activated, the installation must be clearly
marked as defined in IEC/EN/UL 61800-5-1, subclause 6.5.3, for example, "THIS
MACHINE STARTS AUTOMATICALLY".
Note:
• The maximum number of drive power-ups is five in ten minutes. Too frequent
power-ups can damage the charging circuit of the DC capacitors. If you need to
start or stop the drive, use the control panel keys or commands through the I/O
terminals of the drive.
• If the drive is in remote control mode, you cannot stop or start the drive with the
control panel.
Additional instructions for permanent magnet motor
drives

Safety in installation, start-up, maintenance

￭
These are additional warnings concerning permanent magnet motor drives. The other
safety instructions in this chapter are also valid.
WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur.
If you are not a qualified electrical professional, do not do installation or
maintenance work.
• Do not do work on the drive when a rotating permanent magnet motor is
connected to it. A rotating permanent magnet motor energizes the drive including
its input and output power terminals.
