22 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.
