8 Safety instructions
General warning tells you about conditions, other than
those caused by electricity, which can cause injury or
death, or damage to the equipment.
Electrical safety precautions
These instructions are for all who install or connect an option
module to a drive and need to open its front cover or door to do the
work.
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.
1. Clearly identify the work location and equipment.
2. Disconnect all possible voltage sources. Make sure that re-
connection is not possible. Lock out and tag out.
•
Open the main disconnecting device of the drive.
•
If you have a permanent magnet motor connected to the
drive, disconnect the motor from the drive with a safety
switch or by other means.
•
Disconnect all dangerous external voltages from the
control circuits.
•
After you disconnect power from the drive, always wait 5
minutes to let the intermediate circuit capacitors discharge
before you continue.
3. Protect any other energized parts in the work location against
contact.
4. Take special precautions when close to bare conductors.
