12 Safety
Safety in installation
These warnings are intended for all who install or connect an optional module to a drive,
converter or inverter, and need to open its front cover or door to perform 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 electrician, do not do installation or maintenance work.
•
Disconnect the drive, converter or inverter from all possible power sources. After you
have disconnected the drive, converter or inverter, always wait for 5 minutes to let the
intermediate circuit capacitors discharge before you continue.
•
Disconnect all dangerous voltages connected to any control signal connectors in
reach. For example, it is possible that 230 V AC is connected from outside to a relay
output of the drive, converter or inverter.
•
Always use a multimeter to make sure that there are no parts under voltage in reach.
The impedance of the multimeter must be at least 1 Mohm.
