Safety in installation and maintenance
These instructions are for all who install or connect an option module to a unit 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.
1. If you are not a qualified electrician, do not do installation or maintenance work.
2. Isolate and disconnect the unit from all possible power sources. After you have
disconnected the unit, always wait for 5 minutes to let the intermediate circuit capacitors
discharge before you continue.
3. Disconnect all dangerous voltages connected to other connectors or parts in reach. For
example, it is possible that 230 V AC is connected from outside to a relay output of the
unit.
4. 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.
