Danger! If the following instructions are not complied with, there is direct danger
with the possible consequences of death or severe injury by electrical
current. Further, failure to comply can lead to destruction of the fre-
quency inverter and/or of the expansion module.
• Before assembly or disassembly of the EM-SYS expansion module, the frequency
inverter must be de-energized. Take appropriate measures to make sure it is not
energized unintentionally.
• Make sure that the frequency inverter is de-energized.
Danger! The mains, direct voltage and motor sockets can have dangerous voltages
even after disconnection of the frequency inverter. Work may only be
done on the device after a waitin
g period of some minutes until the DC
link capacitors have been discharged.
