WARNING
♦ To ensure the safe operation of the equipment, it must be installed and
commissioned by qualified personnel in full compliance with the warnings laid
down in these operating instructions.
♦ Take particular note of the general and regional installation and safety
regulations regarding work on dangerous voltage installations (e.g. EN
50178), as well as the relevant regulations regarding the correct use of tools
and personal protective gear.
♦ The mains input, DC and motor terminals, can carry dangerous voltages even

switching off before carrying out any installation work.
♦ The inverters can be mounted adjacent to each other. If they are mounted on
top of each other, however, a clearance of 100 mm has to be observed.
