WARNING

The inverter must always be grounded.

♦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.

♦Never use high voltage insulation test equipment on cables connected to the inverter.

♦The mains input, DC and motor terminals, can carry dangerous voltages even if the inverter is inoperative; wait 5 minutes to allow the unit to discharge after switching off before carrying out any installation work.

CAUTION

The control, power supply and motor leads must be laid separately. Do not feed them through the same cable conduit/trunking.
