Electrical installation

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.
If the front cover (Frame Sizes FX and GX) has been removed, the fan
impeller is exposed. There is danger of injury when the fan is running.
CAUTION
The control, power supply and motor leads must be laid separately. Do not feed
them through the same cable conduit/trunking.
